Risk Factors of Melanoma



While the causes of melanoma may range from genetic influences (including family history) to environmental reasons (overexposure to ultraviolet radiation through sunlight), certain risk factors make some individuals more prone to melanoma than others. Melanoma risk factors include:

  • Skin Color: Individuals with lighter complexion, natural red or blonde hair and light colored eyes maybe at a higher risk of contracting melanoma. This is because these individuals possess less amount of the natural pigment in the skin, 'melanin' which protects against harmful UV rays of the sun. Sunburns or freckles due to sun exposure are more common amidst individuals with light complexion increasing their risks of melanoma.
  • Overexposure to sun and conditions such as sunburns and blisters in childhood or youth may increase the chances of contracting melanoma later in life. Individuals who are addicted to tanning beds and lamp may also face elevated risk of melanoma.
  • Geographically, some individuals face a higher risk of melanoma than others do. People living close to the earth's equator face more direct sunlight and may face the risk of melanoma due to high amounts of UV radiation. Similarly, sun exposure in high altitudes may result in melanoma.
  • If you notice skin growths such as moles and warts in unusually high numbers on your body, you maybe at a risk of suffering from melanoma. While not all moles are dangerous, it is necessary to seek medical help if existing moles change size or appearance, spread to nearby areas or new ones crop up increasingly.
  • A family history of skin cancers or other types of cancer may put you in a risk bracket for contracting melanoma. Individuals with weak immune systems may also face a risk of melanoma. The weak immune system may result from prolonged illness, organ transplant, medication and infections that lower immunity.
