Pituitary tumours (adenomas) are abnormal growths on the pituitary gland (gland controlling the growth and development of the body) . Secreting pituitary tumours are those which secrete hormones, causing hormonal imbalance in the body.

The exact cause of pituitary tumours is unclear. However they may be caused by changes in the genes which lead to abnormal growth of tissues on the pituitary gland. Tumour growth can occur at any age, but they are usually more prevalent in older age.

Secreting tumours include:

Prolactinoma is pituitary tumour which causes over-production of the hormone prolactin
Growth hormone-secreting tumour leads to acromegaly and gigantism
Adrenocorticotropic hormone-secreting (ACTH) tumour produces adrenocorticotropin, which stimulates the adrenal glands to produce hormone cortisol resulting in Cushing’s Syndrome
Thyroid stimulation hormone (TSH) - secreting tumours causes over-production of the thyroid-stimulating hormone which triggers the thyroid gland to make too much of the hormone thyroxine
