Full Answer

The amount of healthy skin removed during a wide excision depends on the thickness of the melanoma, reports the American Cancer Society reports. If the melanoma is near lymph nodes the doctor may recommend a sentinel node biopsy after the surgery.

If the sentinel node indicates the cancer has spread, the doctor may surgically remove all the lymph nodes near the melanoma, as stated by the American Cancer Society. The doctor may also treat the patient with interferon after the surgery. Interferon is a medication that can kill any melanoma cells left in the body after surgery. Other medications being studied in clinical trials may also be administered.

Survival rates for stage 2 melanoma depends on whether it is type 2a or 2b, according to Healthline. As of 2015, the five-year survival rate is 81 percent for stage 2a and 70 percent for stage 2b. The 10-year survival rate is 67 percent for 2a and 57 percent for 2b.
