Melanoma stages

Making an educated treatment decision begins with the stage, or progression, of the disease. The stage of melanoma is one of the most important factors in evaluating treatment options.

Our cancer doctors use a variety of diagnostic tests to evaluate melanoma and develop an individualized treatment plan. If you have been recently diagnosed, we will review your pathology to confirm you have received the correct diagnosis and staging information, and develop a personalized treatment plan. If you have a recurrence, we will perform comprehensive testing and identify a treatment approach that is suited to your needs.

Melanoma stages are assigned based on the size or thickness of the tumor, whether or not it has spread to the lymph nodes or other organs, and certain other characteristics, such as growth rate.

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.
