Diet plus exercise up survival after breast cancer

I have great success in finding information on the internet by using Google NEWS alerts. I tend to avoid blogs and websites. Am looking for news articles which will inform me.  The benefit of this (also) is that I see if news comes from many, multiple different places. It is redundant to me, but also highlights the importance of the information.

One of the bits of news that I've seen over and over recently is the following article about diet and exercise.

For me, old habits die hard... I think every day about walking, but use my current chemo as an excuse (too tired; will do it after chemo). And, fruits and veggies have never been a staple for me. Still, I'm determined to do what I can, and see every small bit of improvement as a step in the right direction.
