Unfortunately, there is no good treatment for patients with tumor in China, so we can consider going to Japan for proton heavy ion therapy. Many proton heavy ion hospitals in Japan, such as the East Hospital of National Cancer Research Center, the Affiliated Hospital of Tsukuba University, Nagoya Proton Center, etc., have cooperative relations with Tamaki Health. It is a very good choice to go to Japan for proton heavy ion therapy through Duomu Health.
