Actinic Keratosis

An Overview of Actinic Keratosis: Sun-Induced Skin Lesions

Actinic keratosis, also known as solar keratosis, is a condition characterized by the presence of precancerous skin growths. These growths are primarily caused by long-term exposure to the sun's ultraviolet (UV) rays or indoor tanning. Actinic keratosis lesions typically appear as rough, scaly patches on the skin and are considered precursors to skin cancer. While not all actinic keratoses progress to cancer, it is important to monitor and treat them promptly to reduce the risk of developing invasive skin cancer. Regular sun protection measures, such as wearing sunscreen and minimizing sun exposure, can help prevent the development of actinic keratosis.

Actinic Keratosis

Actinic keratosis (AK) is one of the most frequently encountered skin conditions treated by dermatologists. It is estimated that over 40 million Americans develop actinic keratoses (AKs) annually. This prevalence can be attributed to the fact that many individuals do not adequately protect their skin from the sun's harmful effects through the use of sunscreen, protective clothing, and seeking shade.

         When exposed to the sun without protection, the skin is susceptible to damage from the sun's rays. Although the body can repair some of this damage, continual exposure leads to cumulative harm to unprotected skin.

Over time, this accumulated damage can result in precancerous alterations to the skin. Therefore, it is crucial to take preventive measures to shield the skin from the sun's harmful rays and minimize the risk of developing actinic keratosis.

Actinic keratoses (AKs) tend to manifest on areas of the skin that have suffered extensive sun damage. Consequently, they commonly appear on the face, ears, balding scalp, hands, neck, or lips—areas that are frequently exposed to the sun's rays. When an AK develops on the lip, it is referred to as actinic cheilitis. Despite having AKs or actinic cheilitis, individuals often remain in good health and do not experience any associated symptoms or feelings of illness.

Nonetheless, it is crucial to be aware of the presence of these precancerous growths on the skin. Some AKs and actinic cheilitis can progress into a type of skin cancer called squamous cell carcinoma.

Being attentive to changes in your skin can aid in the early detection of precancerous growths. This is particularly important if you have a history of prolonged sun exposure without proper protection or have used tanning beds. It is worth noting that some AKs may appear harmless, resembling age spots, pimples, or irritated patches of skin. On the lips, these precancerous growths may resemble severely chapped lips. Therefore, it is essential to be vigilant and consult a healthcare professional if you notice any suspicious changes or growths on your skin.
