Actinic keratosis (AK) is a common skin condition that is caused by long-term exposure to ultraviolet (UV) radiation from the sun. It is marked by the appearance of scaly, rough patches on sun-exposed areas of the skin. These patches are usually red, pink, or skin-colored and typically measure between 1-10 millimeters in diameter. While AK is not cancerous, it can develop into squamous cell carcinoma, a type of skin cancer, if left untreated.
Progression of Actinic Keratosis
Actinic keratosis is considered a precancerous skin condition, and it is important to recognize its early signs and seek treatment as soon as possible. The rate of progression of AK varies depending on the individual, and can range from slow to rapid.
Most people with AK will only experience mild symptoms initially, such as dry, scaly patches of skin. Over time, these patches can become thicker and raised, and may take on a red, pink, or skin-colored hue. In some cases, the patches can become painful or itchy.
In more severe cases, AK can progress to squamous cell carcinoma, a type of skin cancer, if left untreated. This is more likely to occur in people who have a weakened immune system or have had multiple AK lesions for a long period of time. In addition, people who do not practice adequate sun protection are more likely to experience rapid progression of AK.
Treatment of Actinic Keratosis
The best way to prevent AK from progressing is to seek treatment as soon as possible. Treatment options for AK include cryotherapy, topical medications, and laser therapy. It is important to discuss with your healthcare provider which treatment option is best for you.
In addition to seeking treatment, it is important to practice sun protection to prevent further damage to the skin. Wearing protective clothing and applying sunscreen with SPF 30 or higher can help protect the skin from UV radiation and reduce the risk of AK progressing to skin cancer.
By recognizing the early signs of actinic keratosis and taking steps to protect the skin from UV radiation, you can help reduce the risk of AK progressing to skin cancer.
