Risk of developing another basal cell carcinoma. A 5-year prospective study

Abstract

This 5-year prospective study of 1000 people, who had one basal cell carcinoma treated, found that 36% develop a second basal cell carcinoma. The most important risk factors are a skin complexion with inability to tan and frequent sun exposure. There was no significant correlation between multiple basal cell carcinomas and sex or age.
