Skin cancer is the most commonly diagnosed form of cancer in humans. There are three main types of skin cancers: basal-cell skin cancer (BCC), squamous-cell skin cancer (SCC) and melanoma. The first two, along with a number of less common skin cancers, are known as nonmelanoma skin cancer (NMSC).
Cutaneous squamous-cell carcinoma is the second-most common cancer of the skin (after basal-cell carcinoma, but more common than melanoma). It usually occurs in areas exposed to the sun. Sunlight exposure and immunosuppression are risk factors for SCC of the skin, with chronic sun exposure being the strongest environmental risk factor.
Sunspots are small darkened areas on the skin, often on the face. Top derms explain the causes, ways to treat them and when to worry about skin cancer.
Melanoma is the most dangerous type of skin cancer; it develops from the melanin-producing cells known as melanocytes. It typically occurs in the skin, but may rarely occur in the mouth, intestines, or eye ( uveal melanoma ).
Excessive unprotected exposure to the sun's ultraviolet (UV) rays can cause skin damage, eye damage, immune suppression, and skin cancer. Even people in their 20s can develop skin cancer.
Skin Cancer: Recognition and Management is a clinical reference by Robert A. Schwartz covering skin and accessible mucosal disorders, premalignant and malignant cutaneous disorders, including melanoma, Kaposi's sarcoma and other sarcomas, cutaneous lymphoma, cutaneous metastatic disease and cutaneous markers of internal malignancy.
