The Maryland Proton Treatment Center (“MPTC”) is a leading edge cancer center that brings a highly advanced form of cancer treatment - proton therapy - to Baltimore, the State of Maryland, Washington, DC, Delaware and Northern Virginia.

This center features five treatment rooms housed in an 110,000 square-foot facility in the University of Maryland BioPark on the University of Maryland, Baltimore campus. This outpatient facility will also feature ground floor retail and includes space for research and training.

Maryland Proton Treatment Center Q&A

About proton therapy:

Proton therapy is a highly advanced form of radiation treatment that has the ability to provide cancer patients positive clinical outcomes, shorter treatment times and substantially fewer side effects or complications.

Proton therapy uses accelerated subatomic particles (protons) to precisely treat cancerous tumors throughout the body. It is more precise than conventional forms of radiation treatment, delivering an exact, high dose of radiation to a tumor while sparing surrounding healthy tissue from damage.

In contrast, the efficacy of conventional radiation therapy (such as photon/x-ray therapy, gamma ray or brachytherapy), which is used in approximately 60% of all cancer cases, is often limited because of its inability to deliver a sufficient "dose" of radiation into a tumor to destroy it and still avoid damage to the surrounding healthy tissue. That's why proton therapy can offer a more effective alternative in treating many cancers with fewer complications.

"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."
