Reduce Your Risk of Developing Skin Cancer
If you have one or more actinic keratoses (AKs), it’s a sign of skin damage that puts you at a high risk for developing skin cancer. Identifying and treating these precancerous lesions helps you reduce that risk.
Your treatment options depend on how many lesions you have, where they are, your age and overall health. Options include:
Surgery is widely used in cases where a person has one or more isolated lesions. There are several ways to remove the skin lesion with surgery, including:
- Chemical peel: The physician applies a chemical to the face, causing the top skin layers to peel off. New skin generally regrows within a few weeks.
- Cryosurgery: The physician applies liquid nitrogen to freeze the tissue, which eventually falls off, allowing healthy skin to emerge.
- Curettage and desiccation: The physician scrapes or shaves off the lesion, then uses heat or a chemical agent to destroy remaining AK cells and stop any bleeding.
- Laser surgery: The physician applies a laser beam to vaporize the AK lesion.
Topical creams, gels and solutions are prescribed for use in patients with numerous or widespread actinic keratoses. The physician applies these creams and gels directly to affected areas of the skin to treat visible and invisible lesions with minimal risk of scarring.
For widespread AKs located on the face and scalp, a light-sensitizing topical agent is applied for a period of time followed by exposure to blue or red light to kill cancer cells. Photodynamic therapy (PDT) is especially effective as a one and done treatment to destroy lesions without harming healthy tissue.

Doctors may pair therapies for treatment regimens, including
- Cryosurgery and PDT
- Cryosurgery and a topical treatment
- Topical treatments and PDT
Some of these combination therapies can increase photosensitivity. Be sure to check with your dermatologist and be especially careful about safeguarding your skin from UV rays during and after treatment.
