Actinic keratosis (AK) is a skin condition that is characterized by the development of precancerous lesions or scaly patches on the skin, typically in areas that have been exposed to the sun. Treatment of AK can be effective in removing the lesions and reducing the risk of them progressing to a more serious type of skin cancer known as squamous cell carcinoma.
However, it is important to note that there is a risk of AK returning after treatment. This is because the underlying cause of AK is sun damage, and if a person is not taking steps to protect their skin from further sun damage, the lesions may recur. It is also possible for new lesions to develop in areas that have not been previously affected.
In order to reduce the risk of AK recurring after treatment, it is recommended that a person takes steps to protect their skin from further sun damage. This includes using a broad-spectrum sunscreen with an SPF of 30 or higher when outdoors, avoiding direct sun exposure during peak hours, wearing protective clothing such as a hat, sunglasses, and long sleeves, and avoiding tanning beds.
It is also recommended that a person has regular skin checks with their dermatologist to monitor for any new or recurring lesions. This is especially important for those who are at a higher risk of developing AK, such as those with fair skin, those with a history of skin cancer, and those who spend a lot of time outdoors. Early detection of AK is important for successful treatment, and regular skin checks can help to ensure that any new or recurring lesions are detected early and treated promptly.
