Davina McCall is to have surgery to remove a brain tumour, she has revealed. The TV presenter posted a video on Instagram to say she had been diagnosed with a rare type of benign tumour called a colloid cyst. A benign tumour is not cancerous, but such cysts tend to grow slowly, according to the Brains Trust charity.

Davina McCall has undergone brain surgery for a non-cancerous tumour, she revealed today. In a video posted on Instagram, the television presenter explained that a private health check – that she expected to “ace” – showed she had a colloid cyst. “It needs to come out because if it grows, it would be bad,” the 57-year-old said.
