Treatment: Actinic Keratosis
Precancerous Lesions

There are several treatments your health care professional may use for your actinic keratosis. Choice of treatment depends on the extent and location of the precancerous lesions.

 
Medical

Topical chemotherapy
  • Uses chemotherapy agents, like 5-fluorouracil (Efudex, Carac), to treat precancerous cells.
Topical immunomodulators
  • Imiquimod (Aldara) is a recently FDA (Food and Drug Administration) approved topical cream that may stimulate an immune response against precancerous cells.
Topical anti-inflammatory agents
  • Diclofenac (Solaraze) is another recently FDA approved topical gel that may eliminate some actinic keratoses over a 90-day treatment period.

Surgical

Cryotherapy

  • Precancerous lesions are frozen and destroyed with liquid nitrogen.
Curettage and Electrodesiccation
  • Precancerous lesions are scraped away with a curette, a semi-sharp, scoop-shaped instrument. The area is then cauterized with an electric needle to control bleeding and treat any remaining precancerous cells.

Laser

Photodynamic therapy (PDT)

  • A laser is used to remove or destroy precancer cells.
