US Mexico Cancer Institute

At the US Mexico Cancer Institute in Tijuana, we don’t make bold claims—we track real outcomes. Led by Dr. Héctor Adrián Duque Martínez, a PhD in Molecular Biomedicine and one of Mexico’s leading experts in NK cell therapy, our lab has prepared over 4,000 NK cell doses since 2019. Our method relies on precision, integrity, and the body’s own immune blueprint. We use Natural Killer (NK) cells the way they’re meant to work: fresh, potent, and donor-derived. Expanded over five days to 300 million cells. Delivered intravenously. Never frozen, never reused, never speculative—and never marketed as a one-size-fits-all cure. In the right cases, we’ve seen clear improvements: restored energy, stronger immunity, even remission. Results often begin to show within 21 days. When the immune system still has something to respond with, our job is to help it remember how.
