The Operation: Surgery Live S01E04 - Pituitary Tumour Removal

Christine had a tumour at the base of her brain in her pituitary gland. This is the body's hormone control centre and the tumour had affected it, causing her body to secrete an excess of growth hormones. Christine's lips had swollen and her shoe size had increased from a size six to a size eight. If the tumour hadn't been removed, the muscles in her heart could have started to grow, restricting blood flow and increasing the risk of a stroke.
