The myriad horrors of the US healthcare system have spawned generations of medical tourism from the wealthiest country on Earth to the periphery: Cuba, Mexico, Costa Rica, Canada, Turkey, and Thailand, to name just a few.

Now, Shanghai is quickly rising as one of the top destinations for cancer patients, as China’s biotech sector has spun an experimental treatment developed in the US into a standalone industry.

New reporting by the Wall Street Journal took a look at this fast-growth industry, centered around chimeric antigen receptor T-cell therapy, or CAR-T for short.

CAR-T is essentially a personalized form of immunotherapy, in which a patient’s own white blood cells are engineered to identify and attack specific proteins found in cancer cells. Though the process was first developed by US biotech giants, their inability — or unwillingness — to lower the cost and increase supply of the treatment has led to shortages throughout the country.

That’s where China comes in. As director of the CAR-T program at the University of Texas MD Anderson Cancer Center in Houston Sairah Ahmed told the WSJ, this therapy can cost around $150,000 to $230,000 in China — still a life-altering bill, but a sizeable discount compared to an insurmountable $550,000 to $850,000 in the US.

This, Ahmed says, is why she advises some patients to seek out treatment in the People’s Republic.

“China has basically done to CAR-T cell therapy the same thing that it’s done to other industries, which is, they’ve industrialized it,” Ahmed explained.

China’s CAR-T services aren’t just cheaper, either. They’re also faster, and come with a host of complimentary after-care treatments, the WSJ notes. As MD Anderson Cancer Center’s explainer on CAR-T therapy advises, the process of extracting and bio-engineering a patient’s cells to fight cancer can take over three weeks in the US. Compare that to China, where the WSJ reports labs near Shanghai can “crank out” the therapy in just a matter of days.

An important caveat here is that CAR-T cell therapy isn’t a catch-all for every type of cancer, and it’s typically only administered after other treatments have failed. It’s not exactly a walk in the park, either, requiring months of recovery and check-ups from a range of physical, neurological, and psychological health specialists. Still, if you had to go through with it, your first step should clearly be pricing out some flights to China.
