Pituitary gland tumour is an abnormal cell growth in the pituitary gland. The pituitary gland is located behind the back of the nose that controls other glands and functions in the body. Majority of pituitary tumours are not cancerous thus benign. It means they do not spread to other body parts. However, they can cause the master gland to produce too few or too many hormones, which can affect several bodily functions.
Pituitary tumours that result in overproduction of hormones can cause other glands to produce similar amounts of hormones. These excessive substances in the body can cause abnormalities, i.e., symptoms of diseases related to each specific hormone. Also, depending on its size, a pituitary tumour can put pressure on optic nerves, causing vision issues.
