Actinic keratosis (AK), also known as solar keratosis, is a precancerous skin condition that affects the areas of the skin that are most frequently exposed to the sun. While actinic keratosis typically does not heal on its own, there are a variety of treatments that can help to reduce or even eliminate the condition.
What Causes Actinic Keratosis?
Actinic keratosis is caused by long-term, excessive exposure to ultraviolet (UV) radiation from the sun or indoor tanning beds. As a result, anyone who spends a significant amount of time in the sun is at risk for developing actinic keratosis. People who are fair-skinned or have a family history of skin cancer are particularly susceptible to AK.
What Are the Symptoms of Actinic Keratosis?
The most common symptom of actinic keratosis is a scaly, rough patch of skin. These patches may be red, tan, pink, or a combination of colors. They may also be itchy, and in some cases, they can bleed.
How Is Actinic Keratosis Treated?
The goal of treatment for actinic keratosis is to reduce or eliminate the precancerous lesions. The treatment options depend on the size and number of patches, as well as the patient's preferences. Options include topical creams, cryotherapy, laser therapy, and surgical excision. In some cases, combination therapy may be used.
Can Actinic Keratosis Be Prevented?
The best way to prevent actinic keratosis is to limit exposure to UV radiation. This means avoiding direct sunlight during peak hours, wearing protective clothing and hats, and using a broad-spectrum sunscreen with an SPF of 30 or higher. In addition, it's important to have regular skin exams to check for any signs of pre-cancerous lesions.
