Prognosis of skin cancer will be determined of the type of skin cancer you have. Basal and squamous cell carcinomas have excellent prognosis. A simple incision is often the only thing needed for a cure.
The prognosis for melanoma will depend on the type of melanoma you have. Melanoma in situ, which is melanoma that is just in the epidermis has excellent prognosis. The five-year survival rate is greater than 95%.
Invasive melanoma is a little bit more difficult to understand. The prognosis will depend on how deep the melanoma has invaded, as well as whether lymph nodes are involved. Metastatic melanoma has the poorest prognosis of all types of melanoma. Depending on where the melanoma has spread, the mortality rate varies anywhere from 20% to 50%.
