A pituitary adenoma can be described using various synonyms. It is a non-cancerous tumor located in the pituitary gland, which is responsible for producing hormones that help regulate various bodily functions. The condition may also be referred to as a pituitary tumor, hypophysial adenoma, or pituitary neoplasm. The size and type of the tumor can determine the symptoms and severity of the condition. Pituitary adenomas if left untreated can cause hormonal imbalances, vision problems, and headaches. Treatment options include surgery, medications, and radiation therapy, based on the size, location, and symptoms of the tumor. Regular monitoring is necessary to prevent complications.
