What are the stages of melanoma skin cancer?

Malignant melanoma is staged in 5 different stages. There is stage 0, where the abnormal cells are located entirely within the epidermis. There are stages 1 and 2. Stage 1 is how deep the melanoma cells have gone and invaded into the dermis. Stage 2 is where they've invaded deeper and therefore are more aggressive. Stage 3 is where the cells are located in the lymph nodes or in certain sections of the skin. Stage 4 is where those cells have metastasised or travelled to other organs of the body including distant site of the skin, the lung, the brain, and other internal organs.
