Frequently Asked Questions
Is a pituitary adenoma cancerous?
No, the vast majority of pituitary adenomas are benign, noncancerous tumours; they can still cause significant effects through hormone overproduction or pressure on nearby structures, but they don't spread to other parts of the body like a malignant tumour would.
Will every pituitary adenoma need treatment?
No, small, non-functioning adenomas found incidentally are often simply monitored with periodic imaging, while larger tumours, those causing visual problems, or hormone-producing ones typically need medication, surgery, or radiation.
Can medication alone shrink a pituitary adenoma?
Yes, particularly for prolactin-producing adenomas, specific medications can effectively shrink the tumour and control excess hormone production, sometimes avoiding the need for surgery altogether.
How is a pituitary adenoma removed if surgery is needed?
Surgical removal is typically performed through the nose using minimally invasive techniques, which avoids the need for open brain surgery in most cases.
Why do some pituitary adenomas cause vision problems?
Larger tumours can grow upward and press on the nearby optic nerves that cross just above the pituitary gland, which is why visual disturbances, particularly loss of peripheral vision, are a recognized symptom of larger adenomas.
