Melanoma is the most serious type of skin cancer. Melanoma occurs when the pigment-producing cells that give color to the skin become cancerous. The exact cause of all melanomas isn’t clear, but exposure to ultraviolet (UV) radiation from sunlight or tanning lamps and beds increases your risk of developing melanoma. Other risk factors include fair skin, a history of sunburn, having many moles or unusual moles, and a family history of melanoma. The risk of melanoma seems to be increasing in people under 40, especially women, The first signs and symptoms of melanoma include a change in an existing mole and the development of a new pigmented or unusual-looking growth on the skin. It is important to examine your skin regularly for new skin growth or changes, as well as getting a yearly skin cancer screening by a Dermatology healthcare provider.
