Davina McCall has said she is to undergo brain surgery, after being diagnosed with a “very rare” tumour. The TV presenter, 57, said the benign brain tumour, known as a colloid cyst, was found after she was offered a health check-up as part of her menopause advocacy work. In a video on Instagram, she said: “I’m posting this. It will be Friday morning, and I’m doing it because a few months ago, I did a menopause talk for a company, and they offered me a health scan in return, which I thought I was going to ace, but it turned out I had a benign brain tumour called a colloid cyst, which is very rare, three in a million."
