Colorectal cancer is the second-leading cause of cancer deaths in the United States, but it takes 30 years or longer to develop, as polyps grow on your colon wall and slowly morph into tumors. It's only during the last few years of that period that it's lethal and capable of spreading, reports Yahoo! Health.
But, this type of cancer is highly preventable, with drinking more milk or increasing dairy product consumption easy ways to reduce your odds of getting this disease. Researchers note strong (but not definitive) evidence of a link between milk’s vitamin D and reduced cancer risk. Plus, calcium may reduce precancerous polyps.
Other helpful hints include an active lifestyle and aspirin usage.
