Hi, Thanks for writing in. It is possible that after getting wound, the skin has not healed in a proper way. It happens only in some people and this can give rise to a cancer. Cancer is a difficult disease to treat and requires close monitoring. Unfortunately you have developed a second cancer in the same location where you had it the first time. The treatment is usually complete excision and skin grafting if required. This is followed by chemotherapy and radiation depending on the pathological aggressiveness and biopsy results. You might be having a more aggressive type of cancer which requires intensive treatment to prevent it form spreading to adjacent areas. Wishing you a quick recovery. Please do not worry.
