In their later stages, melanomas and other skin cancers can produce different signs and symptoms, including changes in color, size, or shape, as well as bleeding and pain. However, in their early stages, when they are most curable, skin cancers commonly have no symptoms, and their significant features may only be recognized by a highly knowledgeable dermatologic provider. Thus, patients who are at increased risk of developing skin cancers should have regular exams, ideally every six months but at least once a year, by a thorough and experienced professional.
