Cancer-specific Studies in the NCI Division of Cancer Epidemiology and Genetics
Physical Activity, Body Mass Index, and Ovarian Cancer
The NIH-AARP Diet and Health Study prospectively investigated the relations of self-reported moderate and vigorous physical activity and body mass index (BMI) to ovarian cancer. Neither moderate nor vigorous physical activity showed a statistically significant association with ovarian cancer in this large cohort of women. Researchers suspect that obesity is associated with enhanced ovarian cancer risk through a hormonal mechanism.
