Melanoma is the most deadly form of skin cancer. It evolves from the pigment producing cells of the skin and can occur on any part of the skin surface, the mucous membranes, or the eye. If caught and treated early, cure rates are high and survival over time is good. However, left untreated, melanoma spreads or metastasizes to other parts of the body much more frequently than other types of skin cancer.
Basal Cell and Squamous Cell Carcinoma
Basal cell carcinoma is the most common type of skin cancer. Basal cell is usually caused by sun exposure including both increased cumulative sun exposure and occasional intense sun exposure. This type of skin cancer can appear as a shiny bump or nodule, an open sore that bleeds and crusts, a pink bump with rolled edges and a central indentation, or a white scar-like area.
