There are three main types of skin cancer: squamous cell carcinoma, basal cell carcinoma, and melanoma. There are also many other forms of skin cancer that are less common. Some are benign and other malignant, so it is important to ensure you have the proper diagnosis. Squamous cell carcinoma starts in the squamous cells that are located just below the outer surface of your skin. Basal cell carcinoma begins in the basal cells of the skin, which are located beneath the squamous cells. These cells are responsible for creating new skin cells. Melanoma is a cancer of that begins in the melanocytes, the cells that give your skin its color. Melanoma is the most aggressive and dangerous form of skin cancer. Merkel cell carcinoma is a rare type of skin cancer. It mainly affects older people who have a weakened immune system or who have had long-term exposure to the sun. Actinic keratosis is a change in skin cells that can lead to squamous cell carcinoma. It is often referred to as “pre-malignant”. Other types of skin cancer include Kaposi sarcoma, dermatofibrosarcoma, angiosarcoma, atypical fibroxanthoma, skin lymphoma and skin adnexal tumors. These types of skin cancer are very rare.
