Knowledge is Power. Now our job is to prove this to the world. We so often want a crystal ball to gaze into our future. We have a number of crystal balls. These are crystal balls based on science and research, customized to our own unique DNA. I am referring to genetic testing, specifically BRCA testing.
Oncology massage is simply a massage in the context of someone going through cancer treatment. The most common cancer treatments are surgery, radiation and chemotherapy. Because these treatments often leave “injured areas” such as surgical incisions, radiation burns and general system fatigue, we have to know how to work with these conditions, to be able to give a good massage without hurting them. Studies have also shown that individuals that receive massage require less anti-nausea and pain reducing medication.
Occupational Therapists are trained to help people with illness or disability learn how to maintain their daily lifestyle. These daily routines help us feel in control of our lives, and illness forces us to change and become more dependent on others. There are ways to modify and adapt so that we can regain a greater sense of mastery over our lives even while undergoing treatment. Remember to first check with your physician to make sure that you receive medical clearance to engage in the following activities.
Here are some suggestions:
1. Take care of yourself by balancing work, rest, play and treatment. You may need to shift priorities and delegate responsibilities to others if able. It’s OK if the house is a little dirty.
2.Fatigue is the greatest side effects suffered after cancer treatment. However, research has found that exercise during treatment can actually counter the fatigue. Exercise improves quality of life, enhances function, and gives one a sense of control. Even starting with 5 minutes of exercise a day can be beneficial. The less you do, the more fatigue you will feel.
3. If you have received a TRAM FLAP reconstruction, putting on shoes and socks may be difficult. Assistive devices such as long shoe horns or stocking aides may make the process easier.
4. Peripheral neuropathy is another side effect of chemotherapy regimens. Loss of balance and loss of sensation in the hands and feet is a concern. Take measures to reduce risk of falls by removing area rugs, clear and place non-skid mats in the bathtub, and use nightlights. Larger pens with a wider circumference or with grippers can help to hold a pen when hands are weak.
5. Calm your nerves by using techniques such as deep breathing, meditation, and yoga which assists with lymphatic flow, pain, and are great stress relievers.
6. Conserve your energy by using carts to carry items instead of making several trips to the refrigerator when cooking. Use frozen vegetables instead of fresh to avoid the work of chopping. Sit while you perform tasks. Store items that you need regularly nearby.
7. Try to use both hands as a team rather than relying just on the unaffected arm for daily tasks such as bed making, dishwashing or lifting. If you recently received surgery, it is better to slide objects if possible rather than lifting them.
8. Finger fitness is important if chemotherapy has caused weakness. Special exercises can help you to maintain or improve the dexterity and strength in your hands.
9. Short rest breaks of 5-10 minutes during every 30-40 minutes of task can help to conserve energy for more enjoyable activities.
10. Velcro is one of the greatest inventions. Find shoes that use Velcro if unable to tie shoelaces.

The most common issues that plague post-mastectomy patients are upper-crossed syndrome and range of motion limitations in the affected shoulder. Upper cross syndrome is the combination of protracted (rounded) shoulders, forward head, cervical lordosis, winged-scapula, and thoracic kyphosis. As a result of these postural deviations, mastectomy, lymph node dissection, and/or radiation, the chest muscles may become tight, shortened and spastic. This not only exacerbates the postural deviations, but may limit the ability of the patient to move their arm/shoulder through flexion, extension, abduction, and external rotation. While this is a general statement, the majority of patients will present with these symptoms. This is compounded even more if the woman undergoes reconstructive surgery. Not only with it further exacerbate upper-crossed syndrome, it will create a muscle imbalance in the area of surgery, if either the rectus abdominis or latissimus muscle are used for reconstruction.
The most important factor in the safety and efficacy of the exercise program is the initial assessment. At the very least this should include a comprehensive postural assessment as well as shoulder range of motion measurements taken with a goniometer. The well-trained fitness professional will be able to deduce, from the results, which muscles need to be stretched and which need to be strengthened. By selecting the wrong combinations of exercises, the results may not only be undesirable, they may in fact be detrimental. For example, if a client presents with moderate to severe upper-crossed syndrome, performing any kind of “pushing” exercise that would involve the chest muscles (chest press), could make the syndrome even more pronounced by causing the pectoral muscles to tighten and contract. Instead, the goal need to be on stretching the chest wall and strengthening the opposing muscles in the back; particularly the scapular stabilizers.
Prior to adding a load (resistance) of any kind, the patient should have close to full range of motion through the particular plane of motion. Without correcting the range of motion first, the patient will reinforce the negative movement pattern by performing strength training exercises throughout a limited pattern of movement. Therefore, initially the focus should be on range of motion exercises. These may include very basic exercises that the patient can do on their own; front wall walks, side wall walks, pendulum swings, and corner stretch, or active isolated stretching that can be executed with the assistance of a professional. The combination of both will increase the speed of improvement in most cases.
Once close to full range of motion is achieved, the emphasis can be on strength training. Not only will this help to correct the postural and range of motion deviations, it will help increase bone density and lean muscle mass. Many women will either be of menopausal age, or thrown into menopause from their cancer treatment. With estrogen no longer being produced, the risk of osteoporosis increases. To make things even more complicated, the long-term side-effects of chemotherapy include osteoporosis, diabetes, and damage to the heart and lungs; all of which can be avoided or improved through proper exercise recommendations.
The last part of the equation is the risk of lymphedema of the affected arm/shoulder. Lymphedema is the swelling of the extremity following the removal of, or radiation to the lymph nodes on that side. Even if someone has undergone a sentinel node biopsy, and only had one node removed, they can still get lymphedema. Lymphedema is progressive if untreated and can be very painful and disfiguring. It can happen at ANY time after surgery; one hour or fifty years. The risk doesn’t increase or decrease with time, however a higher percentage of body fat, infection, age, and poor nutrition can all increase the risk once someone is at risk. In my sixteen years of working with cancer patients, I would say this is the number one “overlooked” issue amongst cancer patients. More often than not, they will not even be told about lymphedema. Following lymph node dissection and/or radiation, the lymphatic pathways do not operate with the same efficacy that they did previously. Therefore, we no longer know what the individuals exercise threshold is. It is critical to START and PROGRESS SLOWLY. This allows for a gradual increase in frequency, intensity, and duration of the exercise program. If at any point there is swelling, the patient should be advised to stop exercising and see their doctor immediately to determine if, in fact, they do have the onset of lymphedema. They should come back with a medical clearance form and the exercise instructor should take a step back with the frequency, intensity, and duration to the point prior to the onset of swelling.
Putting all of these pieces together is very much like solving a mathematical equation. If you are missing any of the information, you will never solve the problem. A typical exercise session should begin with cardiovascular exercise. This too should be gradually increased at a rate that the client is comfortable with and their body responds favorably to. They should stay well-hydrated, they should not wear tight-fitting or restrictive clothing on their upper body, and they should not overheat (all of these factors can increase the risk of lymphedema). Following the warm-up they should be instructed to do a series of lymph drainage exercise to open up the lymphatic pathways and prepare the body for exercise. I reference these exercises in CETI’s Cancer Exercise Specialist Handbook and Breast Cancer Recovery with the BOSU® Balance Trainer Book.
Following the warm-up and lymph drainage exercises, the exercise specialist should determine what the areas of “need” are for the client. Remember to begin with stretching and range of motion exercises until they have close to “normal” range of motion. At that point the goal becomes strength training and choosing exercises that will strengthen the weaker muscles and stretch the tight and shortened muscles. Weight/resistance should also be very gradually increased and attention paid to any potential swelling of the extremity. Typically I chose exercises that will stretch the chest (chest fly, corner or door stretch, assisted stretching) and will strengthen the back (low/high rows, reverse flies, lat pulldown). They often [present with winged scapula following a node dissection. If this is the case, I will incorporate exercises that will strengthen the serratus anterior. If they have undergone an abdominal TRAM procedure, core work will be of the greatest importance in preventing, or minimizing, low back pain.
Because every muscle in the body works synergistically, an imbalance in the shoulder can lead to a multitude of imbalances from the hips to the knees to the ankles etc… Choose your exercises carefully. Put emphasis on the areas of need. This is not and can never be a cookie-cutter workout. No two breast cancer patients are the same. Not only are you taking into consideration their surgery, reconstruction, and treatment, you have to also factor in the remainder of their health history and any additional orthopedic concerns. I urge anyone who wants to work with cancer patients to undergo specialized training. It is very complex and the untrained professional can end up doing more harm than good.

Cancer surgery and treatment often results in survivors suffering debilitating physical impairments. These can often be ameliorated by a good exercise program that has the added benefit of helping survivors to engage in those activities in which they participated prior to their diagnosis. This article addresses some of the physical side effects cancer survivors may face, including lymphedema and a series of safe and effective techniques to restore functional fitness for those with or at risk for lymphedema.
Surgery, chemotherapy, radiation, and hormonal therapy have side effects, which exacerbate the problems faced by cancer patients. Surgery can create adhesions that can limit range of motion, and cause pain, numbness and tightness. Removal of lymph nodes creates scars and may decrease range of motion. Radiation can cause fatigue, tightness and stiffness. It also can increase the risk of developing lymphedema. Chemotherapy may affect balance, a patient’s immune system, and cause neuropathy, fatigue, sarcopenia, and anemia. Hormonal therapy can cause joint pain and early menopause and the side effects associated with menopause.
Before beginning a cancer exercise program, a patient must receive medical clearance. A medical history, base line range of motion and girth measurements, and a general fitness assessment are taken. It is important to note that many exercises and movements may be contraindicated based on a person’s fitness assessment, medical conditions, and particular surgery. There are different exercises necessary for each type of reconstruction. For those who were active prior to surgery it is imperative to slowly work back up to the previous level of activity. It is not wise to go back to a gym and immediately continue with a pre-cancer exercise routine.
Research has shown that exercise is safe for cancer survivors, even those with or who are at risk for lymphedema. Dr. Schmitz stresses the importance of starting slowly and using proper form with a well trained certified professional. Her study demonstrates the importance of exercise after cancer with slow progressive improvement in order to decrease risk of lymphedema. The research shows that breast cancer survivors no longer have to give up activities that they enjoy doing and avoid activities of daily living. Aerobic exercise is essential to good health and we advise a patient to walk as much as possible. Initially, one might start by walking around their house or up and down their block and then slowly increasing the distance walked. Many physicians recommend that their patients try to walk during chemotherapy. This may decrease fatigue. If using aerobic equipment, make sure not to grip on the railing.
Unfortunately, there is no way to know which patients with lymph node dissection will get lymphedema. This makes it imperative to follow the established guidelines and take a prudent approach to exercise. Patients who have lymphedema need to progress slowly and use a properly fitted garment. Our goal is to promote physical activity without exacerbating lymphedema. Severe range of motion issues and cording problems are referred to lymphedema specialists. Moreover, measurement of the limbs that are at risk for lymphedema are performed frequently to make sure they have not changed in size. Symptoms can be managed easier if they are addressed promptly. Progress is monitored in order to make appropriate modifications to a patient’s program. It is important to learn the right exercises for a patient’s particular situation and how to do them properly and with good form. The patient should learn which exercises to perform, the sequencing, and quantity of repetitions. Exercise smartly and under professional guidance!
Lymphedema can be debilitating and painful and can affect the emotional health of the patient. Our bodies work better if engaged in regular physical activity, but it must be done in a safe manner if lymph nodes have been removed or radiated. A cancer fitness program for someone with lymphedema should begin as an individualized program. The patient must be supervised to make sure there are no subtle volume changes to the limb. Ultimately, we want a patient to be able to exercise on his or her own.
The starting point is a low impact exercise program, performing range of motion stretches and techniques to improve venous drainage. First, we elevate the affected area above heart level. Over time, stretches are incorporated until a patient can achieve 80% of range of motion. At that point, we start adding strength training. A stretching program for those with upper body lymphedema begins with moving or stretching the neck and shoulder areas. If a patient is still healing from breast cancer surgery, begin with pendulum arm swings. The arm is then moved and stretched in all directions, going across the chest and behind the head and back. Stretches that move the arms in shoulder flexion, extension, abduction, and adduction are added. Finally internal and external rotations are addressed. Patients suffering from fatigue can perform many of the stretches while in bed. An easy-to-follow DVD is Recovery Fitness Simple Stretching, which can be found on www.recoveryfitness.net.
All of the exercises incorporate abdominal breathing, which can stimulate lymphatic drainage. This intra-abdominal pressure may help move sluggish lymph fluid, stimulate lymph flow, and act as a lymphatic system pump. This type of breathing enables oxygen to get to the tissues. Abdominal breathing and relaxation breathing, along with the proper exercises can also reduce stress, a common cancer side effect. If weak, it may be best just to stretch and breathe deeply.
Strength training may help pump the lymph fluid away from the affected limb. Exercise helps the lymphatic fluid to April / June 2013 ~ NATIONAL LYMPHEDEMA NETWORK 13 move. Muscles pump and push the lymph fluid and can help move the lymph from the affected area. Strength training may also strengthen the arm so that it can handle those activities that may have otherwise led to swelling with a greater level of ease. Always wear a sleeve and stop if there is swelling or pain. Start with light weights and slowly increase repetitions and eventually weight.
Cancer survivors should follow a systematic and progressive plan. Exercise starts with a warm-up and cool down. Begin with deep breathing. Keeping a strong core should be emphasized. It is important to remember that following treatment the body may have become weaker. Even if a patient had exercised using 10 pound weights before surgery, if one is at risk for lymphedema they must start with a light weight. We teach patients to always listen to their bodies and to stop if they feel tired or if their limb aches or feels heavy. Patients must be aware of any changes in their body.
Progression of exercise should be gradual. A deconditioned person should start without using any weight and concentrate on proper technique. If 8-10 repetitions can not be executed, repetitions should be decreased or the weight lowered or resistance band used changed to less resistance. The exercise routines have to be adapted for the day-to-day changes that that can affect the ability to work out. Our program will start using a very light weight, with few repetitions, typically 10. In subsequent sessions, patients can add repetitions. After performing 2 sets of 10 repetitions with no problem then a small amount of weight may be added in 1 pound increments. We also alternate between a strength training exercises with a stretch for each muscle group and to alternate an upper body and lower body exercises. Pilates exercises are great way to incorporate deep breathing with strengthening the core. The deep breathing helps to pump lymphatic fluid and will also help reduce stress.
Every patient is unique. Many patients have pre-existing medical issues. The exercise program should be modified to accommodate all body types and needs. Some might need pillows for comport or postural problems. Also if osteoporosis is an issue, a cancer therapist should have experience working with this population. Always monitor the affected limb. Look for feelings of fullness or aching. We do not want to overwhelm the lymphatic system. Drink plenty of water and stop immediately if any pain. Lymphedema patients should elevate their limbs after a session.
Learn which aerobic exercises are considered safe. Walking, biking, and swimming are considered very safe. Hot tubs, pools, and warm lakes may increase risk of infection. In choosing an activity, consider the risk of injury, prior medical condition, and fitness level. Injuries can create further complications for those with lymphedema. It is still unclear whether certain sports can be safe. For example, tennis can put a lot of stress or repetitive activity on one’s limbs. It is important to know if the activity was something performed prior to lymphedema. If the patient wants to resume the activity in order to exercise, have fun, and to have good quality of life, a sports fitness program can be instituted. This should be performed under medical guidance. In a sports fitness program, the muscles used in the sport are progressively strengthened so that the sport can be resumed. Patients must use caution as they return to a sport.
One of the most important things that can be done to decrease the risk of lymphedema is to keep weight at a good level. Those individuals with whom I have worked who have had lymphedema typically see a marked reduction of swelling in conjunction with weight loss. My students who are successful in losing weight have the most success in lymphedema control. Proper nutrition is important and decrease salt intake. Evidence suggests numerous benefits of exercise: improved fitness level, physical performance, quality of life, and less depression and fatigue. Exercise is part of a healthy lifestyle and will help in weight control and emotional health. There are exercise programs that are targeted at cancer survivors but not all of them will meet the needs of someone at risk for lymphedema.
My goal is for cancer survivors to participate in individually structured and group exercise programs at all cancer centers or facilities close to their homes.

Breast cancer — two words that strike fear in every woman. The good news is women can help lessen their risk. One important defense is to consume a high fiber diet.
A 2011 meta-analysis of 10 scientific studies found that higher fiber intake is associated with lower risk of breast cancer.1 In 2012, another meta-analysis of 16 studies came to the same conclusion.2 In the Nurses’ Health Study, higher fiber intake during childhood and adolescence was linked to a decrease in the risk of breast cancer in adulthood.3
How fiber impacts breast cancer risk
Given that animal products, refined grains, sugars and oils contain little or no fiber, fiber intake is a marker for greater intake of natural plant foods, many of which are known to have a variety of anti-cancer phytochemicals. Some breast cancer protective substances that have already been discovered include isothiocyanates from cruciferous vegetables4, organosulfur compounds from onions and garlic,5 aromatase inhibitors from mushrooms,6 flavonoids from berries,7,8 lignans from flax, chia and sesame seeds,9 and inositol pentakisphosphate (an angiogenesis inhibitor) from beans.10
Influence of fiber, glucose, insulin on breast cancer
High-fiber foods help to slow emptying of the stomach and absorption of sugars, which decreases the after-meal elevation in glucose. This is meaningful because elevated glucose levels lead to elevated insulin levels, which can send pro-cancer growth signals throughout the body, for example via insulin-like growth factor 1 (IGF-1).11 As such, high dietary glycemic index and glycemic load (characteristic of refined grains and processed foods) are associated with an increase in breast cancer risk.12-14 Accordingly, a study on Korean women found that higher white rice intake was associated with higher breast cancer risk.15
Fiber, estrogen, and breast cancer
Increased exposure to estrogen is known to increase breast cancer risk.16-18 A woman may be exposed to estrogen via her ovaries’ own production, estrogen production by excess fat tissue, or environmental sources such as endocrine-disrupting chemicals (like BPA, a chemical added to many consumer products). Fiber can reduce circulating estrogen levels, thereby reducing breast cancer risk, because it helps to remove excess estrogen from the body via the digestive tract. Fiber binds up estrogen in the digestive tract, accelerates its removal, and prevents it from being reabsorbed into the body.19-21
In addition, soluble fiber (as shown in studies using prunes and flaxseed) seems to alter estrogen metabolism so that a less dangerous form of estrogen is produced, whereas insoluble fiber (wheat bran) did not have the same effect. 22,23 For this reason, beans, oats, chia seeds and flaxseeds may provide some extra protection due to their high soluble fiber content.
Foods rich in fiber
Although most people probably just associate whole grains with fiber, beans contain more fiber than whole grains, and vegetables and fruits (and some seeds) contain comparable amounts – here are a few examples:
- 1 cup cooked quinoa – 5 grams fiber
- 1 cup cooked brown rice – 4 grams fiber
- 1 cup cooked kidney beans – 11 grams fiber
- 1 cup cooked broccoli – 6 grams fiber
- 1 cup blueberries – 4 grams fiber
- 1 tablespoon chia seeds – 6 grams fiber
Overall benefits of fiber: promotes weight loss and digestive health
Fiber, by definition, is resistant to digestion in the human small intestine. This means that during the digestive process, fiber arrives at the large intestine still intact. Fiber takes up space in the stomach but does not provide absorbable calories, and it also slows the emptying of the stomach.24 These properties of fiber make meals more satiating, slow the rise in blood glucose after eating and promote weight loss. In the colon, fiber adds bulk and accelerates movement, factors that are beneficial for colon health. Soluble fiber (primarily from legumes and oats) is effective at removing cholesterol via the digestive tract, resulting in lower blood cholesterol levels. Some types of fiber are fermented by intestinal bacteria. The fermentation products, short-chain fatty acids (SCFA) such as butyrate and propionate, have anti-cancer effects in the colon and also serve as energy sources for colonic cells. These SCFA are also thought to contribute to promoting insulin sensitivity and a healthy weight.25,26
Fermentable fiber also acts as a prebiotic in the colon, promoting the growth of beneficial bacteria. Fiber intake is associated with a multitude of health benefits, including healthy blood pressure levels and reduced risk of diabetes, heart disease and some cancers.24,27
Importance of choosing high-fiber and high-nutrient foods
Yes, fiber itself has some breast cancer-protective properties, like limiting glycemic effects of foods and assisting in estrogen removal, but we get optimal protection when we focus on foods that are both rich in fiber and rich in micronutrients and phytochemicals.
G-BOMBS contain fiber along with numerous anti-cancer phytochemicals, however, green (cruciferous) vegetables, mushrooms, flax and chia seeds in particular contain anti-estrogenic substances in addition to fiber, making them more effective breast cancer fighters than whole grains. Remember, beans are higher in fiber (and resistant starch) and lower in glycemic load than whole grains, making beans a better carbohydrate choice.
A Nutritarian diet is designed to include a full portfolio of the most protective foods to prevent cancer and slow the aging process. Advances in nutritional science make winning the war against cancer a reality in our lifetime.

What are some things you can do to help your client recover and thrive after Breast Cancer treatment? What are important things to know to work with BC clients…
Once a virtual death sentence, cancer today is a curable disease for many and a chronic illness for most. With continued advances in strategies to detect cancer early and treat it effectively along with the aging of the population, the number of individuals living years beyond a cancer diagnosis can be expected to continue to increase.
Approximately 15.5 million Americans in the United States are cancer survivors. By 2026 that number is expected to reach 20 million. Anyone who has been diagnosed with cancer, from the time of diagnosis through the rest of his or her life is considered a cancer survivor. And while not all cancer survivors are older adults, many are simply because of the cumulative effect of years of lifestyle issues that are risk factors for their disease. Survivors less than or equal to 19 years old comprise 1% of the cancer survivor population, 6% of survivors are aged 20–39 years, 33% are aged 40–64 years and 60% (more than half) are aged greater than or equal to 65 years.
Breast cancer survivors are the largest constituent group within the overall population of cancer survivors (22%), followed by prostate cancer survivors (19%) and colorectal cancer survivors (11%) (3). Gynecological and other genitourinary cancers each account for 9% of cancer survivors, followed by hematological cancers and lymphoma (7%) and lung cancer (4%). Other cancer sites account for much smaller percentages and together are responsible for 19% of the total number of survivors. In terms of stratification by gender, more than two thirds (69%) of all female cancer survivors have a history of breast (41%), gynecological (17%) or colorectal (11%) cancer. For male survivors, two thirds (66%) have a history of prostate (39%), other genitourinary (such as testicular or renal) (14%) or colorectal (13%) cancer.
Not surprisingly, cancer survivors are often highly motivated to learn more about things like nutrition, supplements and herbal remedies, and exercise that might improve treatment outcomes and ultimately their survival and quality of life. For many of the most important nutrition and physical activity questions faced by cancer survivors, the scientific evidence comes only from observational and laboratory animal data, or unreliable reports from poorly designed clinical studies. Moreover, the findings from these studies are often contradictory. Very few controlled clinical trials have been done to test the impact of diet, nutritional supplements or nutritional complementary methods on cancer outcomes among cancer survivors.
In an effort to identify and evaluate the scientific evidence related to optimal nutrition and physical activity after the diagnosis of cancer, the American Cancer Society (ACS) convened a group of experts in nutrition, physical activity and cancer. The findings of this group guide healthcare providers, cancer survivors and their families through the mass of information and help them make informed choices related to diet and exercise. The Expert Committee reviewed all of the scientific evidence and best clinical practices for different types of cancer and “graded” both the quality and certainty of the scientific evidence for factors affecting the most common cancers. As was already mentioned, there are few clear answers to many questions, a wide range of sources and often conflicting information. But, these experts agree that even when the scientific evidence is incomplete, reasonable conclusions can be made that can help to guide choices in the areas of nutrition and physical activity.
Physical activity may help cancer patients build up their physical condition; decrease the number of comorbid conditions (like heart disease and diabetes); reduce drug interactions; help cancer patients cope with treatment; restore good health; improve quality of life during and after treatment; and help cancer patients and survivors maintain independence as long as possible
Physical rehabilitation programs similar to those for cardiac rehabilitation may be effective in managing, controlling or preventing adverse medical and psychosocial outcomes manifested during cancer survivorship. For example, exercise programs are being developed as interventions to improve the physical functioning of persons who have problems with mobility as a result of therapy and are also being shown to be efficacious for weight control after breast cancer treatment, lessen the effects of chronic fatigue, improve quality of life, prevent or control osteoporosis as a result of premature menopause and prevent or control future or concurrent comorbidities.
Diet, weight and physical activity interventions carry tremendous potential to affect length and quality of survival in a positive manner and prevent or control morbidity associated with cancer or its treatment.
General Physical Activity Guidelines for Cancer Survivors
In general, physical activity is likely to be beneficial for most cancer survivors. Recommendations on the type, frequency, duration and intensity of exercise should be individualized to the survivor’s age, previous fitness activities, type of cancer, stage of treatment, type of therapy, and comorbid conditions.
Particular issues for cancer survivors may affect or contraindicate their ability to exercise. Effects of their cancer treatment may also promote the risk for exercise-related injuries and other adverse effects.
The following specific precautions are from the American Cancer Society:
- Survivors with severe anemia should delay exercise, other than activities of daily living, until the anemia is improved.
- Survivors with compromised immune function should avoid public gyms and other public places until their white blood cell counts return to safe levels.
- Survivors who have completed a bone marrow transplant are usually advised to avoid exposure to public places with risk for microbial contamination, such as gyms, for 1 year after transplantation.
- Survivors suffering from severe fatigue from their therapy may not feel up to an exercise program, so they may be encouraged to do 10 minutes of stretching exercises daily.
- Survivors undergoing radiation should avoid chlorine exposure to irradiated skin (e.g., swimming pools and whirlpools).
- Survivors with indwelling catheters should avoid water or other microbial exposures that may result in infections, as well as resistance training of muscles in the area of the catheter to avoid dislodgment.
- Survivors with significant peripheral neuropathies may have a reduced ability to perform exercises that use the affected limbs because of weakness or loss of balance. They may do better with a stationary reclining bicycle, for example, than walking outdoors.
For the general population, the ACS and other health organizations recommend at least 30 minutes of moderate physical activity at least 5 days per week to reduce the risk for cancer, cardiovascular disease and diabetes. These levels of activity have not been studied or tested specifically in cancer survivors, however. For the general population and for cancer survivors, any movement is likely beneficial. Therefore, although daily and regular activity may be preferred and may be a goal, any steps that are taken to move from a sedentary to an active lifestyle should be encouraged. For survivors wanting maximum benefit, the message should be that the health benefits of exercise are generally linear, with benefit related to higher intensity and duration, although extremely high levels of exercise might increase the risk for infections.
