Washington Cancer Institute is a national leader in radiation therapy for the treatment of many cancers. Expert care is provided by the most experienced radiation oncology team in the Washington, D.C., metro area, and the most advanced technology, providing the best chance for healing and recovery. 

About half of all cancer patients receive some type of radiation therapy during the course of their treatment. Radiation therapy is a type of cancer treatment that uses beams of intense energy to kill cancer cells.  

As the first hospital in Washington, D.C. to offer the Varian Trilogy Stereotactic System, we provide many state-of-the-art and emerging radiation technologies that deliver the latest, safest and most effective technological advances to treat cancer.

Advanced Radiation Technology

By using the latest treatment planning technology to map precise tumor locations, our expert radiation oncologists develop treatment plans with pinpoint accuracy. This ensures that tumors get the most effective dose while sparing healthy tissues and organs. Our wide range of sophisticated medical equipment allows us to treat tumors aggressively and also reduce some of the side effects of radiation treatment.

Radiation treatment can be delivered by a machine outside the body using external-beam radiation therapy, or it can come from radioactive material placed in the body near cancer cells using internal radiation therapy, also called brachytherapy. Systemic radiation therapy uses radioactive substances, such as radioactive iodine, that travel in the blood to kill cancer cells.

Here are some of the many technologies that may be part of your care if you are a cancer patient:

  • Advanced computerized treatment planning, fusion and verification systems
  • Brachytherapy, including high-dose rates (HDR) and low-dose rates (LDR)
  • Image-guided radiation therapy (IGRT) with cone beam CT and kilovoltage imaging (KV) for improved target localization
  • Intensity-modulated radiation therapy (IMRT)
  • Partial breast irradiation with both external beam therapy and brachytherapy
  • Positron emission tomography and computed tomography (PET/CT) simulation
  • Respiratory gating
  • Sophisticated 4-D large bore computerized tomography (CT) simulator (GE Discovery)
  • Three state-of-the-art linear accelerators
  • Total skin electron irradiation (TSEI), the region's only location for this type of treatment

Radiation therapy most often gets its power from X-rays, but the power can also come from protons. The type of radiation depends on your individual cancer treatment plan.

Radiation Oncology Services

Washington Cancer Institute features a radiation oncology patient suite located on the ground floor of the Washington Cancer Institute. The suite offers a convenient, comfortable and healing environment for patients when they come for treatment at MedStar Washington Hospital Center. 

Patients undergoing radiation therapy receive quick patient evaluations and consultations with our physicians who keep your referring physician up-to-date as we develop and begin treatment.

The radiation oncology program also provides a network of compassionate support services to help overcome the challenges of treatment and recovery. Numerous patient education and support programs and assistance from nutritionists, social workers and pastoral counselors are available to all of our patients. There are also support programs and resources for family members and loved ones.
