Long term exposure to the sun may cause an actinic keratosis (AK). They can appear as a small rough, scaly spot or patch most commonly found on the top of the head, face, back of the neck, hands and lower arms and chest. Fair-skinned people who have been sun-exposure for years are more prone to developing actinic keratosis. An actinic keratosis can develop into cancer and should be treated right away.
If you think you have some Actinic Keratoses, they can easily be treated when discovered early. Your physician can assess your skin for AKs.
