To the Editor: In their study of the incidence of basal cell and squamous cell carcinoma in persons younger than 40 years, Dr Christenson and colleagues1 attribute the increased incidence of nonmelanoma skin cancer to increased UV exposure and decreased ozone protection. They discount a role of increased surveillance because the maximum and median tumor size did not decrease over time.
