What is keratoses?

• Although actinic keratosis is not a skin cancer, it is considered to be precancerous • If these lesions are not treated, they can develop into squamous cell carcinomas • People with actinic keratosis are more likely to develop other types of skin cancer such as basal cell carcinoma and melanoma • So we have to treat all actinic keratoses, since it is impossible to know which ones will turn into skin cancer
