Yes: Actinic keratoses are pre-cancerous skin lesions caused by sun exposure. Various treatments can be used, including liquid nitrogen (freezing), topical creams (imiquimod, fluoruracil, others), curettage (scraping), and medium-depth chemical peels. Laser treatments include co2 laser ablation and photodynamic therapy (laser treatment after application of a medication to the skin).
