Basal Cell Carcinomas (BCCs)are abnormal, uncontrolled growths or lesions that arise in the skin’s basal cells, which line the deepest layer of the epidermis (the outermost layer of the skin). BCCs often look like open sores, red patches, pink growths, shiny bumps, or scars. Usually caused by a combination of cumulative UV exposure and intense, occasional UV exposure, BCC can be highly disfiguring if allowed to grow, but almost never spreads (metastasizes) beyond the original tumor site. Only in exceedingly rare cases can BCC spread to other parts of the body and become life-threatening. Avoiding the sun and using sunscreen may help protect against basal cell carcinoma.
Basal cell carcinoma is a type of skin cancer
that begins in the basal cells, a type of cell within the skin that produces new skin cells as old ones die off.
Basal cell carcinoma often appears as a waxy bump, though it can take other forms. Basal cell carcinoma occurs most often on areas of the skin that are often exposed to the sun, such as your face and neck.
There are an estimated 2.8 million cases of BCC diagnosed in the US each year. In fact, it is the most frequently occurring form of all cancers. More than one out of every three new cancers are skin cancers, and the vast majority are BCCs. It shouldn’t be taken lightly: this skin cancer can be disfiguring if not treated promptly. Are you at risk? We have the information you need about the prevention, detection, and treatment of basal cell carcinoma.
Frequently, two or more of these features are present in one tumor. In addition, BCC sometimes resembles noncancerous skin conditions such as psoriasis or eczema. Only a trained physician, such as a specialist in diseases of the skin, can decide for sure. If you observe any of the warning signs or some other worrisome change in your skin, consult a physician immediately.
1. An open sorethat bleeds, oozes, or crusts and remains open for a few weeks, only to heal up and then bleed again. A persistent, non–healing sore is a common sign of an early BCC.
2. A reddish patch or irritated area, frequently occurring on the face, chest, shoulders, arms, or legs. Sometimes the patch crusts, and it may also itch. At other times, it persists with no noticeable discomfort.
3. A shiny bump or nodulethat is pearly or translucent and is often pink, red, or white. The bump can also be tan, black, or brown, especially in dark-haired people, and can be confused with a mole.
4. A pink growthwith a slightly elevated rolled border and a crusted indentation in the center. As the growth slowly enlarges, tiny blood vessels may develop on the surface.
5. A scar-like areathat is white, yellow or waxy, and often has poorly defined borders; the skin itself appears shiny and taut. This warning sign may indicate the presence of an invasive BCC that is larger than it appears to be on the surface.
Factors that increase your risk of basal cell carcinoma include: Chronic sun exposure or exposure to arsenic; exposure to radiation, (Psoralen plus ultraviolet A (PUVA) treatments for psoriasis may increase your risk of basal cell carcinoma and other forms of skin cancer. Having undergone radiation treatments for childhood acne or other conditions also may increase your risk of basal cell carcinoma); fair skin (particularly if you freckle easily); biological gender and age, menare more likely to develop basal cell carcinoma than women are. As basal cell carcinomas often take decades to develop, the majority of basal cell carcinomas occur in people age 50 or older. If you are taking immune suppressing drugs, especially after transplant surgery, this will significantly increase the risk of skin cancer as does a familial history of skin cancer.
