What is the prognosis for people with pituitary tumors?
What is the prognosis for a pituitary tumor? If diagnosed early enough, the prognosis for a pituitary tumor is usually excellent. If diagnosis is delayed, even a nonfunctioning tumor can cause problems if it grows large enough to press on optic nerves, the brain, or carotid arteries (vessels that bring blood to the brain). Early diagnosis and treatment is the key to a good prognosis.
How serious is a tumor on the pituitary gland?
The presence of a pituitary tumor or the removal of one may permanently alter your hormone supply, which may need to be replaced with hormone medications. A rare but potentially serious complication of a pituitary tumor is pituitary apoplexy, when sudden bleeding into the tumor occurs. It feels like the most severe headache you've ever had.

Is pituitary adenomas cancerous?
Pituitary adenomas are benign (not cancerous) tumors that affect the pituitary gland. Even though they are benign, pituitary adenomas can cause health problems because they are close to the brain, they may invade nearby tissues (such as the skull or the sinuses), and many of them produce excess hormones. Pituitary cancers (carcinomas) are rare.

What is a pituitary adenoma?
Pituitary adenomas are tumors of the anterior pituitary. Most pituitary tumors are slow-growing and benign. They are classified based on size or cell of origin. Pituitary adenoma can be described as microadenoma, macroadenoma, and giant tumors based on size. Microadenoma is a tumor less than 10 mm, while macroadenoma describes a tumor larger than 10mm. Giant pituitary tumors are bigger than 40 mm. There are functioning pituitary adenomas in which the cell type that composes them causes increased secretion of one or multiple hormones of the anterior pituitary. Alternatively, there are nonfunctioning adenomas that do not secrete hormones, but they can potentially compress the surrounding areas of the anterior pituitary leading to hormonal deficiencies. Patients with pituitary adenoma need to be evaluated by a multidisciplinary team that should include endocrinology, ophthalmology and neurosurgery.[1][2][3]

Pituitary gland and hypothalamus. The pituitary g land and the hypothalamus are located within the brain and control hormone production. The cause of uncontrolled cell growth in the pituitary gland, which creates a tumor, remains unknown.
What happens when a tumor overproduces thyroid hormone?
When a pituitary tumor overproduces thyroid-stimulating hormone, your thyroid gland makes too much of the hormone thyroxine. This is a rare cause of hyperthyroidism or overactive thyroid disease. Hyperthyroidism can accelerate your body's metabolism, causing: Weight loss.
What is a large pituitary tumor called?
Large pituitary tumors — those measuring about 1 centimeter (slightly less than a half-inch) or larger — are known as macroadenomas. Smaller tumors are called microadenomas. Because of the size of macroadenomas , they can put pressure on the normal pituitary gland and nearby structures.

Overview
An adenoma is a benign (noncancerous) tumor. Adenomas start in the epithelial tissue, the tissue that covers your organs and glands. These tumors grow slowly and look like small mushrooms with a stalk.
Symptoms and Causes
Often, the exact cause of an adenoma is unknown. Factors that can affect your risk of adenomas include:
Diagnosis and Tests
To diagnose an adenoma, your healthcare provider will complete a physical exam and medical history. You may also need one or more imaging tests, such as a CT scan, MRI scan or PET scan.
Management and Treatment
If an adenoma is small and not causing any health complications, your healthcare provider may recommend a “wait-and-see” approach. With this approach, also called surveillance, you don’t get treatment right away. Instead, you follow up periodically with your healthcare provider.
Prevention
Some risk factors for adenomas are not controllable. However, you can improve your chances of staying healthy by getting regular health screenings. If you have a higher risk of developing an adenoma, ask your healthcare provider how often you should receive screenings.
