one knows what causes this most serious form of skin cancer, but there is evidence that points to prolonged exposure to sunlight as a main culprit in the increased number of cases reported in recent years.
Melanoma normally begins as a harmless mole on the face, arms
or trunk. People
with fairer skin, or who have a family history of melanoma, are more likely to
develop the disease. In people 59 years of age or older, mole-like growths may also eventually result in scalp or neck melanomas.
most common melanoma is referred to as superficial spreading melanoma which, as the name suggests, usually forms on the skin's uppermost layer before it becomes invasive. A typical sign is when a mole begins to change shape, darken, or otherwise change
The most common technique for detecting superficial spreading melanoma is the acronym ABCDE:
• Asymmetrical skin lesion • Border of area is irregular • Color varies from brown, to tan or pink (with cracking, bleeding, and/or itching) • Diameter of mole is greater than 6mm • Evolution of mole, a sign of malignancy
Similar to the superficial spreading type is lentigo melanoma, which develops slowly and
begins as a flat or slightly elevated tan or dark brown growth most commonly seen in the elderly who have severely sun damaged skin.
slow to spread, acral lentiginous melanoma is the most common seen in African-Americans and Asians, and usually appears as a black or brown discoloration under the nails, on the palms of the hands, or the soles of the feet.
Melanoma prevention and treatment
Nodular melanoma is a rare though fast-growing form of the disease
Early detection is important because if allowed to develop, the cancer becomes more difficult to treat, and may even begin to spread to other parts of the body and can be fatal. If recognized and treated in its early stages, there is a successful outcome in almost all cases following a simple outpatient surgical procedure that
excises or cuts away the melanoma from the skin surface.
Early treatment and detection for nodular melanoma - a rarer form of the disease which is more aggressive and faster growing - is of the utmost importance since it is usually becomes invasive from its earliest stages.
To decrease the risk of developing skin cancer in all of its forms, most experts suggest limiting exposure to the sun by wearing clothing that protects the arms, legs and head from damaging UV rays. The use of sunscreen with a maximum SPF of 30 and avoidance of tanning salons is also highly recommended. If there is suspicion that a mole or blemish has recently changed shape or color, consult with your doctor as soon as possible.
