Jonathan Cheng

Dr. Jonathan Cheng is a radiation oncology specialist practicing in Baytown, Texas. He specializes in general radiation oncology, breast cancer, cervical cancer, gynecologic cancer, vulvar cancer, lung cancer, and colorectal cancer.

Graduating from the University of California, Los Angeles, Dr. Cheng received his medical degree from the Keck School of Medicine at the University of Southern California (USC) before going to City of Hope Medical Center for his residency training. Dr. Cheng performs such procedures as brachytherapy, stereotactic radiosurgery, and image-guided radiation therapy (IGRT). Brachytherapy is an advanced treatment option involving the insertion of radioactive implants directly into cancerous tissue, allowing localized, precise doses of radiation to reach targeted areas in the body. Stereotactic radiosurgery is a non-surgical treatment option to treat small tumors by delivering smaller, targeted doses of radiation. Finally, IGRT uses imaging technology to direct radiation to a particular area.

Dr. Cheng's approach of treatment focuses on the diagnosis, treatment, and prevention of gastrointestinal growths. Dr. Cheng is affiliated with the Altus Cancer Center and is a leading expert in radiation oncology in the Baytown area.
