The researchers say they recorded 117 events, including elevations of PSA, secondary treatments, bone metastasis, and prostate cancer-specific death.
"The benefit from walking truly depended on how quickly you walked," Richman says. "Walking at any easy pace did not seem to have any benefit."
Prostate cancer is the second leading cause of cancer death among men. More than 2.2 million men in the U.S. are living with prostate cancer and 217,000 new cases were reported in 2010. Last year, 32,050 men died from prostate cancer.
Stephen M. Schwartz, PhD, senior editor of Cancer Research and a scientist at the Fred Hutchinson Cancer Research Center, says the new study is important because research on the role of physical activity in prostate cancer has been somewhat limited.
"We have had some studies that show a reduced risk of developing prostate cancer, but this is strong evidence of a benefit after someone is diagnosed," he says in a news release.
