I watched a program on vit c giving good results. It was administered by IV. Some people take high dose vitamin c in powder form and there is a product that is a vitamin c also available that can be used orally to emulate vitamin c IV treatment.
I believe turmeric actually destroys cancer cells. Cutting sugar I have read will prohibit cancer cell growth.
In other instances I watched people getting rid of cancer by strict dieting, kbown as a "macrbiotics" diet.
Add to that, cannabis oil. So there are some options out there regardless of if you believe in chemo or not. I personally don't believe in chemo but those who do, the above can be tried in parallel and can't do any more harm.
Most of the information above is gained from watching tv programs that showed people beating cancer. Now I am not saying the above are guaranteed to work, but the way above treatments were shown, the results were surprisingly positive. So if someone is suffering from cancer, they are definitely worth a shot as they can't really bring any harm.
