People who have had cancer and survived are often inspired to get into better shape with nutrition and exercise to fend off any further cancer or to be in fighting shape should it happen to recur. Cancer cells can't live in oxygenated blood....a great motivator for exercise. Also, women with estrogen related cancers are 80% more likely to NOT have a recurrence if they lose weight (another reason to eat better and exercise). Having had both uterine and ovarian cancer, I can tell you that the above reasons are a HUGE motivator for me to get into better shape. My hips still haven't recovered 100% from chemo nor has my energy level but I'm doing my best and I'm going to do my best to get through the 10K which may not be much for some, but it's BIG to me!!!! Anyway, I hope that you might consider donating even a few bucks. The LIVESTRONG organization does so much for so many...everything from support for patients and families to research to to nutrition/exercise to community awareness and advocacy.
