'The worst part is when your own child comes up to you and says: "am I going to die, mum? ",' Christina's mother, Nayree Lagogiannis, told Daily Mail Australia. 'She had already Googled everything, let me tell you, but I said "I will promise you that I will do everything in my power to help you get better and I will not let you die".' Mrs Lagogiannis watched as her daughter took on a full knee and femur replacement, further surgery on her knee due to infection, a biopsy and then keyhole surgery on her right lung followed by three more open surgeries on her lungs to remove a number of lesions.

She's not going to have any more of that poison running through her veins. 'Each time they go in they have to take out a piece of her lung, and then there's only so much of the lung they can remove and that's when they will put her on palliative care. I'm not going to let that be the last alternative.

There is so much funding for things like breast cancer, but the smaller cancers and less common things that have also been around for many, many years - the treatment hasn't changed for more than 30 years.' It was her promise to her daughter that led Mrs Lagogiannis to research treatment options available in Germany. She came across the Medical Centre in Cologne which offers hypothermia and dendritic cell vaccinations, both of which are not available in Australia, and promises a '95 per cent chance that she would either go into full remission or 50 per cent remission,' Mrs Lagogiannis said.
