With the summer approaching quickly here in Phoenix, there is a real need to talk about the risks of too much sun. Overexposure to sunrays have many people concerned about developing skin cancer, specifically melanoma. This type of cancer is less common but a more serious type of skin cancer. Melanoma is a malignant (or cancerous) tumor of melanocytes which produce dark pigment in the skin called melanin. If this form of cancer is not found in its early stages, the outlook for patients with melanoma is not good – nearly 75% of all deaths from skin cancer occur in melanoma patients.
