Exercise Cuts Prostate Cancer Death Risk Jan. 6, 2011 -- Men diagnosed with prostate cancer may be able to reduce their risk of death not just from prostate cancer but from any cause by exercising vigorously for at least three hours per week, new research indicates.

A study performed by researchers at the Harvard School of Public Health and the University of California-San Francisco examined the records of 2,705 men who had been diagnosed with nonmetastatic prostate cancer over an 18-year period in a project known as the Health Professionals Follow-Up Study. The men in the study reported the time they spent exercising on a weekly basis. This included running, bicycling, walking, swimming, other sports, and even outdoor work.
