Pituitary adenoma is relatively common and typically benign and localized. It grows slowly from cells in the pituitary gland, which regulates the body’s hormones.

This type of tumor usually remains small without causing significant symptoms. When it does progress, however, it can cause vision, growth and hormone problems.

While a definitive cause remains unknown, medical science has linked pituitary adenoma to endocrine disorders, genetic changes, family history and exposure to radiation and other substances that promote cancer. Like its symptoms, its treatment depends on size and location, along with the patient’s overall health and age.

Symptoms

• Headache
• Blurred or tunnel vision
