Briskly Walking Away from Prostate Cancer?

Stockbyte/Thinkstock(BOSTON) -- There hasn't been much research on whether physical activity is important for people with prostate cancer.  But now a study from the Harvard School of Public Health of nearly 1,500 patients diagnosed with prostate cancer that had not spread, suggests that brisk walking could "delay or even prevent progression" of prostate cancer.

The study's key finding was that men who walked briskly for three hours a week reduced their risk of the cancer progressing compared to men who walked at an easy pace less than three hours a week.  

This study adds to earlier research by this group which found vigorous physical activity following diagnosis was link with reduced risk of prostate cancer death.

Critics of the report may find its accuracy to be questionable.  The authors relied on questionnaires filled out by the patients one year after diagnosis, which begs the question: Do they really remember accurately how "briskly" they walked and for what duration such a long time ago?

These findings are published in the journal Cancer Research.
