Unless you're eating foods that contain carcinogens (things that cause an increased occurrence of random genetic mutations), there's nothing in your diet that has been proven to increase your risk of cancer.
Once you have cancer eating more foods with a high glycemic index will help feed the tumors and the resulting insulin from eating those foods will stimulate them to grow faster.
Exercise increases muscle mass and burns glucose and therefor helps to use up that sugar and reduce your body's need to produce insulin and therefor it helps to slow down the growth of the tumors, but it will not stop them and it will not make them go away.
Cancer is caused by specific random genetic mutations in combination with your immune systems failure to detect and destroy the mutated cells. This is something that can and does happen in the most healthy of us as well as the most unhealthy of us.
By the way, a lot of fruit have a high glycemic index and those fruits should be avoided.
Another thing, chemo is way more toxic and bad for you than any processed foods or nitrates, and without it your cancer will not go away. You never know, processed foods and nitrates might be just as bad for your tumor cells as it is for you, or it might be even worse for your tumor cells just like chemo.
Unless there are peer reviewed studies, you can assume as much as you want but don't believe any of it. When someone tells you something, look it up and read it about it and look for peer reviewed studies before believing anything.
Here are a coupe of articles you might want to take a look at.

A high protein moderate carbohydrate diet fed at discrete meals reduces early progression of N-methyl-N-nitrosourea-induced breast tumorigenesis in rats

Although tumor latency was not different between groups, once palpable tumors began to appear, the rate of tumor appearance proceeded more rapidly in the LPHC group. This suggests that either reduced dietary carbohydrate or elevated dietary protein (or both), can attenuate the early development of mammary tumors. In agreement with our previous study [17], post-prandial insulin at 3 wk was elevated in the LPHC group and not in the HPMC group. Thus, animals in the LPHC group were likely exposed to higher, repeated elevations in serum insulin following each discrete meal during the period leading to the emergence of palpable mammary tumors. |
If I'm understanding that quote correctly it means that a low carb diet didn't stop the cancer from developing, but it did slow the growth and development of new tumors.
Cheri, I believe you're doing the best possible thing to help slow down your progression and improve the efficacy of your treatments. Keep it up as much as you can.
