text: A teenager with a deadly brain tumour must raise $80,000 by Tuesday night in order to pay for his life-saving surgery. Jackson Byrnes from  Northern New South Wales was told by doctors that he had a stage four brain tumour that was too deep and aggressive to be safely operated on. The 18-year-old and his family then took matters into their own hands and found the only Australian neurosurgeon to perform the risky operation. After seven days of desperate campaigning through Facebook and the crowd funding page GoFundMe, the Casino teenager is over halfway to his goal with $47,000 being raised. A teenager with a deadly brain tumour must raise $80,000 by Tuesday night in order to pay for his surgery . After a week of campaigning online, the Casino teenager is over halfway to his goal with two days to go . According to the Gold Coast Bulletin, Mr Byrnes' girlfriend, Jahnae Jackson, noticed he had developed a limp a mere three weeks ago and prompted him to visit a doctor who requested an MRI. He was rushed to the Gold Coast for a biopsy which found a stage four tumour buried deep in the teenager's brain. Mr Byrnes was told they would not operate due to how deep the cancer was, but instead suggested chemotherapy and radiation treatment. Knowing that this was not enough, Mr Byrnes and his family searched for a specialist who would perform the dangerous procedure. They found neurosurgeon Charlie Teo who would operate on Wednesday as long as he received an upfront payment of $80,000 by Tuesday evening. The family then turned to social media and crowd sourcing in a desperate plea for donations. 'Most boys his age begin their journey into adulthood with hopes , dreams and anticipation of what lies ahead and excitement of the endless opportunities of what life will bring them,' Mr Byrne's fundraising page on GoFundMe reads.
