Mayo Clinic's approach

Mayo Clinic experts have extensive experience using IMRT to treat many types of cancers and tumors that aren't cancerous. More than 10,000 people undergo radiation therapy at Mayo Clinic each year.

Your Mayo Clinic care team

Mayo Clinic's highly trained radiation oncology team includes radiation oncologists, radiation therapists, oncology nurse practitioners, physician assistants, oncology nurses, treatment planners (dosimetrists) and medical physicists.

Your radiation oncology team works closely with medical oncologists, surgeons, radiologists, pathologists, other medical specialists and other experts to coordinate the best care for you.

Advanced radiation treatment planning and delivery

Mayo Clinic doctors use the latest imaging techniques to carefully plan radiation treatments. Doctors use CT scans, MRI scans and positron emission tomography scans, also called PET scans, to create a treatment plan that targets just the cancer.

Proton beam therapy facilities at Mayo Clinic use intensity-modulated pencil beam scanning. This advanced treatment technology permits more-precise distribution of radiation therapy with fewer side effects for certain tumors.

IMRT is just one radiation therapy technique available at Mayo Clinic. Other radiation therapy treatment technologies include:

  • Adaptive radiation therapy.
  • Volumetric-modulated arc therapy.
  • Image-guided radiation therapy.
