Skin cancer is the most common type of cancer, with over 1 million new cases a year. Sun exposure and fair complexion are risk factors for skin cancer. There are three main types of skin cancer: basal cell carcinoma, squamous cell carcinoma, and melanoma. Any non-healing unusual growth should be evaluated to rule out skin cancer. Melanoma is the deadliest form of skin cancer, appearing typically as an abnormal or changing mole. The classic features of melanoma include asymmetric shape, irregular borders, uneven color, and enlarging diameter. Melanoma tends to spread to the lymph nodes and other organs, so early detection through regular skin screenings is crucial.
Treatment for skin cancer depends on the type, size and location of the tumor. Most options remove the entire growth and are usually effective. Removal procedures are usually simple and require only a local anesthetic in an outpatient setting.
