73 percent increased risk for bladder cancer, 77 percent increased risk for kidney
THURSDAY, June 15, 2017 (HealthDay News) — New research adds to growing evidence that inactivity may be a significant risk factor for cancer, according to a report published online May 19 in Cancer Epidemiology.
Rikki Cannioto, Ph.D., an assistant professor of oncology at the Roswell Park Cancer Institute in Buffalo, N.Y., and colleagues evaluated data for 160 renal cancer patients, 208 bladder cancer patients, and 766 people without cancer.
Cancer risks were similar whether people were obese or not, the researchers said. However, lifetime recreational inactivity was associated with a 73 percent increased risk of bladder cancer and a 77 percent increased risk of renal cancer.
“In this case-control study, we observed evidence of a positive association between renal and bladder cancer with lifetime recreational physical inactivity. These data add to the growing body of evidence suggesting that physical inactivity may be an important independent risk factor for cancer,” the authors write. “Additional studies using a larger sample and prospectively collected data are needed to substantiate the current findings.”
