Actinic keratosis (AK) is a skin condition caused by sun exposure that can lead to skin cancer. It is characterized by thick, scaly patches that are often red, brown, or gray in color. While AK can range in size from very small patches to large plaques, the overall size of the patches does not generally increase over time.
However, the number of patches can increase with continued sun exposure. AK lesions can also become thicker or darker over time. This is why it is important to take steps to protect your skin from the sun and to get regular skin checks from your doctor.
The patches of AK can be removed through a variety of treatments, such as cryotherapy, topical medications, or laser treatments. These treatments can help prevent the AK from becoming cancerous. However, if the AK is not treated, it may become cancerous.
Overall, actinic keratosis does not generally grow in size. However, the number of patches and their thickness can increase over time. Therefore, it is important to take steps to protect your skin from sun exposure and to get regular skin checks.
