Actinic keratosis (AK) requires treatment, as it is a precancerous skin condition that can develop into a more serious form of skin cancer if left untreated. AKs are caused by long-term exposure to ultraviolet (UV) radiation from the sun or tanning beds, and typically appear as scaly patches of skin on areas of the body that are most exposed to the sun, such as the face, ears, scalp, neck, hands, and forearms.
Although AKs are not cancerous, they can develop into squamous cell carcinoma (SCC) if left untreated. SCC is a type of skin cancer that can spread to other parts of the body and cause serious health complications. Therefore, it is important to treat AKs to prevent them from progressing to a more serious form of skin cancer.
The most common treatment for AKs is cryotherapy, which involves freezing the affected skin with liquid nitrogen. Other treatments include topical creams, laser therapy, curettage (scraping the skin), and photodynamic therapy (PDT). Depending on the size, location, and number of lesions, your doctor will recommend the best treatment for you.
In conclusion, AKs require treatment as they can develop into a more serious form of skin cancer if left untreated. If you have any AKs, it is important to see a dermatologist to get them treated as soon as possible.
