A person with pituitary cancer might experience headaches, diabetes insipidus, optic nerve damage, and more. However, those with the disease can be asymptomatic.
However, they can cause the pituitary gland to over- or under-produce some hormones, causing health issues throughout the body.
Research indicates that

Pituitary tumors are mostly benign and are called functioning pituitary adenomas. This means they secrete extra hormones in a person’s body,
The
Rarely, pituitary adenomas can become cancerous and spread into other areas of the brain, spinal cord, or outside the central nervous system.
The tumor might also continue to produce mainly adrenocorticotropic hormones and prolactin hormones.
The Genetic and Rare Diseases Information Center (GARD) explains that an individual with pituitary cancer may experience the following symptoms:
- headache
- Cushing’s syndrome
- increased prolactin levels
- malignant neoplasm of the central nervous system
- enlarged pituitary gland
- hemianopia, or partial or complete vision loss
- hypopituitarism, when the pituitary gland does not make enough of certain hormones
- hyperpituitarism
- progressive visual field defects
- abnormality of central motor function
- ataxia, a lack of muscle coordination
- acromegaly, a rare condition that results from excessive growth hormone in the body
- growth hormone-secreting adenomas
- diabetes insipidus, where the body loses too much fluid through urination
- pituitary gonadotropic cell adenoma
- hyperthyroidism, when the thyroid gland produces too much hormone

The symptoms above can lead to the following secondary symptoms:
- weight gain
- bruising easily
- flushed skin
- seizures
- issues with muscle and bone strength
- irritability, anxiety, and depression
- nausea and vomiting
- dizziness
- confusion
- lactating when not pregnant
- low milk production when breast-feeding
- menstrual cycle changes
- low libido
- high blood pressure
- irregular heartbeat
- large hands and feet
- erectile dysfunction
- body hair loss
- atypical sexual development and growth in children
- vision issues
If a person with pituitary cancer does not receive treatment, it can decrease their quality of life or likelihood of survival.
An individual might require surgery to remove the tumor. However, the risks of having surgery include vision problems from nerve damage, heavy bleeding, and further damage to the pituitary gland.
Other rare complications, such as meningitis and cerebrospinal fluid leaking from the brain out of the nose, can also occur.
The appropriate treatment can correct these complications. Additionally, pituitary cancer or its treatments do not always cause long-term health issues.
According to a
Treating pituitary cancer
Experts typically recommend a combination of surgery and radiation therapy as treatment methods.
A doctor may also recommend chemotherapy, particularly when surgery and radiation are not possible or were previously unsuccessful in a person’s treatment.
These treatments may alleviate someone’s symptoms to some extent. Other medications and lifestyle changes may improve the outlook and quality of an individual’s life.
A person should discuss ways to manage their symptoms with a medical professional.
This section answers some frequently asked questions about pituitary cancer symptoms.
How is pituitary cancer diagnosed?
Generally, MRI or CT scans can detect tumors in the pituitary gland. Blood and urine tests can also determine hormone levels in an individual.
However, even when using a microscope to diagnose pituitary cancer, experts may find it hard to distinguish between a cancerous and a noncancerous pituitary tumor.
Experts may not recognize a cancerous tumor until it spreads into another part of a person’s body.
Pituitary cancer spreads equally to areas both inside and outside the brain. The tumor is likely to spread in many distant areas of an individual’s body, including:
- other parts of the brain and brain blood vessels
- the spinal cord
- the eyes
- the lymph nodes
- certain organs, such as the lungs, heart, liver, pancreas, kidneys, and ovaries
Is pituitary cancer curable?
When a pituitary tumor is cancerous and spreads to another part of the body from where it started, doctors refer to it as a metastatic cancerous tumor.
At this advanced stage, it is harder for medical professionals to cure or control the disease, and an individual’s prognosis is generally unfavorable.
The National Cancer Institute’s Surveillance, Epidemiology, and End Results database indicates that someone with pituitary cancer that has metastasized has a 5-year relative survival rate of
This means that, on average, those with a metastatic pituitary gland cancer diagnosis are 30% as likely to live at least 5 years after their diagnosis as people without the disease.
GARD indicates that the most common pituitary cancer symptoms are headaches, optic nerve dysfunction, diabetes insipidus, and anterior pituitary dysfunction.
However, people with pituitary cancer may be asymptomatic.
The outlook is generally unfavorable, as a person is likely to receive a diagnosis at a late stage when the cancer has metastasized.
This is due to the difficulties in recognizing the difference between a cancerous and a noncancerous pituitary tumor.
However, a doctor and
