The pituitary gland is a small, pea-sized gland at the base of the brain, yet it controls a large part of the body's hormones. Sometimes a tumor develops in it - and most of these tumors are benign (not cancerous), but they can cause troublesome symptoms by pressing on nearby nerves or by affecting hormone secretion. In this article we explain the symptoms of pituitary tumors, their types, and the available treatment options - foremost among them modern endoscopic surgery.
Symptoms
Symptoms vary by the tumor's type and size, and may include:
- Persistent, unexplained headaches, especially if recurrent
- Vision problems, such as loss of peripheral vision (the patient stops seeing the outer edges of the visual field) - one of the most important warning signs
- Hormonal disturbances depending on the tumor type: unexplained weight changes, chronic fatigue, menstrual irregularities in women, milk discharge from the breast outside breastfeeding, or changes in growth and body features
- Reduced desire or fertility problems in some cases
These symptoms overlap with many other conditions, so having them does not necessarily mean a tumor - but it does mean you need a proper medical assessment, not self-guessing.
Types of pituitary tumors
- Functioning tumors: produce excess hormones and cause symptoms according to the hormone (such as excess prolactin, growth hormone, or cortisol)
- Non-functioning tumors: do not secrete hormones but cause symptoms as they grow and press on nearby tissue such as the optic nerves
Accurately identifying the type is the basis for choosing the right treatment, and is done through medical assessment and tests.
When to see a doctor
Consult a neurologist or neurosurgeon if you have:
- Persistent, recurrent headaches that do not respond to ordinary painkillers
- Any sudden or gradual change in vision, especially peripheral vision
- Unexplained hormonal symptoms (weight change, fatigue, menstrual disturbance, milk discharge)
If sudden, severe vision loss occurs, or a very severe, sudden headache with nausea and vomiting, this is an emergency requiring immediate attention.
Diagnosis
- MRI of the brain and pituitary gland - the primary and most accurate test for the tumor's presence, size, and location
- Hormone blood tests to determine the tumor type and its effect
- Visual field testing if there is concern the tumor is pressing on the eye nerves
Treatment options
Treatment is determined entirely by the tumor's type, size, and effect, after assessment by a specialized team:
- Monitoring: some small tumors without symptoms may be followed periodically with MRI without immediate intervention
- Medical treatment: some types (such as prolactin-secreting tumors) respond to medical therapy under a doctor's supervision, decided individually
- Endoscopic transsphenoidal surgery: among the most modern, precise ways to remove pituitary tumors - the surgeon reaches the tumor through the nose with no external opening in the skull, greatly reducing pain and recovery time compared with traditional surgery
- Radiotherapy: in specific cases, as an adjunct after surgery or for tumors difficult to remove completely
The final decision on the right treatment is made after a direct assessment, and no single plan fits every case.

Frequently asked questions
Are pituitary tumors cancerous?
Usually not - most are benign (adenomas), but they need treatment if they cause symptoms or press on nearby tissue.
Does every pituitary tumor need surgery?
No - the choice depends on the tumor's type, size, and symptoms; some are monitored, some respond to medical treatment, and some need surgery.
What is the advantage of endoscopic surgery through the nose?
It reaches the tumor through the nose without opening the skull, greatly reducing pain, surgical risk, and recovery time.
Does vision recover after treatment?
In many cases, relieving pressure on the eye nerves improves vision, but this depends on the duration and severity of the pressure beforehand - early detection gives the best results.
Can the tumor come back after treatment?
There is a possibility in some cases, which is why periodic follow-up with MRI and hormone tests is an essential part of the long-term plan.
