The test returned an elevated result and he then underwent an MRI and biopsy.

“Prostate cancer, if you get it early, is very, very treatable; in fact, about 97 per cent successful,” Joyce said.

“So I’m very blessed and lucky to discover this early.

“I’ll have the operation on Monday and I will then have a couple of days in hospital and will recuperate after that.”

The Nationals MP is positive about his recovery.

He retained his federal seat of New England on Saturday night at the federal election, and said he will continue on in the role.

“If I thought it was very serious, of course I’d resign, but my doctors or surgeons say, ‘You’re very lucky you’ve got it early’.”

Joyce urged other men to get tested, saying he had no symptoms but thankfully had a “very diligent general practitioner”.

“She insisted on me getting a PSA and wasn’t I lucky that she did that, because otherwise we’d be having a different conversation in a couple of years’ time.”

The New England electorate is located in NSW, starting at the Queensland border and encompassing towns including Armidale, Glen Innes, Inverell, and Tamworth.
