Which treatment is typically used for actinic keratosis?

Liquid nitrogen is commonly used for the treatment of actinic keratosis due to its effectiveness in cryotherapy. This method involves freezing the lesion, which destroys abnormal cells while sparing the surrounding healthy tissue. The application of liquid nitrogen induces a localized inflammatory response that promotes the peeling and eventual elimination of the affected skin after a series of treatments.

Actinic keratosis, characterized by rough, scaly patches on sun-exposed areas, arises from UV light damage. The goal of treatment is to remove these lesions or to reduce their risk of progression to squamous cell carcinoma. Liquid nitrogen therapy is favored for its simplicity, minimal discomfort, and high success rate when used appropriately.

Other treatments listed also have their roles in managing actinic keratosis but may not be the first-line option. Electrosurgery, for example, can be effective but is less commonly used compared to cryotherapy for actinic keratosis. Topical chemotherapy is used for multiple or extensive lesions but may require longer treatment regimens and patient adherence. Surgical excision might be reserved for larger or more suspicious lesions rather than for typical, uncomplicated actinic keratosis.
