Skin cancer is the most common type of cancer with over one million new cases diagnosed every year. If left untreated, skin cancer may become dangerous, but with early detection and treatment, it is usually easily treatable. Skin cancer is commonly caused from sun exposure; therefore, people with fair skin, light hair or light eyes are at greatest risk for developing skin cancer. The three most common types of skin cancer are Basal Cell Carcinoma, Squamous Cell Carcinoma, and Malignant Melanoma.
