Stage II melanoma
Stage II melanoma means the cancer cells have grown deeper into the skin, or have more high-risk features, but have not spread to the lymph nodes or beyond.
- Stage IIA: The cancer cells have grown 1-2 mm deep into the skin, and the tumor appears ulcerated, OR the cancer is 2-4 mm deep but is not ulcerated.
- Stage IIB: The cancer is 2-4 mm thick with ulceration, OR thicker than 4 mm but not ulcerated.
- Stage IIC: The cancer is more than 4 mm thick, and it is ulcerated.
