Why have it done in China specifically?

China offers this advanced treatment at a significantly lower cost—approximately $9,500 compared to $30,000–$50,000 in the U.S. or Western Europe—without compromising on technology. Chinese cancer centers are equipped with state-of-the-art linear accelerators and HDR afterloading systems, and many oncologists have high patient volumes, translating to extensive procedural experience. Additionally, streamlined outpatient protocols reduce hospital stays, while international patient departments provide language support and logistics assistance.
