primary cause of melanoma

Melanoma is the most dangerous form of skin cancer. It begins in the pigment cells of the skin, which produce the dark brown pigment known as melanin. Melanoma develops when these pigment cells become cancerous and begin to grow and spread. Dermatologists believe that the primary cause of melanoma is ultraviolet (UV) radiation from the sun and artificial sources. Exposure to UV radiation is the biggest risk factor for melanoma. UV radiation from the sun is particularly dangerous, as the damaging rays of UV radiation are able to penetrate through skin and cause damage to cells even on the cloudiest and coolest days. Spending even small amounts of time in the sun, such as for 10 minutes on a sunny day, can increase your risk of developing melanoma significantly. Even indoor tanning beds and sun lamps, which produce artificial UV radiation, pose a risk for melanoma. Other risk factors for melanoma include a family history of skin cancer, the presence of moles on the skin, having light-colored skin, and living in areas near the equator. Additionally, individuals with weakened or impaired immune systems are at an increased risk for melanoma. The key to preventing melanoma is protecting yourself from ultraviolet radiation. To reduce your risk of melanoma, dermatologists recommend limiting your exposure to the sun, using sunscreen with an SPF of 30 or higher, wearing wide-brimmed hats, long-sleeved shirts and long pants, and avoiding indoor tanning beds. By taking proper precautions, individuals can reduce their risk of developing melanoma and other forms of skin cancer. Regular visits to a dermatologist can also help to detect any suspicious changes to the skin that may suggest melanoma. If detected early, melanoma is often highly treatable.
