Actinic keratosis is a skin condition that sometimes becomes squamous cell carcinoma.
It is a thick, scaly patch of skin that may become cancer. It usually forms on areas exposed to the sun, such as the face, scalp, back of the hands, or chest. It is most common in people with fair skin. Also called senile keratosis and solar keratosis.
Actinic keratosis is not cancer but is treated because it may develop into cancer. Treatment of actinic keratosis may include the following:
- Topical chemotherapy.
- Topical biologic therapy with imiquimod.
- Electrodesiccation and curettage.
- Shave excision.
- Photodynamic therapy.
- Laser surgery.
