Actinic keratosis (AK) is a precancerous skin condition caused by sun damage. It is characterized by scaly, reddish patches of skin that can become thick and crusty over time. Although AK is not cancerous in itself, it can develop into a form of skin cancer called squamous cell carcinoma (SCC) if left untreated.
There is no definitive answer to the question of how long it takes for AK to turn to cancer, as it depends on a variety of factors, including the individual's age, skin type, and lifestyle. Generally speaking, the longer AK is present, the more likely it is to become cancerous. However, the progression from AK to SCC can occur in less than a year for some people, or it may take many years for others.
It is important to note that while AK can eventually become cancerous, the risk of this occurring is relatively low. However, if left untreated, AK can become more serious and potentially spread to other parts of the body. Therefore, it is important to have regular skin checks with a dermatologist and take preventive measures, such as avoiding sun exposure and wearing protective clothing and sunscreen. Early detection and treatment of AK can help reduce the chances of it developing into cancer.
