Actinic keratosis (AK) is a skin condition that is caused by long-term exposure to ultraviolet (UV) radiation from the sun. It is considered to be a precancerous condition, meaning that if left untreated, it may eventually turn into skin cancer. The exact timeline for how long it takes AK to turn to skin cancer is not known, as it can vary significantly from person to person.
However, it is important to note that AKs can develop into skin cancer if left untreated. The majority of AKs, if left untreated, will remain benign. However, some may progress to squamous cell carcinoma (SCC), the second most common type of skin cancer. The progression of AK to SCC can take anywhere from several months to several years, depending on the individual's skin type, level of sun exposure, and other environmental factors.
It is important to note that AKs should be monitored closely by a dermatologist, especially if they are located in sun-exposed areas of the body. If an AK is found to be changing in size, shape, color, or texture, it should be biopsied and treated as soon as possible. Early diagnosis and treatment are key to preventing the progression of AK to skin cancer.
Overall, the timeline for how long it takes AK to turn to skin cancer is not known, as it can vary significantly from person to person. However, it is important to keep in mind that AKs should be monitored closely and treated promptly if any changes occur. Early diagnosis and treatment are key to preventing the progression of AK to skin cancer.
