Cancer is defined as should there be an abnormal excessive development of any kind of tissue. So does or will cancer affect the foot? Certainly it will, as the foot has all the same tissues as other parts of the body. Cancer in the foot is really unusual, but when it does happen it has the potential to be very serious because it is frequently missed or misdiagnosed as somethng not so serious. There are two types of cancer which may impact the foot. The first is where the cancer arises in the foot, so this might 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 numerous things which could go wrong an extremely high index of suspicion is required to identify one of these primary cancers from what could be considered a regular and common foot problem. This is why the competence of a good knowledgeable clinician is needed to manage foot problems and to exclude one of these more probably serious ailments that are uncommon. The other kind of cancer that can affect the foot is a metastasis or a spread of the cancer coming from another area of the body. This cancer could possibly be already be recognized and may spread to the foot where it produces pain in the foot. On the other hand the cancer may start growing in another organ in the body and it is un-diagnosed there and it sends a metastasis or propagates to the foot and results in pain in the foot. This is very unusual but when it does happen it is quite serious because it normally implies that the original cancer is well established. It also presents a diagnostic problem for the clinician who is seeking to diagnose the real reason for the pain in the foot. Again, a really high index of suspicion and instinct is required by the clinician to pick this up in the first stages. The sooner that these kinds of cancers are identified the better the end result will probably be.
