Of every procedure in the medical tourism playbook, stem cell therapy for Canadians is the one where the marketing has travelled furthest ahead of the science. Dental implants in Los Algodones do exactly what the brochure says. A hip resurfacing in India is the same operation you’d get in Toronto, three years sooner. But when a clinic in Panama or Colombia tells you that an intravenous drip of umbilical cord cells will reverse your MS, rebuild your knees, calm your child’s autism, and knock a decade off your biological age — all from the same bag — you are no longer looking at a healthcare transaction. You are looking at a sales funnel.
