Stages of melanoma skin cancer

Staging is a way of describing or classifying a cancer based on the extent of cancer in the body. Staging is commonly used to plan treatment. The most common staging system for melanoma is the TNM system. Melanoma is also put into stage groupings (0,1,2,3,4) based on TNM.

Melanoma cancer cells have the potential to spread from the skin to other parts of the body where they can grow into new tumours. This process is called metastasis. The tumours are also called metastasis (singular) or metastases (plural).

Prognosis and survival for melanoma skin cancer

Prognosis for melanoma depends on the thickness of the tumour and how fast the cells are growing.
