Actinic keratosis (AK) is a skin condition that is caused by long-term sun exposure. It is characterized by scaly patches or lesions on the skin, typically on the face, neck, hands, and arms. The lesions can vary in size and shape. If left untreated, AK can develop into a form of skin cancer called squamous cell carcinoma.
Treatment Options
The most common treatment for actinic keratosis is cryotherapy, which involves freezing the lesions with liquid nitrogen. This treatment can be done in a doctor’s office and is usually effective in removing the lesions. Other treatments include topical medications, such as fluorouracil (5-FU) and imiquimod (Aldara). These medications are applied to the skin and can help prevent the lesions from developing into skin cancer.
How Long Can You Leave Actinic Keratosis Untreated?
Actinic keratosis should not be left untreated. If left untreated, AK can develop into squamous cell carcinoma, a form of skin cancer. Therefore, it is important to seek treatment as soon as possible. If you have been diagnosed with AK, your doctor will recommend a treatment plan that is best for you.
