Opera singer Russell Watson has completed a five-week course of radiotherapy to eradicate a recurrent brain tumour.
The 41-year-old singer said the treatment at Manchester’s Christie Hospital had been ‘no walk in the park’.
His manager Giles Baxendale of Merlin Elite said: “He’s finished his treatment but he doesn’t know whether he is in the clear yet.”
He said regular scans would reveal whether the treatment had been successful.
The singer – known as The Voice – wrote on his website blog: “It’s been no walk in the park; I’ve had my moments under that machine where I just wanted to stop the bloody thing and walk away.”
Mr Baxendale said fears that the singer’s eyesight or voice would be damaged by the radiotherapy appeared to be unrealised.
Watson wrote on his blog: “I’m not out of the woods yet. I dearly wanted to keep the side-effects to a minimum and I’ve been keeping myself fit and healthy as I can, but I’m afraid they’ve caught up with me, and I don’t mind admitting I’ve not been myself.
“I’m just so lucky I’ve had friends, family, and of course my fans to help me through; I really don’t think I could do this without the support I’ve had.
The singer – whose album Outside In entered the top 20 when it was released in December – underwent surgery to remove the brain tumour in October. It was his second operation on the tumour in 12 months.
