Tumour of the Pituitary Gland

It often begins insidiously. Headaches that have no explanation. Visual disturbances that come and go. Hormonal fluctuations that throw everything into disarray — sleep, mood, cycle, metabolism. And then the diagnosis: a tumour in the pituitary gland. A word that pulls the ground from under your feet, even though many of these tumours are benign and grow slowly.

The pituitary gland is tiny — barely larger than a pea — and yet it controls almost everything. It sits protected in a bony hollow at the base of the skull and governs the entire hormonal balance: growth, reproduction, stress response, thyroid, adrenal glands. Medicine calls it the master gland of the body. When something grows there that doesn't belong, the entire system falls out of rhythm.
