Doctor with patient

Radiation therapy is a form of cancer treatment that is used to shrink tumors. It kills cancer cells by using high-energy beams that damage their DNA, making them unable to divide, so they die.

The Department of Radiation Oncology at The Tate Cancer Center at UM Baltimore Washington Medical Center offers the most advanced radiation therapy treatments at a convenient location in Anne Arundel County.

Modern advanced technology makes radiation therapy more efficient and safer than ever. Our technologies use pinpoint accuracy to minimize damage to surrounding tissue and organs, and treatments are usually done in an outpatient setting with some lasting just a few minutes.

Working with experts from medical and surgical oncology along with other members of the radiation oncology department, our radiation oncology team creates unique treatment plans for each of our patients, carefully considering all treatment options in order to give you the best chance for successful results.

Therapies and Technology

At the Tate Cancer Center, our radiation oncologists use the best technology available for treating tumors.

Our team of specialists, which includes radiation, medical, and surgical oncologists, collaborate and create an individualized treatment designed to deliver the best possible outcome for you. The care team will recommend a specific type of radiation therapy, which would depend on your specific cancer. This may include the following:

  • External beam radiation therapy is the most common type of radiation therapy used for cancer treatment. A machine is used to aim radiation beams from outside the body into the tumor. The machine we use is a Varian linear accelerator.
  • Intensity modulated radiation therapy (IMRT) is a more advanced version of 3D-conformal radiation therapy. By changing the intensity of the beams it delivers a more precise dose of radiation to the tumor while further reducing the amount of radiation to surrounding healthy tissue.
  • High-dose-rate (HDR) brachytherapy (sometimes referred to as internal or intracavitary radiotherapy) involves placing radioactive sources in or next to the cancer.
  • Stereotactic radiosurgery (SRS) is not surgery, but a very precise technique used to deliver radiation to cranial and spinal tumors with a very fine and ultra-precise radiation beam. These treatments usually are delivered in one to five sessions versus over the course of several weeks when compared to normal external beam radiation therapy.
  • Stereotactic body radiotherapy (SBRT) is the same as SRS except it is used to treat sites outside of the cranium and spine.
  • Image-guided radiation therapy (IGRT) x-rays are used to accurately align the patient prior to treatment based on each individual patient's internal anatomy.

Patients at the Tate Cancer Center also have access to an even larger team of radiation oncology experts and state-of-the-art treatments available at the University of Maryland Marlene and Stewart Greenebaum Comprehensive Cancer Center (UMGCCC) and the Maryland Proton Treatment Center (MPTC). These include therapies not often found elsewhere, such as:

These additional tools help ensure that you can receive a treatment plan that's ideal for your situation. Should you require radiation treatment at either UMGCCC or MPTC in downtown Baltimore, you will receive free valet parking with our complimentary Concierge Program. One of our team members will also meet you at the front door to escort you to your first appointment.
