How will a doctor determine whether I have skin cancer?
To diagnose cancer, your doctor will perform a biopsy. An incisional or excisional biopsy is usually recommended to remove suspected melanomas. An incisional biopsy removes a portion of the tumor, whereas an excisional biopsy removes the entire tumor. A pathologist will examine the tissue under a microscope to determine whether cancer is present. A biopsy is the only definitive way to diagnose cancer. It can determine the type of cancer as well as the stage (how far the cancer has spread). Based on the biopsy, your doctor will be able to plan necessary treatment for your cancer.

How will my treatment be determined?
A number of factors will help your doctors determine the best treatment for your skin cancer. If it is non-melanoma, treatment typically involves removal of the growth through simple excision, freezing or burning of the tissue. For melanoma, the treatment may be more involved. The growth will be removed to help keep the cancer from spreading. If the cancer has already spread, you may need additional treatment, involving chemotherapy, radiation therapy or biological therapy. Your treatment will depend on the type and size of cancer, as well as other factors.

Am I at greater risk for skin cancer in the future?
It is even more important for you to protect yourself from the sun once you have been diagnosed with skin cancer. The areas that have been treated may be more sensitive to the sun, and you may be more susceptible to further skin damage. Everyone should take preventive measures against skin cancer. The Occupational Safety and Health Administration (OSHA) recommends wearing protective clothing in the sun, using sunscreen regularly and avoiding exposure during peak midday hours. In addition, some medications can increase your sensitivity to sunlight. If you are taking such a medication, you are at greater risk for sunburn and other skin damage. You should consult with a doctor about your medications and sun sensitivity.
