Rick Hill was diagnosed with aggressive Stage 3 terminal cancer by the Mayo Clinic. The doctors reportedly informed him he had only days left to live.

Instead of accepting this prognosis, Hill traveled to Tijuana for a treatment regimen that led to his complete remission within 21 days. As of today, 50 years later, Hill remains cancer-free.

The case is among hundreds documented by the Richardson Nutritional Center (RNC) over decades.
