Radiation Therapy

Approximately half of all cancer patients undergo radiation therapy as part of their treatment. Radiation is usually the primary treatment for cancers of the head and neck, lung, bladder, and Hodgkin lymphoma. Radiation therapy is one facet of the overall treatment for cancers of the breast, prostate, colon, cervix, uterus, gallbladder, eye, and esophagus.

Unlike chemotherapy, radiation therapy is considered a local treatment. Only cancer cells in the area where the radiation is delivered are killed. If cancer cells exist outside the area where radiation is targeted, the radiation does not impact them.

The Radiation Treatment Process

To begin your radiation treatment, you will meet your physician and radiation therapy team. Every part of your treatment is planned in advance. We’ll do imaging scans and virtual simulations to determine the correct positions on your body for treatment. Once those have been determined, small reference marks may be made on your skin to ensure correct positioning at each treatment session.

The number of treatments and the length of each session depend on your cancer type and the type of treatment prescribed.

Radiation therapy targets the precise area of the cancer tumor and can be delivered either externally or internally.

Texas Oncology offers patients an arsenal of the most effective, leading-edge radiation therapies; see a snapshot of the technologies available.

External Beam Radiation Therapy

External radiation therapy focuses a high-energy X-ray or electron beams at specific points on your body where the tumor is located.

Internal Radiation Therapy

Internal radiation therapy (brachytherapy) is a type of radiation therapy that uses sealed containers of radioactive material placed close to or inside the tumor.

Treatment Planning and Simulation

Treatment planning and simulation are the first steps in radiation therapy.

Research Collaboration

National clinical trials are also available for radiation therapy.
