An Aussie mum says she will even sell her kidneys to raise the money needed to get to China so Australian neurosurgeon Charlie Teo can operate on her son.

“I am prepared to do anything to make this happen for Riley … the kids laughed at me when I wanted to look into selling my kidneys … that is just the lengths I will go to,” Beck Bierton told news.com.au.

“Professor Teo is the only person in the world willing to try to save my son’s life. As a parent, I cannot accept watching this tumour continue to grow when there is someone willing and able to remove it.”

Ms Bierton said she first saw Prof Teo on the news in a story about him performing surgeries on tumours like Riley’s.

“For the first time since Riley’s diagnosis I had hope like never before. I told my family, ‘Charlie will be the one who saves my boy’.

“Although I was shut down on that idea from the hospital, Charlie has never left my heart and hopes.”

Riley has lived under the weight of this life-threatening brain tumour for 20 years.

As the tumour has progressed, it has started to affect him physically. He has lost vision in his left eye and is now losing strength and muscle function.

Because of the tumour’s location in the brain stem, this surgery is extremely complex. The only neurosurgeon willing and able to attempt it is Professor Teo.

Restrictions placed on his licence in Australia mean Riley would need to travel to China for the surgery at a cost of $80,000.

Time is running out and Riley and his mum need to raise the funds by March 1.

Diagnosed with what doctors believed was an inoperable diffuse brain stem tumour, his mum was told to prepare for the worst.

“We were given six months with our beautiful little boy,” Ms Bierton said.

“He underwent chemotherapy, which thankfully slowed the tumour’s growth, but we lived for years under the shadow of a diagnosis that said there was no hope. We were told nothing more could be done.”

But six months passed. Then a year. Then 10. Then 15.

At 17, the tumour began progressing again and Riley endured another course of chemotherapy.

“That’s when something became very clear. This was never the aggressive, malignant tumour we were told it was,” Beck said.

“Today, my son is 21 years old. He is here. He is alive. He is strong. And we now know the original diagnosis was likely wrong. The tumour is progressing again, and this time we refused to accept the same answer.”

Dr Teo believes the tumour is a benign JPA (juvenile pilocytic astrocytoma), a type of tumour that can potentially be removed completely.

“He has been incredibly honest about the risks,” Beck said.

Just wanting to live his life tumour-free, Riley is hoping to raise the funds needed to get to China but the clock is ticking. Picture: Supplied
“Brain stem surgery is delicate and complex. But for the first time in 20 years, there is a real chance, not to slow it, not to manage it, but to remove it. And we cannot ignore that chance.”

The $80,000 is need to cover hospital and surgical fees, specialist medical team costs. flights and accommodation overseas.

Riley told news.com.au that not a day goes by where he doesn’t think about the tumour and dying.

“Not many people would be able to tell I had a brain tumour as I never allowed it to limit me and hold me back,” he said.

“Mum shared a story with me of when I first went on chemotherapy at 20 months. It was only weeks into it when she was finding me constantly hospitalised on the verge of death with all the side effects of the chemo. The doctors told my mum to basically wrap me in bubble wrap as I had no immunity.

“I was in my pram. It has been raining and my sister and brother were running in the rain, sliding in mud having the times of their lives. I was latched in my pram pulling at my straps crying to let me out so I could play with my siblings.

“In a split second my mum made a life-altering choice to unstrap me out of the pram and let me go play in the mud with my siblings.

“I believe this split decision has had a crucial impact on my life. From that moment on I was going to live and nothing was going to stop me.”

Prof Teo – who is being built a state-of-the-art teaching facility in Wuzhishan – has told news.com.au he believed Riley’s tumour “is and always was benign, surgically resectable and curable, if it was done when he was a baby”.

Dr Teo formally requested that the Medical Council of NSW lift the conditions imposed on his registration. These restrictions, stemming from findings by the Health Care Complaints Commission regarding two past cases, mandate that he obtain written support from an approved neurosurgeon for specific complex brain surgeries.

ince these conditions were imposed, Dr Teo has performed 236 surgeries abroad under supervision, reporting excellent results for 202 patients and good outcomes for 28.

The Medical Council of NSW maintains it cannot comment on ongoing matters, only publishing decisions on the national Register of Practitioners
