Cancer is defined as if you have an abnormal excessive development of any kind of tissue. So does or could cancer affect the foot? Of course it does, as the foot has all the same tissues as other areas of the body. Cancer in the foot is pretty unusual, but when it does happen it has got the potential to be very serious since it is often missed or misdiagnosed as somethng not too severe. There's two types of cancer that might affect the foot. The first is where the cancer arises in the foot, so this may be in the any tissue from the skin to the bone to joint or the ligaments to the nerves or the blood vessels. For the reason that foot is a weight-bearing part of the body and has a lot of things that might go wrong a really high index of suspicion is required to identify one of these primary cancers from what could be thought to be a regular and frequent foot condition. That's the reason the experience of a good experienced clinician is required to manage foot disorders and to exclude one of these more potentially critical ailments that are unusual.
The other kind of cancer which may affect the foot is a metastasis or a spread of the cancer from another area of the body. This cancer could be already be clinically diagnosed and can spread to the foot where it produces pain in the foot. On the other hand the cancer may begin growing in a different organ in the body and it is un-diagnosed there and it sends a metastasis or propagates to the foot to cause pain in the foot. This is very unusual but when it can happen it is very serious since it normally signifies that the first cancer is well established. It also creates a diagnostic problem for the clinician who is attempting to diagnose the explanation for the pain in the foot. Again, a very high index of suspicion and intuition is needed by the clinician to pick this up in the early stages. The earlier that these kinds of cancers are diagnosed the better the outcome is likely to be.
