Risk of Subsequent Basal Cell Carcinoma and Squamous Cell Carcinoma of the Skin Among Patients With Prior Skin Cancer

Abstract

Persons with a prior nonmelanoma skin cancer had a substantial 5-year risk of developing another tumor of the same histologic type. Number of previous skin cancers, solar damage, and skin sensitivity to sun exposure were particularly related to this risk. The increased risk of squamous cell skin cancer associated with cigarette smoking merits further study.
