I can't understand how squirting coffee up your butt does anything. Why not drink it? Gerson also wants you to stand around all day making juice out of pounds and pounds of organic fruit and veg. Why not just eat the stuff at meal time? It makes no sense but desperate people will do desperate things. And get their life-savings drained, then dying anyway.
Problem is there is no one cancer. There are many cancers that require different treatments. They've made a lot of headway for cancers like childhood leukemia and breast cancer but for many cancers there's still way more research needed. And some cancers are just plain incurable, for now. Yes, chemo and radiation are awful and oftentimes don't work wonders but paying scamsters tens of thousands for unproven "treatments" where most everybody dies, makes no sense at all. The ones who survive, if you dig deep enough, have had surgery and chemo/radiation, but they tout the "alternative" treatment as being the reason for their success. Because it gives them a sense of empowerment, like they cured themselves versus helplessly depending on the cold hand of the medical establishment.
People are free to choose whatever they want for their medical treatment. Me, I'll go with the regular medical world. They don't promise 100% because they realistically, truthfully can't make that promise. Cancer sucks that way. The scamsters will promise wonders and guaranteed cures, which for me is a warning sign. Then if it doesn't work and you die, they blame you for not following their protocols 1000%, or for stuffing up something along the way, or maybe not believing enough. It's never them, it's all your fault. Another warning sign.
