Understanding Pituitary Tumors
Pituitary tumors are abnormal cell growth in the pituitary, a small gland above the nasal passages and the soft palate (roof of the mouth), just under the brain. Connecting with the hypothalamus in the brain, the pituitary serves as a link between the brain and the glands and organs that comprise the endocrine system and produce hormones. The “master control” hormones the pea-sized pituitary produces function to regulate other hormone levels throughout the body.
A majority of pituitary tumors are noncancerous. These benign growths are known as pituitary adenomas and experience only gradual growth, not spreading to other parts of the body. Some impact pituitary functioning, causing overproduction of certain hormones and hormonal imbalance.
When pituitary tumors exceed around a half-inch in width, they run out of space and tend to grow upward, pressing on important nerves and parts of the brain. This can cause headaches and vision changes. Pituitary carcinomas, or pituitary cancers, are extremely rare. However, they can produce hormones and may spread to nearby areas such as the spinal cord, brain, bone, and meninges (the brain and spinal cord covering). In cases of cancerous tumors and those with negative symptoms, treatment operations include radiation therapy, drugs, and surgery to remove the tumor.
