What is a Radiation Oncologist?

"What is a Radiation Oncologist?" With Dr. Mutyala

Radiation oncologists are doctors who specialize in using radiation therapy to treat patients with cancerous and noncancerous tumors. Radiation therapy uses high-powered X-rays, seeds or radioactive material to shrink or destroy tumors.

Scott & White's radiation oncologists combine extensive experience and research with the most advanced technology to precisely target and treat tumors, while sparing surrounding healthy tissue and organs, and decreasing side effects. We perform thousands of radiation treatments a year for patients in need of compassionate cancer care.

Scott & White also promotes a collaborative environment for referring physicians. Our collaborative, patient-centered approach helps ensure you receive excellent cancer care.

Types of Radiation Therapy

Scott & White offers the following types of radiation therapy:

Accelerated Partial Breast Irradiation (APBI)

SAVI Advantages
  • Minimizes exposure to health tissue without sacrificing the treatment

  • Reduces treatment time from seven weeks to five days

  • Extends the benefits of accelerated partial breast irradiation to more women

  • Allows for customized treatment plans specific to each tumor type and location

The Department of Radiation Oncology has recently been designated as a Center of Excellence in Accelerated Partial Breast Irradiation (APBI). APBI is a non-surgical course of high-dose radiation for early stage breast cancer patients following lumpectomy surgery. It delivers radiation from inside the breast, which ensures the radiation dose is delivered only to the tissue immediately surrounding the tumor and minimizes exposure to healthy tissue. This targeted treatment reduces treatment time from seven weeks to five days.

The APBI treatment is delivered through a SAVI applicator, which is a multi-catheter device that allows the physician to customize the doze based on the size and shape of the tumor.

In order to be selected as a Center of Excellence, Scott & White completed a comprehensive training and education program and displayed expertise in offering this technology to women diagnosed with early stage breast cancer.

External-Beam Radiation Therapy

In this cancer treatment, high-powered X-rays are directed at your tumor from an outside source. With careful planning and advanced image guidance, we're able to destroy cancer cells without damaging surrounding healthy tissues.

  • Intensity-Modulated Radiation Therapy (IMRT)
  • Three-Dimensional Conformal Radiation Therapy (3DCRT)
  • Stereotactic Radiotherapy using the Novalis Tx Radiosurgery Platform

Internal-Beam Radiation Therapy (Brachytherapy)

Also called brachytherapy, internal-beam radiation therapy is "short distance" therapy where minimally invasive techniques are used to place radioactive material inside your body, directly in or close to the area being treated. A prostate seed implant (prostate brachytherapy) is one example.

Placement of the radioactive material may be temporary or permanent.

Scott & White offers several types of internal-beam radiation therapy, including:

  • Low-Dose Radiation Therapy
  • High-Dose Radiation Therapy
    • Intracavitary Implants
    • Interstitial Implants
    • Endobiliary Brachytherapy
