Why have it done in China specifically?

China offers Gamma Knife treatment at approximately $9,500, which is 40–60% less than comparable care in the U.S. or Europe, while using the same latest-generation Leksell Gamma Knife® Icon™ systems. Chinese neurosurgeons perform among the highest annual caseloads globally—often exceeding 300 procedures per year—ensuring extensive technical experience. Additionally, top-tier hospitals in Beijing, Shanghai, and Guangzhou provide English-speaking coordinators and streamlined logistics for international patients.
