A number o f observational studies and clinical trials have shown that physical activity after a diagnosis o f prostate cancer is associated with a decrease in disease progression and an increase in survival, and that specific exercises reduce morbidity from prostate cancer treatments. However, providers need m ore guidance on what types o f physical activity to recommend to patients across different disease states and treatments in prostate cancer, and when and h ow to initiate the discussion.
