Types of Melanoma Skin Cancer
Four basic types of melanoma skin cancer appear on the top layer of the skin or penetrate below the skin's surface. These are easy to diagnose. The surface forms of melanomas may only attack the skin, while others are aggressive from the time of their diagnosis. However, rare forms of melanoma skin cancer manifest themselves in atypical body parts such as the eyes and organs.
