More evidence for the protective effect of exercise!

Presented this week at the 10th Annual American Association for Cancer Research Conference (www.aacr.org) was even more data linking physical activity with reduced risk for breast cancer.  


This European trial recruited 520,000 women from 10 European countries and reported on 12 years of follow-up.  The risk reduction was significant for both total physical activity and recreational activity.  When comparing the highest and lowest levels of physical activity, they found that the more activity the fewer tumors! 


The benefit was greatest for Estrogen positive tumors (the most common kind) and the benefit was more robust for postmenopausal women (who have most of the breast cancers).


This, the largest such trial, lead by Dr. Karen Steindorf, from the German Cancer Research Center in Heidelberg, confirms what many other smaller trials have shown: THE MORE ACTIVITY, THE FEWER BREAST CANCERS. 


So have you been on your walk or jog, today?  I enjoyed the 55ยบ weather this morning on a long trek with my dog!  It is not as easy as taking some pill, but it is more fun, has more benefits and has fewer side effects.
