Advanced, Life-Changing Cancer Treatment with Proton Therapy in Maryland
What is Proton Therapy?
Proton therapy is an advanced form of radiation that precisely targets tumors with a maximum radiation dose that stops at the tumor site, sparing surrounding healthy tissue and organs. This non-invasive cancer treatment is especially effective for localized, solid tumors near critical organs in both adults and children.
Because of its precision, proton therapy results in far fewer side effects, including a reduced risk of second cancers caused by radiation exposure.
As part of an advanced cancer treatment approach, it helps preserve your quality of life so you can get back to it faster.

How Does Proton Therapy Work?
The Maryland Proton Treatment Center (MPTC) is one of only a few proton therapy facilities in the country that feature advanced pencil beam proton therapy technology in every treatment room.
With this cutting-edge delivery method and intensity-modulated proton therapy (IMPT), we can deliver the correct dose exactly where needed. IMPT “paints” radiation layer by layer, hugging the tumor’s shape and minimizing the dose to nearby healthy tissues.
Proton therapy is a painless, non-invasive cancer treatment that’s well tolerated and can be used alongside other therapies such as hyperthermia, chemotherapy, immunotherapy or surgery.
Compared to traditional photon radiation, it results in fewer side effects and can reduce the risk of secondary cancers by 26–39%.
