What you do after diagnosis matters more than before

Here's one of the most important things I learned at the Be Active conference in Sydney: the amount of exercise you do after cancer diagnosis has a much greater impact on your survival than what you did before diagnosis. If you were sedentary, and become active, your chances of survival are just as good, or perhaps even better, than someone who was active the whole time. There is some preliminary evidence that those who were moderately active both before and after diagnosis (but had no increase in physical activity levels) were worse than those who were sedentary and became active.

So, simple thing is: after cancer, exercise more than you did before diagnosis, no matter how active you thought you were. And if you're like me, and already do almost 3 hours a day, well, I guess you're jumping up to 4 hours a day.
