Proton Therapy

at the Maryland Proton Treatment Center in Baltimore, MD

The Maryland Proton Treatment Center (MPTC) offers proton therapy, which is a highly advanced and precise form of radiation for cancer patients. This therapy is highly effective for a wide variety of localized tumors. Since proton therapy delivers an increased radiation dose that stops specifically at the tumor site, it protects much of the surrounding, normal tissue. It is easily tolerated, non-invasive and often times results in fewer side effects. At MPTC, our core mission is excellence in patient care and we are honored to offer our expertise to achieve the best outcomes for our patients.

Proton therapy is a precise form of radiation for the treatment of solid tumors. Unlike X-ray (photon) technology, protons deliver a maximum radiation dose that stops at the tumor site. This enables our physicians to target the cancer cells while sparing normal, healthy tissue in the rest of the body.


MPTC is only the second facility in the US to feature pencil-beam scanning in every treatment room. This technology allows physicians to “paint” the radiation onto the tumor, layer-by-layer. The Center also features dedicated research capabilities and will have a multitude of active, clinical trials for patients to enroll in.


The Center is led by nationally-recognized University of Maryland radiation oncologists who are inspired by patients and driven by a passion for healing. Using a team approach to care, every patient receives an individualized treatment plan as well as personal concierge services to ensure a seamless experience.

About Proton Therapy

Proton therapy is a powerful tool in the toolbox in the fight against cancer. It is an advanced and precise form of radiation therapy which decreases excess radiation to the healthy cells and vital organs in the body.

During this daily outpatient treatment, a beam of protons is delivered to the patient in accordance with their customized plan. Since it is painless and results in fewer side effects, patients can continue with normal activities such as work and school during treatment.

Proton therapy is a highly effective treatment for a wide range of localized tumors such as those found in the brain, base of skull, head and neck area, eye tumors, tumors of the esophagus, lung, prostate, liver, breast and spinal cord, as well as gastrointestinal malignancies. It is also a very important treatment option for children with cancer.

Benefits of Proton Therapy for Cancer Treatment:

  • Precise form of radiation treatment for solid tumors
  • Non-invasive outpatient treatment, leaving patients with
    minimal discomfort and the ability to carry on with their daily lives
  • Better tolerated than conventional radiation treatment because of fewer acute side effects
  • Can be combined with other cancer treatments such as chemotherapy

“Proton therapy is a kind of radiation used to treat cancer. Like other types of radiation, proton therapy kills cancer cells and stops them from growing. Unlike other types of radiation therapy that use X-rays to destroy cancer cells, proton therapy uses a beam of special particles called protons. Doctors can better aim proton beams onto a tumor, so there is less damage to the surrounding healthy tissue. This allows doctors to use a higher dose of radiation with proton therapy than they can use with X-rays. Because it causes less damage to healthy tissue, proton therapy is often used for cancers that are very close to critical parts of the body.” – National Institutes of Health

About the University of Maryland

The University of Maryland Department of Radiation Oncology will operate and manage MPTC to make this advanced form of radiation therapy accessible to patients in the region and throughout the world.

Our relationship provides patients not only with state-of-the-art treatment in the forms of and intensity-modulated and image-guided proton therapy (IMPT and IGPT), but in all other aspects of radiotherapy services, including treatments such as conventional radiotherapy, brachytherapy, radiosurgery, stereotactic radiotherapy, thermal therapy, radioembolization (SirSpheres) and intensity-modulated and image-guided radiotherapy (IMRT and IGRT). In addition, all patients will have full access to a wide range of clinical trials at MPTC.

Additionally, from start to finish, patients referred to the Maryland Proton Treatment Center will be met and assisted by a dedicated concierge team member during their visit to ensure a positive experience throughout their treatment.
