    Partnership and Press Conference

    Hampton Unversity Proton Cancer Institute (Hampton Proton) has entered into a unique partnership with Leo Cancer Care to help advance research into Proton Arc Therapy (PAT).

    The partnership between Hampton Proton and Leo Cancer Care will repurpose an existing fixed-beam proton therapy treatment room and install its advanced upright patient positioning system and CT scanner.


    In August 2023, members of the Hampton Proton Team traveled to the Leo Cancer Care offices in Madison, Wisc., to meet Marie for the first time.

    What is Proton Therapy?

    Proton beam therapy is an advanced form of external radiotherapy that uses high-energy proton beams instead of photon x-ray beams or electrons. Protons are small particles of an atom, and a particle accelerator is used to speed up the protons to produce the beam.

    Why Proton Therapy?

    Fewer Side Effects For Patients
    More accurate targeting
    Treats hard to reach tumors
    Lower radiation exposure
    Greater planning flexibility
    Combine With Other Treatments
