Basal
Cell Carcinoma
What is basal cell carcinoma?
Basal cell cancer, sometimes called non-melanoma
skin cancer, usually appears as a small, fleshy bump or nodule on the head, neck,
or hands. Occasionally, these nodules appear on the trunk of the body, usually as flat
growths. Basal cell carcinoma accounts for more than 90 percent of all skin cancers in the
United States. It is often easily detected and has an excellent record for successful
treatment.
According to the American Academy of Dermatology, the cure rate for basal cell
carcinoma is 95 percent, when properly treated. Although this type of cancer rarely
spreads to other parts of the body, it can extend below the skin to the bone and cause
considerable local damage. And, non-melanoma skin cancer places people at high risk for
developing additional skin cancers.
Who is at risk for basal cell carcinoma?
Basal cell carcinoma is the most common skin cancer found
in Caucasians. It seldom occurs in dark-skinned persons. People who have this cancer
frequently have light hair, eyes, and complexions, and they do not tan easily.
How does basal cell carcinoma develop?
This highly treatable cancer starts in the
basal cell layer of the epidermis (the top layer of skin) and grows very
slowly. A basal cell carcinoma usually appears as a small, shiny bump or
nodule on the skin, and mainly on the areas exposed to the sun, such as the
head, neck, arms, hands, and face.
