common in those who have light-colored skin, blue or greeneyes, and blond or red hair –

and overexposure to x-rays or other forms of radiation.

Usually local and almost never spreads to distant parts of the

body, but it may continue to grow and invade nearby tissuesand structures, including the nerves, bones, and brain.

The tumor may be very small in the beginning, growing to 1or 2 centimeters in diameter after several years of growth.









Symptoms

ear, neck, chest, back, or scalp

depending on the size, depth, and location of the

cancer.

Cauterization (burning)

Surgical removal, including microscopically controlled

surgical removal (Mohs' surgery)

Cryosurgery (freezing)

Radiation







Expectations (prognosis) Return to top

Early treatment by a dermatologist may result in a

cure rate of more than 95%.

Complications Return to top

invasion of adjacent tissues or structures, causing

damage to their appearance and function. This is

most worrisome around the nose, eyes, and ears.







Prevention

Protect the skin by wearing protective clothing such as hats,long-sleeved shirts, long skirts, or pants.

Ultraviolet light is most intense at midday, so try to avoid sunexposure during these hours.

Use high-quality sunscreens, preferably with SPF (sun protection factor) ratings of at least 15.

Look for sunscreens that block both UVA and UVB light.

Apply sunscreen at least a half-hour before exposure, andreapply it frequently.

Use sunscreen in winter, too. Examine the skin regularly for development of suspicious

growths or changes in an existing skin lesion. A new growththat ulcerates, bleeds easily or is slow to heal is suspicious
