Actinic keratosis

This is my third and last week of treatment for actinic keratosis using Efudex cream. The healing process will begin next week and will grow new skin tissues in a couple weeks.
AK is a precancerous condition that affects only the top layer of skin (the epidermis). Ultraviolet (UV) rays from the sun damages the skin and if left untreated, 15% of AK can turn into a form of skin cancer called squamous cell carcinoma (SCC). When they are found early, AKs are highly treatable. UV light from the sun and commercial tanning lamps or beds are the major causes of AK. UV light causes changes in the genetic material of the skin's cells. AK can happen at any age, but the risk increases with accumulated sun exposure.
