About me

Dr. Mack Roach III is a radiation oncologist and an internationally renowned expert on treating and managing prostate cancer.

Roach's research investigates new techniques for treating prostate cancer, such as 3-D conformal radiation therapy, in which the beam is matched to the tumor's shape, sparing healthy tissue, and intensity modulated radiotherapy (IMRT), in which radioactive particles are inserted into the prostate gland, beside the cancer. He also studies such established treatments as brachytherapy. He chaired an important clinical trial comparing strategies for locally advanced prostate cancer.

Roach earned his medical degree at Stanford University School of Medicine.

A global authority on treatment planning for prostate cancer, Roach served as senior author for the American College of Radiology's guidelines on the subject. He is a member of several professional organizations, including the American Society of Clinical Oncology, American Society for Therapeutic Radiology and Oncology, Radiation Therapy Oncology Group, National Cancer Institute's IMRT Working Group and American Joint Commission for Cancer Staging.
