Why Yale Medicine?
  • On average, our teams conduct two pituitary adenoma surgeries per week.
  • Our team tries to identify mutations in each patient’s tumor using genomic analysis, bioinformatics and an in-house tumor bank.
  • Our neurosurgeons are trained to use Gamma Knife® for follow-up surgery if necessary.

There is a pea-sized gland just below your brain that controls hormone production. These hormones help control growth, blood pressure, certain functions of sex organs, thyroid glands, and metabolism. Occasionally however, those functions can be disrupted when a tumor starts growing on the gland. About 10,000 pituitary tumors are diagnosed every year, according to the American Cancer Society. And even though most tumors aren't cancerous, they can still cause serious health problems. 

At Yale Medicine, neurosurgeons, surgical endocrinologists, and neuropathologists come together to diagnose and treat pituitary tumors, using advanced diagnostic techniques and minimally-invasive procedures. “What is unique to Yale Medicine is that no one else in the country is doing detailed assays (or tests) to determine which part of the gland is responsible for tumors,” says Dennis Dee Spencer, MD, Harvey and Kate Cushing Professor of Neurosurgery and director of Yale Medicine's Epilepsy Surgery and Pituitary Tumor programs.
