Actinic keratosis (AK) is a precancerous skin condition that develops after years of exposure to UV rays from the sun. It is estimated that more than 58 million people in the United States have AK, and it is most common among fair-skinned people and those who spend a lot of time in the sun.
The length of time that a person can have actinic keratosis depends on a variety of factors, including the severity of the condition and the person’s skin type and lifestyle. Generally, the longer a person is exposed to UV rays, the more likely they are to develop AK. People who are more prone to sunburn and those with lighter skin types are most at risk.
AK is a chronic condition that can last for years, and in some cases, may never go away. If left untreated, AK can lead to more serious skin conditions, such as squamous cell carcinoma (SCC). It is important to seek medical attention if you have any signs or symptoms of AK, such as a scaly patch of skin that does not heal. A doctor can diagnose AK and recommend a treatment plan that is right for you.
In many cases, topical medications are used to treat AK. These medications are usually applied directly to the affected area and can help to reduce the symptoms. In more severe cases, cryotherapy or laser treatments may be recommended. These treatments can help to reduce the size of the lesions and, in some cases, can completely remove the AK.
No matter how long you have actinic keratosis, it is important to take steps to protect your skin from the sun. Wear a broad-spectrum sunscreen with an SPF of at least 30 and try to limit your exposure to the sun during peak hours. You should also cover up with long sleeves and a wide-brimmed hat when outside. These preventive measures can help to reduce your risk of developing AK and other skin conditions.
