The television personality - who has children Zeph, 10, and twins Zena and Xanthe, six, with husband Gerard Cunningham - found a lump in her breast last year which proved to be a benign cluster of cysts, but she had to have another mammogram this year and though that didn't return anything unusual, doctors found a shadow at her follow-up appointment.
Speaking of the first signs, Julia said: 'About a year ago I noticed a lump in my breast. I was away on a work trip and then I came back and we went into lockdown.
'I admit I was a little bit sloppy. It took me a month until I spoke to my GP, who I've known since I was 18.

'Fast-forward a year I still had a lump, and I had something called micro cysts.

Emma Barnett went on to ask how Julia went about how she and her husband Gerard shared her diagnosis with their two children.
'We waited to tell the children because they were about to start school, we wanted to get them in a steady place,' she said.
'It was the hardest conversation that I've ever had to have in my life. I really had to steel myself to be strong but show that you're vulnerable as well.
'One of my little girls said: "Can I still hug you mummy?" and I said "of course you can, I'll need your hugs more than ever".'
The Countryfile presenter admitted her brain 'started to explode' when she was given the devastating diagnosis and she's now preparing to undergo a mastectomy to remove her left breast next month, while surgeons will also remove tissue from her lymph nodes to establish whether the cancer has spread.
She said: 'My surgery is booked for October, obviously it's a huge thing for women. To lose a breast is
