Alan Jones called a press conference today to reveal he has prostate cancer.

The 67-year-old 2GB broadcaster said he wanted to avoid rumours.

He said he would be undergoing surgery in a couple of weeks time after a biopsy and that he had been told the prospects of a full recovery were good.

"We don't do dying around here. We just do living," he said.

He would be off air for several weeks while recovering from the operation, he told media gathered at the Macquarie Radio studios in Sydney.

Jones said he was diagnosed in May after doctors examined 20 samples, and his cancer had been described as in the mid-range in terms of seriousness.

The surgery would be carried out at Sydney's St Vincent's Hospital in two weeks, and Jones said he intended to be on air until the eve of the operation.

He would return to broadcasting after the operation, he said.

"Of course I will be returning to air, I've got to make a quid,'' Jones said.

He said he was maintaining a positive outlook and was confident he had the best medical team behind him.

He said others were suffering infinitely more than he was and it would be selfish of him not to be positive about his prospects.

Only last week he gave a eulogy at Jane McGrath's funeral after her death from breast cancer.

"You've just got to take things as they come," he said.

Mr Jones said he hadn't been sick in his life but this year had been a bad one.

He said he would be undergo surgery in a few weeks time and that he had been told the prospects of a full recovery were good.

He planned to return to work tomorrow, he said.

"My advice to anybody ... you've just gotta ... you keep going, doesn't matter in what direction.

"People face difficulties and adversities every day and I'm of the view that youve got to confront them and not yield to them and get on with life.

"There are good things out there to look forward to and that the point and this is a bit of an interruption and we don't tolerate interruptions."

The former teacher and Wallaby coach is one of Australia's highest-paid media stars who has driven 2GB's ratings to the top with his early morning show.
