skin cancer

Actinic keratoses are small, pink-red, tender, scaly, flaking spots of skin. Individual ones are usually found on areas of prior sunburns from childhood on the face, scalp, chest, back, or shoulders. They need to be evaluated for in-office liquid nitrogen treatment, also called cryotherapy. Extensive sun damage, multiple actinic keratoses, may benefit from prescription chemotherapy cream for home use.
