PSA doubling time, a marker of cancer progression, increased from 28 to 76 months in prostate cancer patients performing exercise training.
“The exercise intervention resulted in marked physiological adaptations that aided weight regulation and increased fitness levels,” Dr. Hojman told Renal & Urology News. “PSA doubling time correlated with improved fitness, but not with weight loss. These findings suggest there is a fitness component that plays a role in the control of prostate cancer that is not related to weight.”

I have been recommending exercise for my prostate cancer patients for many years. I usually recommend 30 minutes of aerobic exercise 3 times a week. In this study, 45 minutes of exercise 3 times a week led to the PSA going up slowly for patients that had regular exercise.
