Actinic Keratosis

Some actinic keratoses may temporarily disappear and later return, while others remain stable for years. However, because it is impossible to predict which lesions could progress toward skin cancer, dermatologists typically recommend evaluation and treatment rather than simply waiting to see what happens. Professional monitoring allows suspicious lesions to be addressed before they become more serious.

Actinic keratosis is considered a precancerous condition rather than an actual skin cancer. The abnormal cells are confined to the upper layers of the skin. However, some AKs can eventually develop into squamous cell carcinoma if left untreated. Since the appearance of an AK can sometimes resemble early skin cancer, a dermatologist may recommend treatment or biopsy to confirm the diagnosis and assess the lesion.

People with fair skin, light-colored eyes, a history of frequent sun exposure, or repeated sunburns are at increased risk. Individuals who work outdoors, enjoy outdoor recreation, or have used tanning beds may also develop AKs more frequently. Patients with weakened immune systems often face a higher risk as well. Even if an actinic keratosis has been successfully treated, future lesions can still develop from prior sun damage.

Yes. It is common for patients to develop multiple AKs in areas that have accumulated years of sun exposure. In some cases, clusters of lesions may appear across larger sections of the face, scalp, chest, or hands. When numerous lesions are present, Dr. Michael Krathen may recommend treatment approaches that target both visible and underlying sun-damaged cells within the affected area.

Recovery depends on the treatment method used. Some treatments may cause temporary redness, flaking, crusting, or sensitivity as the damaged skin heals. These reactions are often a normal part of the treatment process. Dr. Krathen will provide specific aftercare instructions and explain what type of healing response is expected. Following these recommendations carefully can help support optimal results and comfort.

The most effective prevention strategy is protecting your skin from ultraviolet radiation. Daily use of broad-spectrum sunscreen, protective clothing, wide-brimmed hats, and seeking shade during peak sunlight hours can significantly reduce additional sun damage. Avoiding tanning beds is also important. Regular skin examinations with a dermatologist allow new lesions to be identified early, when treatment is often simpler and more effective. Because actinic keratoses are a sign of cumulative sun exposure, maintaining consistent sun protection habits can help reduce the likelihood of developing additional lesions and support long-term skin health.
