Complications
By Mayo Clinic staffComplications of basal cell carcinoma can include:
- A risk of recurrence. Basal cell carcinomas commonly recur. Even after successful treatment, they may recur, often in the same place.
- An increased risk of other types of skin cancer. A history of basal cell carcinoma may also increase the chance of developing other types of skin cancer, such as squamous cell carcinoma and melanoma.
- Cancer that spreads beyond the skin. Rare, aggressive forms of basal cell carcinoma can invade and destroy nearby muscles, nerves and bone. Very rarely, basal cell carcinoma can spread to other areas of the body.
