There are many different kinds of tumors that can grow on the feet or ankles, but there are certain types we treat more often at Fixing Feet Institute: ganglion cysts, vascular tumors, and fatty tumors.
Ganglion cysts can technically pop up anywhere on the body, but they are most common on the hands and feet. They are benign and are a lump of cells that are knotted together and grow beneath the surface of the skin. The cysts can appear on the top or bottom of the foot, but since they are benign, they are more uncomfortable than they are dangerous.
These tumors can be benign or cancerous, and again, are not always just found on the feet. A type of vascular tumor that is often found on the base of the foot is a glomus tumor; they are rare, but benign. They are more common in women and individuals in their 40s and 50s and are characterized by a sensitivity to cold, localized tenderness, and severe intermittent pain.
Lipomas are growths of fat cells usually found just below the skin. They can be found anywhere, but when it comes to feet they are normally on the bottom of the foot. Lipomas are the most common noncancerous soft tissue growth. The tumors are usually pretty small and almost rubbery feeling. They should not be painful and they grow very slowly.
The word "tumor" is so often associated with cancer, that many people forget that many tumors can be benign. If you suspect you have a tumor, it's very important to visit your doctor right away so he they can examine it to be sure it is not cancerous. Remember to keep an eye out for any unusual growths that seem to be on the skin (rather than under it) as well: skin cancer can turn up anywhere, including the feet.
