Study Explores Effects of Exercise on Prostate Cancer Patients

Many studies have supported that physical activity can help to slow down the growth of prostate cancer, and help with some of the side effects of treatment. There is also some evidence that certain foods may slow down the growth of prostate cancer or reduce the risk of it returning after treatment. At the moment, this evidence is limited and we need more research to show clearly how different foods can help.
However, by eating healthily and being physically active you can take more control of your health and do something to improve it. A healthy diet and physical activity can help you stay a healthy weight. They will also benefit your general health and reduce your risk of medical problems such as heart disease, diabetes and other cancers.
Physical activity is tied to improved outcomes for men with prostate cancer, according to results in this particular study presented at AACR. Experts say that men who reported walking at a brisk pace had more regularly shaped blood vessels in their prostate tumors compared with those not having a regular physical activity. The study investigated whether prediagnostic physical activity was associated with prostate tumor blood vessel regularity among 572 men enrolled in the Health Professionals Follow-up Study. They found that men with the fastest walking pace (3.3–4.5 miles per hour) prior to diagnosis had 8 percent more regularly shaped blood vessels compared with men with the slowest walking pace (1.5–2.5 miles per hour).
The findings suggest a possible mechanism by which exercise may improve outcomes in men with prostate cancer. Although data from randomized, controlled trials are needed before we can conclude that exercise causes a change in vessel regularity or clinical outcomes in men with prostate cancer, the study supports the growing evidence of the benefits of exercise, such as brisk walking, for men with prostate cancer.
