There are four stages of melanoma based on its progression. Stage 0 is the initial stage, where the cancer is only found in the skins top layer and can be treated and removed with surgery. Stages I and II often necessitate wide excision surgery; in both cases, cancer has not yet reached the lymph nodes. In stage III, cancer spreads to the nearby lymph nodes and is treated through wide excision of the primary tumor along with lymph node dissection. The IVth and final stage is when cancer has metastasized to other parts of the body and may be treated by surgery or radiation therapy (12).
