I agree that a survey administered here, and not deisgned by someone with expertise in research in this area, is likely to produce more harm than good.

We'd all like to have the magic key to preventing recurrence, and taking better care of one's overall health and diet certainly can't hurt (and makes you feel like you're doing something), but one has to be careful drawing strong conclusions even from the the diet studies, because it is actually very hard to control people's diets so they are usually only correlational in nature (meaning you can't draw firm conclusions about causlity). And there is even conlficting data about whether antioxidants are helpful or harmful.

I'd hate to see someone drawing erroneous conclusions from some kind of survey done here.
