Emed News Monday, November 16, 2009   What Causes Skin Cancer and its Effects? Skin Cancer Causes Ultraviolet (UV) light exposure, most commonly from sunlight, is overwhelmingly the most frequent cause of skin cancer. Other important causes of skin cancer include the following: Use of tanning booths Immunosuppression—impairment of the immune system, which protects the body from foreign entities, such as germs or substances that cause an allergic reaction. This may occur as a consequence of some diseases or can be due to medications prescribed to combat autoimmune diseases or prevent organ transplant rejection. Exposure to unusually high levels of x-rays Contact with certain chemicals—arsenic (miners, sheep shearers, and farmers), hydrocarbons in tar, oils, and soot (may cause squamous cell carcinoma) People who had at least one severe sunburn early in life have a greater risk of developing skin cancer. Treatment for basal cell carcinoma and squamous cell carcinoma is straightforward. Usually, surgical removal of the lesion is adequate. Malignant melanoma, however, may require several treatment methods, including surgery, radiation therapy, and chemotherapy.   posted by emedinfo @4:07 AM permanent link   | |    Bookmark & Share     << Home
