The 12 brain tumour symptoms to be aware of as Davina McCall undergoes surgery

Davina McCall is undergoing surgery today after revealing she has a 14mm benign brain tumour and has asked fans to “pray for her” ahead of the op.

The 57-year-old TV presenter discovered the rare brain tumour during a health scan. She said the chances of having the rare colloid cyst were "three in a million". She discovered the cyst a few months ago, after being offered a health scan in return for giving a menopause talk.

She admitted: "I slightly put my head in the sand for a while, and then I saw quite a few neurosurgeons, I got lots of opinions. I realised that I have to get it taken out. I'm having it removed."

She then added: "Say a prayer for me. I'm in good spirits."

In a video posted on Instagram on Friday morning, she explained what surgery she will be having. She said: “It will be removed via a craniotomy – they go through the top of my head here, and through the two halves of my brain to the middle, get the cyst, empty it, take it out, and Bob’s your uncle.”

Her partner Michael appeared on the video too and said: “Just letting people know that I will have my eye on her throughout this procedure!” And then he joked: “In fact I offered to do the operation, just to make sure it was done properly! They wouldn’t let me. She’s in very good hands.”

Davina then told fans that she will face a few weeks recovery including a nine-day hospital stay, but that Michael will provide an update on her health.
