Radiation Oncology

Radiation therapy uses high energy rays, such as X-rays, to destroy many types of cancer cells and shrink tumors in different parts of the body.  Radiation damages the genetic material of cancer cells, which stops their growth. Radiation may also damage normal cells that are close to the cancer cells. But normal cells usually repair themselves, while the cancer cells cannot.

If your doctor determines radiation is the best course of treatment for your diagnosis, you can count on receiving the latest radiation techniques and equipment with treatments delivered by an experienced team of specialists and therapists at Concord Hospital Payson Center for Cancer Care.


  • Linear accelerators (LINAC) for external beam radiation therapy
  • Prostate seed brachytherapy
  • Image-guided radiation therapy
  • Stereotactic radiosurgery
  • Large bore CT simulator

Using the latest radiation technology, the board-certified radiation oncologists on our medical staff, therapists, medical physicists, and dosimetrists collaborate to design custom treatment plans for patients.

Our multi-disciplinary team includes physicians, oncology-certified nurses, rehabilitation professionals, pharmacists, care managers, a board-certified specialist in oncology nutrition, social workers, physician-led palliative care program, and many others. This highly-effective approach ensures all aspects of your care from diagnosis through treatment are coordinated and consistent.

Our oncology nurses are nationally certified by the Oncology Nursing Society. This means they have proven their knowledge of cancer care by passing a test demonstrating an in-depth knowledge of cancer care. Before they can take the test, nurses must have experience as cancer nurses. Additionally, they must have completed the required educational programs.
