Four years ago he had a benign tumour removed but it is believed to have recently resurfaced and medical professionals found some cancerous cells.
In a statement issued to the NME, he confirmed that the reports were true.
“This was going to come out at some point and it’s probably best it’s out in the open now,” he said. “I have been monitored constantly since the first time I had the tumour removed. There was always a chance that it could return and it is unfortunate but it is something I am prepared to get through when the time is right, some point next year.
“The medical staff have been absolutely amazing and I know I am in the best of hands. Nothing will ever stop me from doing the job I love so much, nothing will ever stop me from making music. People shouldn’t worry about me, the prognosis is good and there are so many people in far more serious situations.”
He added: “I just hope this in some way helps raise awareness for those people and encourages people to be tested and treated as early as possible. I am one of the lucky ones!”
The diagnosis comes in the middle of a promotional tour for Newman who recently featured on the Calvin Harris track ‘Ole’.
It was Track Of The Day on Radio 1 earlier in the week and there will be a video released for the song on Friday.
