Body weight and colorectal cancer risk in a cohort of Swedish women: Relation varies by age and cancer site

Abstract

The relation between relative body weight and colorectal cancer among women is unclear. In a large prospective cohort study, we found a positive association only for distal cancers among younger women that became attenuated at older ages. These results support previous reports in which results were stratified by age or colorectal cancer site. © 2001 Cancer Research Campaign.
