Although surgery is the most commonly used therapy for skin cancer, other treatments include radiation therapy and chemotherapy. The most recent intervention, however, is immunotherapy which involves stimulation of the patient's white blood cells to kill the cancer. Recent reports from the National Cancer Institute indicate that immunotherapy does have potential for the most deadly skin cancer, melanoma. The most common skin cancer is basal cell carcinoma, followed by squamous cell carcinoma. Imiquimod (Aldara), a topical cream, is currently FDA approved to treat basal cell carcinoma and actinic keratoses.  If you think you may have skin cancer (e.g. a new growth or one bleeding easily or forming an ulcer or changing in size, shape, color, or any other change), call your dermatologist for an appointment
