Who We Are

At McLaren Proton Therapy Center, part of the Karmanos Cancer Network, we deliver the most advanced form of radiation therapy available today.

  • Radiation stops precisely at the tumor with virtually no “exit dose.”
  • Patients experience fewer side effects thanks to greater precision.
  • Highly sophisticated technology enables millimeter-level targeting.
  • The vast majority of unnecessary radiation outside the tumor is avoided.
