PITUITARY TUMOURS

 

 Pituitary tumours are almost always benign tumours. Pituitary adenoma is a benign tumour, a non-cancerous tumour or growth and will not spread to other parts of the body.

 

Pituitary tumours fall into 2 categories:

Non-secreting pituitary tumours do not release any hormones into the blood. They usually cause problems by pressing on the normal pituitary gland, preventing it from working effectively and /or become large enough to press on the optic nerves, which lie just above the pituitary gland. This affects your eyesight.

Secreting pituitary tumours cause high hormone levels in the blood. They can also press on the optic nerves if they become large enough, but they are usually diagnosed before they get to that size.

 

The most common types are:

Prolactin secreting tumour- this causes a condition called as a Prolactinoma (see Prolactinomas booklet by Pituitary Foundation)

Growth Hormone secreting tumour- this causes a condition called Acromegaly. (See Acromegaly booklet by Pituitary Foundation)

ACTH secreting tumour- this causes a condition called Cushing’s disease (see Cushing’s Syndrome booklet by Pituitary Foundation)

 

Pituitary adenoma may secrete many of the other hormones produced in the pituitary gland but the 3 listed above are the most common.

 

The type of tumour you have is determined by the blood test that your endocrinologist has done and/ or by the pathologist after your operation.

 

Pituitary tumour sized less than 1 cm is called “microadenoma”, sized 1cm to 4 cm is called “macroadenoma” and sized above 4cm is called “giant adenoma”
