Yes. Just remember that less than 1% of the primary sources of cancer come from the feet. Occasionally we do see conditions such as Kaposi's Sarcoma or multiple myeloma in the foot but those cases are pretty few and far between. I've been a practicing podiatrist for twenty years and have only seen two cases. If you have a question be sure to have it checked by someone qualified in foot care. Cancer of the foot is rare, but put your mind at ease by having it checked.
