What is basal cell carcinoma?

A type of skin cancer which begins in the basal cells — a type of cell within the skin that produces new skin cells as old ones die off. It occurs most often on areas of the skin that are exposed to the sun and it may be associated with long-term exposure to ultraviolet (UV) radiation from sunlight.

Symptoms of basal cell carcinoma

  • Black/blue/brown spots or moles, on the skin and lining of the mouth

  • Lumps under the skin

  • Smooth, shiny lump on the skin

  • Sores or ulcers of the skin

Questions your doctor may ask to check for basal cell carcinoma

Your doctor may ask these questions to diagnose basal cell carcinoma

  • Are there black, blue, or brown spots on the skin or elsewhere? (Including moles)

  • Do you feel a lump/lumps under your skin?

  • Is there a shiny or waxy, pearl-like lump on the skin?

  • Do you have skin ulcers (sores)?

Treatment for basal cell carcinoma

Treatments depend on the type, location and size of the cancer. Basal cell carcinoma is most often treated with surgery to remove all of the cancer and some of the healthy tissue around it. Other treatment options include curettage and electrodessication, freezing (cryotherapy), radiation therapy and chemotherapy.
