Joseph Tung-Chieh Chang, MD,MHA, is a board-certified radiation oncologist, sub-specializing in head and neck cancer especially for nasopharyngeal carcinoma, breast cancer and gastrointestinal cancers. He is the chairman of the Department of Radiation Oncology and Director of Proton and Radiation Therapy Center, Chang Gung Memorial Hospital (CGMH) at Linkou. The department is the largest in the nation. The proton facility will serve the patients since fall of 2015. The first MRI-simulator in Taiwan starts in Spring of 2016.
Dr. Chang got his MD degree at Taipei Medical College in 1989 and master of health administration in Chang Gung University in 2003. He completed his 4-year residency training at Chang Gung Memorial Hospital, got the clinic professor in 2008 and became the chairman of the department in 2014. He and his colleges have dedicated their lives to the research and development of cancer radiation treatments, particularly in the subject of head and neck cance, nasopharyngeal carcinoma, breast cancer, health related quality of life and liver cancer. Up to date, Dr. Chang has successfully treated over 8,000 patients and published more than 200 peer-reviewed papers.  

He does not only an active member of Taiwan and international clinical professional societies but also a member in Psycho-social societies. Dr. Chang does not only emphasize in cancer control but also put his effort in the issue of life quality. He wants his patients live in good life but not only long life.

Successful Cases

More than thousand cases of head and neck cancer (including nasopharyngeal cancer patients). The achievement do not provide the patients with tumor control but better health related quality of life for patients.
