Causes of Melanoma Skin Cancer

Skin cancer is the most common type of cancer, accounting for as many as half of all cancer cases diagnosed each year. Melanoma skin cancer is particularly dangerous because it can spread rapidly. Nearly 79 percent of all skin cancer deaths are due to melanoma. If you have noticeable spots or freckles that begin to change in appearance (become darker or larger), see a dermatologist.
  1. Ultraviolet Rays

    • Too much sun exposure--along with tanning booths or beds--is a danger to the skin. Severe sunburn can also increase the risk of melanoma.

    Family History

    • About 10 percent of melanoma patients have a family history of the disease. People who have an immediate relative (parent, sibling, child) with melanoma are considered to be at high risk of developing it themselves.

    Immunity

    • People who take medications that suppress the immunity system have a higher probability of developing melanoma.

    Gender

    • Men have a higher risk of skin cancer than do women.

    Radiation and Injury

    • Exposure to radiation can cause skin cancer in the area that was exposed. People who have burns, severe scars or other skin diseases can also develop cancer.

    Psoriasis Treatments

    • People who have undergone psoriasis treatments such as psoralen increase their risk of skin cancer.
