What if you don't use AMS? Most suggest that R-up (or is glyphosate cancerous?) won't work at all without AMS....so maybe it's the AMS causing medical problems?

Really though....how does one ever know what caused his/her cancer? I've never heard that Drs say, "oh...looks like glyphosate caused your cancer....or was it bacon?"

I understand respiratory cancers, or other respiratory problems, caused by smoking, but beyond that, how do they know on a personal basis?
