I too have discussed this science with an oncology expert. What's to prevent a "witch hunt" from occuring when a serum positive result is obtained via uptake from an antibody and the afp receptor? This is one issue I meant to discuss with Dr Moro recently--can the blood test determine from what source(cancerous) the sloughed off cells come from? From prostate, breast, etc., or do you then need a tissue sample from a source that needs to be independently verified? Thus, the issue of multiple, hysterical tests and invasive diagnostic procedures.....the recent prostate commentary from the company sounded like a positive statement on the serum test alone being able to differentiate the likely tumor source, which made my contact/dear friend, professor emeritus and all, surmise that, if true, the biocurex blood test along with a psa would be a compelling union of two simple tests...food for thought-perhaps someone on the board can enlighten all on the ability of the serum test to identify cell type.....scouty
