Q

AK management vs basal cell

A
  • basal cell = wide local excision
  • AK = cryotherapy and surgical procedures, are the primary approach for isolated lesions [3]. Field-directed therapies, such as topical fluorouracil, imiquimod, and PDT, are particularly useful for treating areas with multiple AKs.
