I guess many know how much I talk about OPC's and as I said the reason I started on them in 1995, we were told "May" prevent cancer(s).
I've been watching a thread of many doing the colonoscopies and I have never done one nor do I plan to. I'm sure my mind is engrained in the "may" prevent cancer comment on the OPC's. I've lived with that comment for over two decades.
Many cancer research centers are using OPC's in their research...city of hope, mayo, univ of maryland....and others.
Here is a link I don't think I read before last night.
