Pituitary Tumours

Pituitary Tumours - What it is


The pituitary gland is a small oval-shaped endocrine gland located at the base of the brain just behind the nose and below the optic nerve (the nerve which leads to the eyes). It is about the size of a pea and is very important because it secretes several chemical messages known as hormones.

Hormones produced by the pituitary gland helps to regulate and control the secretion of hormones from other endocrine glands which are responsible for the body’s growth, metabolism and maturation.

What is a Pituitary Tumour?

Generally, pituitary tumours are benign (non-cancerous) and slow growing. Pituitary tumours constitute 10% of primary brain tumours. Pituitary tumours are either secreting (producing hormones) or non-secreting tumours (not producing hormones). Both categories may press on structures around the pituitary fossa e.g. the optic nerve.
