Actinic Keratosis

Often seen as a scaly growth on the face, scalp, ears, shoulders and back of the hands, actinic keratoses (AK) present as scaly lesions that are rough to touch. They can appear as pink, flesh or red lesions, and if not treated, can evolve into squamous cell carcinoma, a type of skin cancer. That’s why AKs are also known as precancerous lesions. At Greenwich Point Dermatology in Greenwich, CT, Dr. Dolder diagnoses and treats AKs in order to prevent cancer development and to remove any unsightly lesions.

What causes actinic keratosis?

AKs form as a result of cumulative exposure to ultraviolet (UV) radiation and appear in areas most readily exposed to the sun. Dr. Dolder encourages the use of sunscreen and sun protective clothing, especially for those with fair skin, blond or red hair, and freckles as they are most sensitive to UV radiation.

What are the treatment options for actinic keratosis?

Luckily, there are a variety of treatment options upon the detection of an AK. Early diagnosis is key in order to not only prevent a cancer from forming, but also to ensure the least invasive treatment options are available.

Treatment options for AK include:

  • liquid nitrogen
  • cryosurgery (freezing)
  • topical treatments
  • photodynamic therapy
  • laser therapy
  • chemical peels
