Aggressive Exercise Pays Off
It pays to be aggressive. An aggressive walker that is. Researchers found that men who walked at a face pace (3.3 – 4.5 miles per hour) before being diagnosed with prostate cancer had tumors containing larger and more regularly shaped blood vessels. Why is that good? Better formed tumor blood vessels may in turn inhibit cancer aggressiveness and promote better responses to treatments
“Prior research has shown that men with prostate tumors containing more regularly shaped blood vessels have a more favorable prognosis compared with men with prostate tumors containing mostly irregularly shaped blood vessels,“ said lead scientist Erin Van Blarigan, Sc D., of the University of California, San Francisco who presented his finding at the recent American Association for Cancer Research Prostate Cancer Foundation Conference.
“In this study we found that men who reported walking at a brisk pace had more regularly shaped blood vessels in their prostate tumors compared with men who reported walking at a less brisk pace.
Van Blarigan and colleagues used data from 572 men who participated in the Health Professional Follow-Up Study,which was initiated in 1986, enabling researchers to examine how nutritional and lifestyle factors affect the incidence of serious illnesses, such as cancer and heart disease.
“Our 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 exercise causes a change in vessel regularity or clinical outcomes in men with prostate cancer, our study supports growing evidence of the benefits of exercise, such as brisk walking, for men with prostate cancer.”
Future studies will investigate whether increasing brisk walking after a diagnosis is associated with favorable changes in tumor vasculature.
