That's why I said "do your research." You don't just randomly take vitamins. Everyone I know who takes lots of vitamins also reads extensively about nutrition and health and has customized regimens to meet his or her personal needs.
As for the before or after question, it's more like "before or during and after." A few took some vitamins before but upped the intake when treatment began, continuing after treatment was successful. Some never took vitamins until treatment began, but they got into vitamins and supplements because even mainstream doctors now recommend some of the well-proven supplements that aid either in fighting the cancer or in fighting the side-effects of cancer. But all included vitamins as part of the treatment, whether or not they took any before hand.
Of my several friends who have had cancer, two in particular are worth noting. One had never taken vitamins before she was diagnosed with stage 4 ovarian cancer. She was given six weeks to live and sent home to die. She went on an extremely rigorous course of vitamins and supplements, even setting her alarm to take supplements at night. Within two months, there was no sign of cancer. She lived another healthy, happy 12 years. Another friend, diagnosed very early with breast cancer and given a very good prognosis chose to do nothing except "cut, burn, and poison" (i.e., surgery, radiation, chemo), not changing her diet and not adding supplements -- even though her doctors begged her to add nutrition and supplements to her treatment. She relied entirely on what was done to her -- including a hellish double bone marrow transplant (as the first person to survive the procedure, she made it into the medical books -- a procedure that has since been discontinued). The cancer went out of control and she died within a few years.
I realize this can be dismissed as anecdotal, but having seen the difference between the two approaches, I'm really clear on which one I'd take.
Of course, they're now finding that the mind is part of the equation, and the person who is determined to get well and is aggressive in taking care of himself or herself has a better chance of recovery than the person who is passive -- or, as was the case of friend two above, is certain that he or she will die. So it is possible that an element of taking vitamins is tied in with deciding to fight illness. But even if mindset does boost the efficacy of vitamins, that certainly wouldn't dissuade me from taking vitamins.
If you don't want to do the homework, then you may be better off not taking too much beyond the usual multi-vitamin. (And even here, some homework is needed. Men and menopausal women should avoid multis that contain iron.) As I mentioned earlier, everyone has different needs -- and different reactions. Just as some people are allergic to aspirin, some are allergic to certain herbs.
From years of reading about this stuff, I'd say the best advice I can offer is don't base any of your vitamin or nutrition decisions on newspaper reports. They get huge amounts wrong, they jump on small and suspect trials if it will make a good headline, they generalize, and they take things out of context. Either read books from reliable sources or get reliable magazines, such as "Prevention." And even then, pay attention to how you react. Because we are all different, there are variations in what works and what doesn't -- which is why most of the reports you see will say stuff like "fifty percent benefitted from taking X."
So either do your homework, or just go to Whole Foods and look for a good, natural, food-based multi for your age and gender.
