Thanks for a good question – one that we get often. I'm glad the imagery's been helpful.
I think the best imagery for you to listen to is our Healthy Immune System audio. That will help you visualize healthy cells vanquishing unwelcome ones without invoking an excessive and unnecessary focus on cancer – although a healthy immune system does, in fact, eliminate random, mutant cancer cells all the time, actually. They just never collect enough to pose a threat. Still, no need to use imagery that's entitled "Fight Cancer" when you can have one that says "Healthy Immune System".
As for the excess sugar in your diet, as you already know, it's not the healthiest thing, for cancer avoidance or for a lot of things, and it's good you're using the Weight Loss imagery for that addiction. Very soon Traci Stein will have a new program available called Healthy Weight & Body Image that you may want to try as well.
The funny thing about sugar is the more you eat, the more you crave. Once it's eliminated from your diet, it's pretty amazing how soon your body can stop missing it. So don't give up on that goal!
All best wishes to you,
