My mother was treated for an "AK". What is this and why does it need to be treated? An "AK" or actinic keratosis is a red, scaly area that is usually found on sun- exposed areas such as the face, neck, scalp, and arms. It is considered a pre-cancerous condition because it can develop into a Squamous Cell Carcinoma (a type of skin cancer). There are many treatments for AKs. The simplest and most common is freezing the lesion with liquid nitrogen. See your dermatologist if you have places that you think may be AKs. | |||||||||
