Actinic Keratosis is a precancerous lesion, of the outer layer of skin that is caused by long term exposure to sunlight. Sunlight exposure alters the skin cells and causes areas of the skin to become scaly, rough, discolored and sometimes tender to the touch. Actinic Keratosis is usually found on the face, lips, ears, neck, scalp, forearms and backs of hands. People with fair skin and light colored hair and eyes are at greatest risk of developing Actinic Keratosis.
Actinic Keratosis is non-life threatening if it is diagnosed and treated in the early stages. If left untreated it can develop into squamous cell carcinoma.
Once the dermatologist has determined you have an Actinic Keratosis lesion she will discuss treatment options. Options include cryosurgery, topical chemotherapy creams, photodynamic therapy, chemical peels and laser resurfacing therapy.
