Cancer-specific Studies in the NCI Division of Cancer Epidemiology and Genetics
Body Mass Index, Physical Activity, and Bladder Cancer
The NIH-AARP Diet and Health Study investigated the associations between body mass index (BMI) and other components of energy balance to bladder cancer in nearly 500,000 U.S. men and women, followed from 1995 to 2003. Compared with normal weight in the study, obesity was associated with up to a 28% increased risk for bladder cancer. Physical activity showed no statistically significant relation with bladder cancer.
