At UT Southwestern Medical Center, our team of radiation oncologists treats more than 3,600 people with cancer each year. Our patient-centric focus combined with state-of-the art technology means patients can expect the best treatment possible.

We are the only National Cancer Institute (NCI)-designated comprehensive cancer center in North Texas and one of only 49 NCI-designated comprehensive care centers in the nation. As such, we are held to the highest of standards and are recognized for excellence in clinical care, as well as scientific research and leadership. 

Our radiation oncologists have specialized training in radiation treatment and are board-certified by the American Board of Radiology. Our team helped pioneer stereotactic ablative radiotherapy (SAbR)/stereotactic body radiation therapy (SBRT), a revolutionary technique that has been shown to offer better cure rates – particularly for cancer that has metastasized. And we treat all types of cancer, including:

Our radiation oncologists work closely with radiation physicists, radiation biologists, dosimetrists, radiation therapists, nurses, dietitians, and other clinical staff to ensure each patient receives the most comprehensive and thorough care possible. In addition, clinical care is divided into disease-oriented teams so that patients receive care by those who specialize in their specific cancer. We also offer palliative radiation therapy to help ease the side effects of treatment or pain. As with all of UT Southwestern, we are committed to transparency in reporting our experiences and outcomes.

Breast Cancer

Breast cancer is the most common cancer in women and will affect one in eight women during her lifetime. At UT Southwestern, we offer multidisciplinary care, including a breast-specific tumor board, that brings all specialists (radiation oncologists, surgeons, medical oncologists, radiologists, pathologists, and genetic counselors) under one roof to devise the best treatment plan for each patient. Our breast cancer team, led by Asal Rahimi, M.D., also offers multiple cutting-edge radiation clinical trials.

What sets us apart?

We have the most comprehensive deep inspiration breath hold (DIBH)-based cardiac-sparing radiation treatment program in North Texas for patients with left-sided breast cancer including:

  • Two Vision RT surface image-guided systems dedicated for patients requiring left breast radiation treatments
  • Two Active Breathing Coordinator (ABC) machines used to monitor patients requiring breast/chest wall and lymph node treatments
  • Ongoing, active research in deep inspiration breath hold (DIBH)-based cardiac-sparing radiation treatment delivery

We also have one of two GammaPods in the world and the only one in Texas, and we are one of the few departments in the world that has a Stereotactic Partial Breast Irradiation Program. Additionally, we have the largest published clinical trial experience in this protocol.

Breast Program Overview

We offer comprehensive, patient-focused breast cancer treatment using the latest techniques, therapies, and technology. Our team includes some of the best breast cancer specialists in the world who have dedicated their entire clinical practice to treating breast cancer. Here Asal Rahimi, M.D., head of our breast team, explains our approach in treating breast cancer. 

Central Nervous System (CNS) Cancers

The CNS team, led by Zabi Wardak, M.D., works alongside neurosurgery specialists as well as radiation oncology physicists, biologists, dosimetrists, therapists, and various other dedicated clinical staff. Our disease-site-specific team treats a higher volume of patients than any other center in North Texas.

What sets us apart?

  • Both malignant and benign brain tumors are treated on our Gamma Knife Icon – the newest Gamma Knife and the only one of its kind in the Dallas-Fort Worth area – or the CyberKnife M6, both of which deliver increased protection to patients and highly focused radiation to tumors.
  • The Icon doesn’t require head restraints as used in previous models, allowing for a better patient experience. Additionally, treatments are less restricted with the Icon as we’re able to spread out the treatments in smaller doses, which is better-tolerated by normal tissues. For patients with multiple tumors, we’re able to spread treatments over the course of several days.
  • Our CNS-specific nursing team is specially trained to care for and screen calls from CNS patients.

Our CNS team treats all types of malignant and benign brain and spinal cord tumors in both pediatric and adult patients. In this video, Zabi Wardak, M.D., head of our CNS team, explains our approach in treating CNS cancers.

Gastrointestinal (GI) Cancer

Gastrointestinal cancer, which includes any cancer that starts in the digestive system, can be particularly challenging to treat. Our GI team offers the most modern technologies in treating gastrointestinal cancers, including 3-D conformal radiotherapy, intensity-modulated radiation therapy (IMRT), and brachytherapy, and we offer comprehensive care for people with all types and stages of GI cancer.

What sets us apart?

  • Our comprehensive stereotactic body radiation therapy (SBRT) program offers multiple open protocols for pancreatic cancer, treatment of primary and metastatic cancers of the liver (the latter in as few as a single treatment), and definitive treatment of cholangiocarcinoma in coordination with our liver transplantation program.
  • Our advanced intraoperative radiation therapy program is available to assist our surgical teams in the management of locally advanced and recurrent gastrointestinal malignancies. 
  • We are one of the few radiation oncology programs in the country that offers interstitial brachytherapy for liver lesions (primary cancer on protocol, metastatic as standard of care).
  • Our palliative brachytherapy program for esophageal cancer, malignant obstructive biliary disease, and rectal cancer.
  • We have site-specific tumor boards for liver and pancreatic cancers and general tumor boards for GI malignancies affecting both thoracic and abdominal/pelvic sites.

Genitourinary (GU) Cancer

Led by Raquibul Hannan, M.D., Ph.D., our genitourinary team cares for all GU cancers and offers a variety of treatment options, including stereotactic body radiation therapy (SBRT), RapidArc intensity-modulated radiation therapy, image-guided radiation therapy, HDR and LDR brachytherapy, and CyberKnife. Treatments are chosen and individualized to each patient based on their specific disease and baseline symptoms. Our multidisciplinary groups work together to not only treat patients, but to better address side effects. 

What sets us apart?

  • We offer SBRT for kidney cancer for both primary and metastatic sites.
  • For prostate cancer patients, we offer SpaceOAR, a gel that increases the space between the prostate and rectum during radiation therapy. The goals are to reduce the sexual side effects after treatment and radiation to the lining of the rectum. Our team, an early adopter of the gel, is now a leading training site for other centers wanting to bring this technology to their center.
  • A variety of GU clinical trials – most of which were designed here at UT Southwestern – including several for prostate and kidney cancers. Clinical trials are crucial to investigate new applications of emerging technology to improve outcomes in high-risk diseases and to reduce side effects in groups at lower risk.

Gynecologic Cancer

Kevin Albuquerque, M.D., head of our gynecology cancer team, specializes in internal radiation therapy (brachytherapy) – in particular, interstitial brachytherapy – one of the few centers in North Texas to offer this specialty. Based on a patient’s needs and specific cancer, we offer both inpatient and outpatient high-dose-rate brachytherapy. 

What sets us apart?

  • Brachytherapy is preferred for most gynecologic cancer sites and organs because of their proximity to the vagina where we can use special instruments internally to get closer to the tumor. Combined with the high doses of radiation, this means we’re able to kill the tumors faster. 
  • Brachytherapy has been shown to improve the outcome in patients with advanced cervical cancer and reduced associated complications. 
  • We offer MRI-guided brachytherapy – a technique offered at few other centers.
  • We have radiation treatment options for patients with uterine cancer that are unable to have surgery.
  • Stereotactic radiation therapy is available for select recurrent gynecologic cancers.
  • We offer access to regional and national gynecological cancer clinical trials.

Treatment corridor


Lymphoma (cancer of the blood cells of the immune system) can affect any part of the body where lymph nodes normally exist. Our team of medical oncologists, bone marrow transplantation specialists, radiologists, radiation oncologists, pathologists, nurses, and care coordinators work together to give the best possible multidisciplinary treatment options to each individual patient. Kiran Kumar, M.D., M.B.A., leads the radiation oncology arm of the team. 

What sets us apart?

  • Total skin electron therapy for advanced cutaneous lymphoma
  • Low-dose radiation response-based treatment for cutaneous lymphomas and indolent B-cell lymphomas, which allows us to reduce dose, treatment time, and side effects
  • Deep inspiration breath-hold treatment of chest sites of lymphoma, which helps reduce dose and long-term side effects to the heart and lungs
  • Clinical trial of total skin electron therapy combined with immunotherapy for advanced T-cell lymphoma
