The three most common skin cancers include: Basal Cell Carcinoma, Squamous Cell Carcinoma and Melanomas. Basal Cell Carcinoma is the most common cancer known. It is also one of the easiest to spot and treat. Squamous Cell Carcinoma is the second most common skin cancer and Melanoma the third. Despite Melanoma being the third most common form of skin cancer, it is the most deadly, accounting for 75% of all skin cancer deaths. Therefore, an annual skin check by a dermatologist and a monthly skin check by you is vital to good skin care. When these skin cancers are detected, early treatment often result in cure. Be sure to make an annual skin check appointment.
