At the University of Michigan, he began research in cancer immunology and continued this at the University of Chicago where he completed his residency training in Radiation Oncology in 1997. He remained at the University of Chicago as both a National Cancer Institute research fellow in cancer immunology and then on staff specializing in the treatment of lymphomas and pediatric oncology.

During his time in Chicago, he published on a number of cancer subjects including the treatment of prostate cancer, lymphomas, and 3D conformal radiation treatments.

Since arriving in Arizona, Dr. Yang has embraced the latest technologies in the treatment of some of the most difficult oncology cases. He was one of the first radiation oncologists in Arizona to use Intensity Modulated Radiation Therapy (IMRT)–a more precise way of shaping the beams of radiation to conform to the target disease–in the treatment of head and neck cancers with great success. He is proud of the large number of head and neck patients that continue to follow up with him for many years. In addition, many of his patients have benefited from Stereotactic Radiosurgery (SRS) procedures for both brain and body tumors (particularly lung cancer), which is able to deliver high doses of pin-point radiation to small cancers in less than one week. In addition, Dr. Yang has many years of experience with High Dose Rate (HDR) brachytherapy for implantable malignancies, which allows high doses of radioactive material to be temporarily placed next to the cancer while minimizing dose to the surrounding organs.

Although adopting advanced technology has played an important role in developing his practice in Arizona, Dr. Yang believes strongly that educating the patients and their families is the first step towards a successful outcome. Time and patience for those in need is an essential component in his treatment of cancer patients.
