Full Answer

The cancerous mole also has an irregular border, explains the American Academy of Dermatology. It changes in size, shape or color or all three over time. Melanoma is the most dangerous type of skin cancer, notes to the Skin Cancer Foundation. In melanoma, the cancer arises from melanocytes, which contain pigments that give color to the moles and the skin. The melanocytes are found in the lowest level of the epidermis, which is the top layer of skin.

Like most skin cancers, melanoma is curable if it is found and treated in its early stages, says the Skin Cancer Foundation. If it is not treated, melanoma can spread very quickly and metastasize to distant sites in the body. By then, it is very difficult to treat and can be life-threatening. Over 135,000 cases of melanoma are diagnosed in the United States every year, and as of 2015, close to 74,000 of those cases are invasive.
