Basal Cell Carcinoma
Although basal cell carcinomas are the most common type of skin cancer, they grow slowly, usually on sun-exposed skin in the head and neck areas, but they can occur anywhere on the body.
Basal cell carcinomas look like a variety of other marks on the skin. They often appear as flat, firm, pale areas or small, raised, pink or red, translucent, shiny, pearly areas, which bleed after a minor injury.
This type of skin cancer may also have a lower area in its center, one or more abnormal blood vessels, and areas that are blue, brown or black. Crusted or oozing areas may appear in larger basal cell carcinomas.
Warning signs include a spot or bump that’s getting larger over time, new growths, or a sore that doesn’t heal within a couple of months.
While it is rare for a basal cell cancer to spread (or metastasize) to other parts of the body, if left untreated it can spread into the bones or other tissues under the skin.
Once treated, basal cell cancers can recur, often in the same place on the skin. As many as 50 percent of people who have been diagnosed with one basal cell cancer will develop a new skin cancer within five years.
