'You may get your wish, I may be dead': Sandilands to undergo brain surgery

The KIIS FM breakfast show DJ told co-host Jackie 'O' Henderson that he was facing a grim diagnosis after missing the January 31 show to seek medical treatment for painful headaches.

"It's not a blockage. Imagine your blood vessel is the garden hose and the garden hose is weak and it blisters out like a big bubble, you know, like a puncture in it, like a bike tyre with a big bubble," Mr Sandliands said on February 3.

"It's expanded and if it bursts, [I'm] either a vegetable in the wheelchair or dead," he said.

The 53-year-old said his medical team advised that the aneurysm required "immediate attention" and that he would undergo surgery as soon as possible.

"If you just tuned in to us after all these years, lap it up. And if you're in Melbourne, you're coming to the party too late. You may get your wish. I may be dead," he said to listeners.

The radio host, and father to a 2-year-old boy, plans to miss between two and eight weeks of broadcasting to recover.

"They can either do keyhole surgery, or they'll have to cut away parts of my skull and open up my head to fix it," he said about the surgery.

"The facts are a life of cocaine abuse and partying are not the way to go," he said.
