From the site:
Ralph W. Moss, PhD, offers phone consultations to his Moss Reports clients to help them individualize their cancer treatment. (Clients are those who have purchased a $297 diagnosis-specific report.) It is important to understand that Ralph Moss is not a medical doctor and the advice he gives is not intended to supplement or replace that given by your physician. Investigating the claims of people who treat cancer is his full-time job.Take your money making schemes elsewhere. F.R. is not an advertising service.
