Thanks for the pointers. Lead me to clinicaltrials.gov where 10 studies popped up but none applicable (colon cancer, colorectal cancer, follicualar lymphoma ) plus the completed one you found for "healthy participants with zero history of cancer in 5 years"
Also found a Jan 2009 blog on the same 60 minutes show I saw last night - It was a repeat as it turns out !!! so very old news just recycled. It did have the company name so I can follow up. Thanks
