Linda, you may be filling your body with "FRESH FRUITS AND VEGGIES + 9 VITAMINS", but you're filling your mind with the worst anti-vitamin of all--worry.
I've read (and believe) that as much as 94 percent of our inner dialogue tends to be about the things we fear, our worries, the people we're angry at, our problems, our concerns and so on.
We don't have control over the fact that we have cancer, but we can focus on those things over which we have the most control: our thoughts. If we guide our thoughts and actions in accordance with what we see and hear around us - particularly in the media - we're likely to spend your life in a state of anxiety. That's not good or healthy.
Instead we should really concentrate being positive and optimistic even in the face of difficulties. And the bottom line is that our thoughts are all we really have total control over. Instead of asking and wondering in advance how bad our treatment is going to be, be grateful that there is a treatment, and have an attitude of positive expectancy that it's going to be successful. By asking "WERE THE BCG'S BAD FOR YOU??" you are adding a layer of negativity that doesn't have to be there. Why not ask "what were the BCGs like?" That is the same question without the assumption of it being "bad".
It can't hurt.
