The most common
warning sign of skin cancer is a change on the skin, especially
a new growth or a sore that doesn't heal. Skin cancers don't all
look the same. For example, the cancer may start as a small, smooth,
shiny, pale, or waxy lump. Or it can appear as a firm red lump.
Sometimes, the lump bleeds or develops a crust. Skin cancer can
also start as a flat, red spot that is rough, dry, or scaly.
Both basal and squamous cell
cancers are found mainly on areas of the skin that are exposed to
the sun -- the head, face, neck, hands, and arms. However, skin
cancer can occur anywhere.
Actinic keratosis, which appears as rough, red or brown scaly patches
on the skin, is known as a precancerous condition because it sometimes
develops into squamous cell cancer. Like skin cancer, it usually
appears on sun-exposed areas but can be found elsewhere.
Changes in the skin are not
sure signs of cancer; however, it is important to see a doctor if
any symptom lasts longer than 2 weeks. Don't wait for the area to
hurt -- skin cancers seldom cause pain.
