Several factors seem to influence the development of melanoma:
❑Excessive exposure to sunlight — Melanoma is most common in sunny, warm areas and usually develops on parts of the body that are exposed to the sun.
❑ Skin type — Most persons who develop melanoma have blond or red hair, fair skin, and blue eyes; are prone to sunburn; and are of Celtic or Scandinavian ancestry. Melanoma is rare among Blacks; when it does develop, it usually arises in lightly pigmented areas (the palms, plantar surface of the feet, or mucous membranes).
❑ Hormonal factors — Pregnancy may increase risk and exacerbate growth.
❑ Family history — Melanoma is slightly more common within families.
❑ Past history of melanoma — A person who has had one melanoma is at greater risk of developing a second.
Melanoma is slightly more common in women than in men and is rare in children. Peak incidence occurs between ages 50 and 70, although the incidence in younger age-groups is increasing.
