John Newman's brain tumor has returned.
A source close to the singer told The Sun news paper:
John's brain tumour is back. He's known about it for a while but has kept it a closely guarded secret, confiding only in those closest to him - his mum, brother and few loyal members of his family.
"Now he's started telling people because it won't be long before he talks time out for treatment.
"Although the tumour, thank god, is benign doctors have found a few cancerous cells on it.
"Fortunately, because the tumour has stayed the same size for a while John's been told that surgery can wait until next year.
"After the operation, he'll need some radio therapy so there's talks of him taking a few months off to get the job done and convalesce."
Having gone through the same thing in 2012 - when John was diagnosed with a smaller tumour - he is said to be "a lot calmer", although, it is "emotionally draining" for him.
He continued saying:
"For a while afterwards patients can feel weak, have fits, find it difficult to walk and encounter speech problems.
"Although he's trying to remain as positive as possible it's a really emotionally draining time for poor John."
