The Great British Bake Off host Sue Perkins says she has lived with a non-life-threatening brain tumour for eight years.
Sue, 44, revealed to Good Housekeeping magazine that she has a non-cancerous tumour in her pituitary gland, a pea-szied gland on the udnerside of the brain, which is vital for producing and regulating hormones throughout the body.
She discovered the tumour while having test for another BBC show, Supersizers.
She told the magazine: "I'm lucky that it's benign so it's not in itself a worrying thing. Sometimes it's big and makes me mad, and sometimes it's small and is in the background...
"Sometimes it screws up my hormones. I have various tests now to make sure the side effects aren't too onerous."
Sue presents the hit BBC baking show with her comedy partner Mel Giedroyc and is in a relationship with TV producer and journalist Anna Richardson.
One unfortunate by-product of the prolactinoma is that it affects the secretion of reproductive hormones, which means she cannot have children.
Sue said: "I don't know if I would have gone on to have children. But as soon as someone says you can't have something, you want it more than anything."
Sue tweeted her thanks to online well-wishers on Monday night:
Ta for sweet tweets about my prolactinoma. It's benign & non-symptomatic. All fine, Let's focus on those less fortunate in the world. X
