John Newman has revealed he is struggling from anxiety as he is still living with a brain tumour.

The 27-year-old singer was told he had developed a second brain tumour in 2016 after having previously beaten the growth once before, and although an operation is needed to completely remove it, he has admitted he's still yet to undergo the surgery.

John - who has recently returned to the music scene after undergoing treatment to keep the tumour at bay - said: ''I still have it in my head. I never had the operation. I presumed I was going in. I could feel it. I was like, 'Right, it's time. I need to take a break'.

''I went in and the incredible woman that I speak to said, 'We've got good news and bad news, in a way. The good news is we don't have to do an operation now'.

''I was like, 'Right, what's the bad news?' She said, 'Well it hasn't grown at all but it's just sat there and now you've got to live with the anxiety of knowing it's still there'.''

The 'Love Me Again' hitmaker knows he will need to go under the knife eventually, and although he says he ''struggles'' with his anxiety, he understands that other people need to be operated on first.

He added: ''One hundred per cent, 110 per cent, it will be operated on. It's got to be operated on. It's got to come out. I've got to go through radiotherapy or chemotherapy, just, I don't know when.

''It's just sat there and it's really annoying. I was like, 'Can you not just get it out anyway?' But there's people who need (an op) a lot more than I do, so they should get the time. I'll get the time when I need it.

''I struggle from a lot of anxiety. The rate of growth currently, they don't believe there is cancerous cells in it.''

But John isn't letting his illness affect his music career, which he recently relaunched with new single 'Fire In Me'.

Speaking on the Dan Wootten Interview podcast, he said: ''I've got this thing in my head. It's part of my body and I have other things I need to concentrate on.''
