March 8, 2021; Tucson, AZ - Arizona Blood and Cancer Specialists (ABCS), OneOncology, and TMC HealthCare (TMC) today announced that through their joint venture, they have opened two new, free-standing centers focused on radiation oncology and advanced diagnostic imaging.
The newest facility, which opened on March 1st, is located at 3700 E. Fort Lowell Road, Suite 130, Tucson, AZ 85716. Services there will include sophisticated, integrated technologies for planning and delivering high-precision image-guided radiosurgery using Varian’s Edge™ radiosurgery system. Adding radiation oncology services will open the door for treatment options for patients who may not have had other options and will give their team of oncologists new tools for treating more types of cancer including those that are typically hard to treat.
The site will also utilize GE’s Discovery IQ system for molecular imaging. This superior technology will provide physicians with high-quality images and accurate quantitative information, giving them the ability to find and treat cancer sooner.

The second location in Green Valley that opened in the fall of 2020, is located at 121 W. Esperanza Blvd., Suite 181. In addition to medical oncology, hematology and palliative care that ABCS provides, the joint venture also expanded treatment options along the continuum of care for patients by adding radiation oncology services.
“Providing this service in Green Valley allows our patients to receive their cancer care close to their home, and without making multiple trips to Tucson to receive their radiation treatments,” said Bruce W. Porterfield, MD, Ph.D., medical oncologist/hematologist in Green Valley.
Patients receiving radiation treatment or PET/CT diagnostic imaging at the new clinics experience seamless care between their medical, surgical and radiation oncologists, and the centers’ radiation oncology treatment teams and PET/CT diagnostic imaging specialists.
“TMC HealthCare has a long history of caring for the people of Southern Arizona,” said Mimi Coomler, R.N., Chief Operating Officer, TMC HealthCare. “As a leading provider of cancer care services, we have worked with the physicians at ABCS for many years. Our joint venture with Arizona Blood and Cancer Specialists will extend and expand the oncology services our system provides. We are grateful for this partnership, and for what it will bring to our patients.”
“TMC’s history of providing exceptional healthcare aligns well with our experience, commitment, and vision of how we can positively impact patients’ lives. Our practice is proud to partner with such a well-established, and well-respected health care provider in Southern Arizona” said Robert J. Brooks, M.D., ABCS’ director of Physician Services.
