Researchers are still working to determine exactly what causes melanoma, but studies have identified numerous risk factors that can increase a person’s chances of developing this malignancy. As such, melanoma prevention generally centers on avoiding these risk factors.

Some melanoma risk factors can’t be controlled, such as being at an advanced age or having light-colored hair and eyes, fair skin or a family history of the malignancy. Others, however, can be avoided by making certain lifestyle changes. One of the most significant controllable melanoma risk factors is excess exposure to sunlight and other ultraviolet (UV) radiation, so if you want to lower your chances of developing melanoma, you should:

  • Use sunscreen (many experts recommend using a broad-spectrum sunscreen with an SPF of 30 or higher that protects against both UVA and UVB rays)
  • Wear protective attire when outdoors (for example, a hat, sunglasses and UPF clothing)
  • Stay in the shade whenever possible
  • Avoid going outside in the middle of the day, when the sun is highest in the sky
  • Avoid using sun lamps and tanning beds

In addition to reducing your UV exposure, you should take steps to keep your immune system as healthy as possible. Also be sure to regularly check your skin for new or abnormal moles so that you can show them to a physician and undergo treatment (if necessary) before they develop into melanoma.

  • Beta carotene (found in apricots, cantaloupe, carrots, mangoes, squash and sweet potatoes)
  • Lycopene (found in apricots, blood oranges, guava, papaya, pink grapefruit, tomatoes and watermelon)
  • Omega-3 fatty acids (found in albacore tuna, flaxseed, herring, mackerel, salmon, sardines and walnuts)
