Together: A Better Way To Fight Cancer

Thousands of patients trust their care to Radiotherapy Clinics of Georgia. Founded in 1984 by renowned radiation oncologist Dr. Frank Critz, Radiotherapy Clinics of Georgia today is a center of excellence in radiation treatment for cancer. We use the latest radiation technology and meticulous research to treat men and women with different types of cancer including breast, prostate, lung, colon, lymphatic and many others. Radiotherapy Clinics of Georgia is also home to the oldest and most successful prostate seed implant program in existence. We’re proud to say that our treatment for prostate cancer, ProstRcision®, has the world’s highest proven cure rate.

Radiotherapy Clinics of Georgia is part of The US Oncology Network, a community of more than 1,400 affiliated physicians with expertise in medical oncology, hematology, radiation oncology, gynecologic oncology, urology, oncology surgery and other specialties. We believe local cancer care is better care. Practices in The Network deliver advanced integrated cancer care supported by a network of independent physicians who share expertise and resources to provide quality, value-based care close to home. The Network practices have more than 400 sites of care in over 25 states and treat over 850,000 patients annually. The Network is supported by McKesson Specialty Health, an industry leader in solutions that empower the community patient care delivery system to advance the science, technology and quality of care.

Radiotherapy Clinics of Georgia began with one location in Conyers, Georgia, a quiet suburb of Atlanta. Over the years, we’ve branched out with offices throughout the metro Atlanta area. As we’ve expanded, our reputation has grown as well. Radiotherapy Clinics of Georgia has become one of the country’s top cancer treatment and research facilities, especially in the area of prostate cancer.

We have treated more than 16,000 men for prostate cancer with ProstRcision. We have compiled our observations of these men, both before and after treatment, into one of the largest computerized databases on prostate cancer in the U.S. In addition, our doctors have written more than 80 peer-reviewed research papers on prostate cancer that have been published or presented at major medical meetings. Each year, thousands of patients from across the United States and around the globe come to us seeking a cure for their cancer.
