Family and friends are now rallying to raise $150,000 for their brother and colleague to have the growths removed by a top surgeon in Sydney.
They have set up Trade Me auctions and a fundraising page on Facebook, as well as a page on the Givealittle website, which can be found here.
Brett Rattey said: "It's quite a lot of money, but when it's somebody's life hanging in the balance, money is really not important - it's just trying to find a way of getting it."
He said his older brother - who he also called his best friend - was no longer able to work and was keeping positive about the situation.
"As you can imagine, you're obviously shocked when you're told something like this and a million thoughts go through your mind. He's handling it the best that he can. It's a bit rough, but he's a strong person."
Starship paediatric oncologist Dr Scott Macfarlane said that although it was somewhat rare to have a second cancer after surviving the disease as a child, it was still possible. "Unfortunately it is well described and there are some parts of the treatment for childhood cancer that predispose to getting a cancer in adulthood."
