Why Yale Medicine?
  • We were the first in Connecticut to perform radiosurgery and have treated more patients than any other center in the state.
  • Our highly experienced team of physicians use both Gamma Knife and LINAC-based radiosurgery.
  • We are the only radiation center in the state with a radiosurgery machine dedicated to treating head and neck lesions.
  • For cancer treatment, our radiosurgery team is part of a closely knit multidisciplinary group of physicians including medical oncologists, radiation oncologists, neurologists, neurosurgeons, neuropathologists, and neuroradiologists dedicated to using front-line treatments for brain metastases.

“Brain surgery” once meant using a knife and opening the skull, and “radiation” was a treatment that sacrificed normal brain cells for the sake of killing cancerous ones.

Gamma knife radiosurgery is a noninvasive treatment for brain tumors that allows physicians to preserve most of the patient’s healthy brain tissue. This game-changing procedure has been especially effective in helping to reduce the size of metastatic tumors—tumors that develop in the brain due to cancer that has spread from another part of the body.

“When we first started doing radiosurgery more than a decade ago, patients with metastatic brain tumors were only living six to eight months, on average,” says Veronica Chiang, MD, associate professor of Neurosurgery and Therapeutic Radiology and director of Central Nervous System Radiotherapy at Yale Medicine. “Now we’re talking about survival rates in the order of years. To give these patients their best outcome and quality of life, we as physicians must work together in a coordinated fashion to make sure that we use the right treatment at the right time. The use of Gamma Knife has revolutionized our ability to keep patients well neurologically while they maximally benefit from their cancer treatments.”
