Pituitary Tumors and Treatments

Living with pituitary tumor or disorders can be very challenging because an excess or deficiency of any of the hormones can adversely affect the body’s functioning. Pituitary disorders often require medical attention from a pituitary center specialist. The pituitary gland is involved in the growth, development, maintenance and reproduction processes in the body. Therefore, conditions resulting from pituitary must be taken seriously and examinations must be done to detect or diagnose pituitary disorders. At ONE Brain & Spine Center in Southern California, we offer minimally invasive surgical treatment for pituitary tumor.

Pituitary Gland

The pituitary gland is a pea-size organ that sits at the base of the brain. it is often referred to as the “master gland” because it produces important hormones that control our body functions and are vital to our existence.

Hormones Produced by Pituitary Gland

Adrenocorticotropin (ACTH)- stimulates the production of cortisol or stress hormone that helps maintain blood pressure and blood glucose levels.
Antidiuretic hormone (ADH)- regulates water balance in the body and conserves body water by reducing the amount of water lost in urine.
Follicle-stimulating hormone (FSH)- promotes sperm production in men and stimulates the ovaries to produce estrogen and develop eggs in women. Follicle-stimulating hormone works together with luteinizing hormone to allow normal function of the ovaries and testes.
Growth hormone (GH)- controls growth in childhood and maintains a healthy body in adults.
Luteinizing hormone (LH)- stimulates testosterone production in men and egg release (ovulation) in women.
Oxytocin– causes milk to flow from the breasts in breastfeeding women and also helps labor and delivery to progress.
Prolactin- the hormone that stimulates milk production in women after childbirth.
Thyroid-stimulating hormone (TSH)- helps regulate the body’s growth, energy, metabolism and nervous system activity.

Pituitary Tumors and Disorders

Most pituitary disorders results from having too much or too little of one of the hormones, sometimes from injuries. But the most common cause of pituitary disorder is a pituitary tumor. Pituitary disorders include acromegaly, Cushing’s syndrome, growth hormone deficiency and hypothryroidism. ONE Brain & Spine Center in Southern California specializes in the diagnosis and treatment of pituitary tumor and disorders.


Acromegaly is a hormonal disorder that results when the pituitary gland produces too much growth hormone (GH) in the body. Read more »

Cushing’s Disease

Excessive production of corticosteroids, the hormone that controls the adrenal glands, by the pituitary gland results in Cushing’s Syndrome or disease. However, lung cancers and other tumors outside the pituitary gland may also cause overproduction of corticotropins. Read more »


Hypopituitarism is an rare disease that occurs when the pituitary gland does not release or releases too much of its hormones. Read more »

Pituitary Tumor Treatment Options

There are several factors to be considered in deciding the right treatments for pituitary tumors at ONE Brain & Spine Center. Our team of neurosurgeon, brain surgeon and pituitary tumor specialist will customize a treament plan based on where the tumor is located, the specific hormone the pituitary gland is producing excessively, the body function or organ affected and your overall health. Initial treatments for pituitary tumors include peforming diagnostics or MRI scans and conduct blood and urine tests post-after treatment to evaluate pituitary tumor’s location and the pituitary gland’s condition. Furthermore,


Medication (drug therapy) is very effective for treating some hormone-producing pituitary tumors. The medication can stop a tumor from producing excess hormones or shrink it so it does not press on the pituitary gland or other parts of the nervous system.

Radiation Therapy

Radiation therapy is considered if the pituitary tumor is growing fast, cannot be safely and completely surgically removed because it’s located in the part of the brain where surgery is unsafe, do not shrink with medication or if it recurs after surgery.

Types of Pituitary Tumor Surgeries

Minimally invasive surgical removal of pituitary tumors is a common treatment option, specially if the tumor benign or non-cancerous and is located in the part of the brain that our neurosurgeon can safely operate to remove the tumor. Surgical removal is the best option if the medication have proven not to help, if the symptoms are causing serious health problems and affecting the nervous system, and if the tumor continuous to grow. Additonal medication may be needed to control hormonal balance. The types of surgery for pituitary tumors we provide are:
