Basal cell carcinomas are abnormal lesions or growths in the skin's basal cells which are the outermost and deepest layer. They are usually pink or red and can look like shiny bumps. Basal cell carcinomas usually never spread but should be taken care of early to avoid disfiguring of the site.

Basal cell carcinoma is a skin cancer that frequently develops on parts of the skin that are regularly exposed to the sun, such as the face and neck. Basal cell carcinoma rarely spreads to other parts of the body, although it may move into nearby bone or tissue under the skin.
Basal cell carcinoma is most common in people older than 50 years of age, because it takes many years of sun exposure to develop. People with fair or freckled skin are more susceptible to basal cell carcinoma, and men are more likely to develop it than women.
The condition is caused by long-term exposure to the sun’s ultraviolet rays, which damage the DNA in the basal cells. The damaged cells, which grow and multiply over many years, eventually form a cancerous tumor. Your risk for developing basal cell carcinoma is increased if you were severely sunburned before the age of 18 years.
