Actinic keratosis (AK) is a skin condition that is caused by long-term sun exposure. It is characterized by scaly, red or brown patches on the skin that may be raised or flat. While AK is not considered to be a serious condition, it can lead to skin cancer if not treated.
The question of whether AK can spread is a common one, and the answer is both yes and no. While AK itself does not spread, the skin damage it causes can. If an AK lesion is not treated, the damaged skin can spread to nearby healthy skin and cause more AK lesions to form. For this reason, it is important to treat AK lesions promptly to prevent them from spreading.
In addition, the skin damage caused by AK can also lead to skin cancer, which can spread to other parts of the body. While AK itself does not spread, it is important to get it checked out and treated as soon as possible to reduce the risk of skin cancer.
In summary, while AK does not spread on its own, the skin damage it causes can spread to nearby healthy skin and potentially lead to skin cancer. It is important to get AK lesions checked out and treated promptly to reduce the risk of skin cancer.
