I've been reading about Graviola in connection with fighting colon cancer.
"It is reputedly "10,000 times stronger in killing colon cancer than Adriamycin, a commonly used chemotherapeutic drug" and has the ability to "hunt down and destroy prostate, lung, breast, colon, and pancreatic cancers ... leaving healthy cells alone!" These are formidable claims. Adriamycin (doxorubicin) is one of the most powerful (and toxic) drugs in chemotherapy. Adriamycin was discovered in Italy in the 1970s, hence the "Adria-tic" name. Now, we are told, an herb has come to light that is not only as powerful as Adriamycin, but 10,000 times more powerful, and non-toxic to boot."
Since I also have colorectal tumors I just ordered some off the net to try. I like the fact that its a natural rainforest herb, and appearently non toxic. It's probably just another tool in the arsenal, but I'll be trying it soon myself. I ordered the Rain Tree brand that I've heard good things about. I bought the powder and empty gel caps for $20 for both that should last for two months. It appearently can also be taken with the Budwigg flaxseed/cottage cheese regimine without any known conflicts.
One other thing that works for me though it's expensive is Goji berries. And only the expensive ones imported from Tibet (not China). But they noticeably make my tumor shrink. When it gets hard to have bowel movements, I'll order more Goji berries and the tumor does definitely receed at least while I'm taking them. The best deal on them is with GojiTrees.com 5 lbs for $60 shipped (and those last me about 3 weeks).
Also diet is everything. No matter what supplements or proceedures she takes, she can defeat them all without the most careful diet. Going the alternative route can work, and give you far more quality of life than the conventional cut, poison, burn and radiate conventional treatment. But it takes supreme dedication and discipline - particulaly with diet to work.
Good luck - your friend's condition sounds absolutely miserable, but she's also very lucky to have you. Probably the best thing you can do for her is to educate her by getting her to curezone, cancertutor and other such sites. The enthusiasm and resolve for beating this has to come from her.
