- Childhood sunburns , freckling, or long periods of sun exposure
- Fair skin that rarely tans
- A family history of skin cancer

- A shiny bump that can be pearl-like in appearance or, less often, dark in color, much like a mole
- A pink growth with a slightly raised border and dip in the middle
- A patch of skin that seems shiny and tight, much like a scar
Diagnosis
Treatment
- Mohs micrographic surgery—microscopic surgery that offers the best cure rate for basal cell carcinoma
- Removal of the growth with simple surgery
- Plastic surgery to repair any cosmetic problems that occur after treatment
- Electrodesiccation and curettage—treatment to remove section of skin
- Use of liquid nitrogen to freeze the growth
- Radiation therapy
- Photodynamic therapy—the cells absorb an acid that causes them to die when exposed to light
- Creams, especially fluorouracil or imiquimod
Prevention
- Reduce your sun exposure. Wear sunscreen, long sleeves, pants, and hats.
- Stay out of the sun during the middle of the day.
- UV light is stronger at higher elevations. If you ski or do other winter sports, wear sunscreen.
- At-risk adults should examine themselves monthly. They should also get regular full-body exams by a dermatologist. The doctor will check for moles, freckles, and other growths.
- Limit how much time your child spends in the sun. Discourage your child from tanning.
