Kirsten, if you have the pituitary surgically removed, the pill will just replace the hormone it produces. It's not like the one that you would take to treat the tumour, I don't think.

I think surgery would be what the docs go for if the tumour has grown.

About the pituitary gland:
http://biology.about.com/od/anatomy/...tary-gland.htm
The Pituitary gland is also referred to as the "master gland". It administers the functions of the endocrine system.

The pituitary gland is involved in several functions of the body including:
  • Growth Hormone Production
  • Production of Hormones That Act on Other Endocrine Glands
  • Production of Hormones That Act on the Muscles and the Kidneys
  • Endocrine Function Regulation
  • Storage of Hormones Produced by the Hypothalamus


There is an interesting little video here about the pituitary gland and what it does. You need Adobe Shockwave Player to view it, which is free from www.adobe.com
