Proton Beam Therapy

Treating cancer while sparing healthy tissue.

Conventional radiation therapy.

Passes all the way through the body, affecting neighboring tissues/organs.

Proton beam therapy.

Targets the tumor and stops.

  • High-dosage radiation therapy
  • Precise delivery to tumor cells
  • Spares nearby healthy tissues/organs

This allows effective treatment of cancers in or near critical organs, reduces side effects for patients, and is especially important for treating children with cancer.

How it works.

  • Precision targeting:

    Delivers radiation directly into the tumor, leaving surrounding tissue intact.

  • Destroy the entire tumor:

    Intensity Modulated Pencil Beam Scanning, the most advanced proton beam therapy, conforms to the shape of the tumor. It scans across the tumor, essentially painting it with radiation.

  • Shattering the cancer's DNA:

    Proton beam renders the cancer cells unable to reproduce.

The science of saving lives.

  1. A proton beam starts with water.
  2. The hydrogen atom is removed from the water molecule.
  3. The atom is an electric charge.
  4. A synchrotron uses magnets to accelerate these protons to 2/3 the speed of light.
  5. Protons travel down the beam line into treatment rooms.
  6. The proton beam is delivered precisely into tumor cells.

The benefits of proton beam therapy.

  • Minimal radiation exposure to healthy tissues and organs.
  • Fewer treatments for some cancers due to higher dose per treatment.
  • Pediatric patients experience fewer long-term effects.
