"You do have a tumour. It's a big one."
Neurosurgeon Charlie Teo is confirming the huge white mass on your brain scan cannot be anything else. After having it surgically removed you discover it is malignant - the most aggressive type of brain cancer, a grade four.
What are the chances then, that your scientist father is researching that exact type of tumour, and works with people who are trialling a vaccine therapy that could keep you alive?
Improbable, but not impossible?
That is the story of David Murrell, a 35-year-old photographer based in Sydney, who was diagnosed with glioblastoma multiforme (GBM) three years ago.
His father Wayne Murrell is a scientist in a neurosurgical research lab in Norway.
"I had this stunned numbness, because I knew damn well how bad tumours could be," Dr Murrell said.
"I asked my boss Iver Langmoen about it. He's a professor of neurosurgery but he's also the leader of our lab, which is part of the Oslo University Hospital.
"He said: 'Do what you think, find out what you can, organise it, call it work'. Which was very good of him."
David's outlook was bleak. In general, a grade-four primary brain tumour has an average survival of 14 months.
"I spent a couple a days meditating and just getting it out of my head that the life expectancy is months," David said.
"I said: 'That piece of information is completely useless to me. I got to get that out of my head because it serves no role other than to instil fear and that's a useless emotion'."
Dr Murrell moved to Norway in 2007, and gained a position as a senior scientist at the Vilhelm Magnus Laboratory for Neurosurgical Research.
He had previously completed his PhD at the age of 40 at Brisbane's Griffith University.
"The aim of our lab is to make therapies. And we have two main goals: one is to try and cure glioblastoma; the other is to do brain repair for people with damaged brains or with Alzheimer's, Parkinson's and so on," he explained.
"My boss always wanted me to get more interested in glioblastoma. Now I am, of course."
'Death was the first thing that crossed my mind,' says brother
Two years before David's diagnosis, the Oslo University Hospital began recruiting patients for a vaccine therapy trial for glioblastoma. This was a collaborative work involving the Vilhelm Magnus Laboratory.
Then in March 2011, while on a work trip to Indonesia, David went to a Jakarta hospital with a bad case of dengue fever.
"I'd [previously] had a couple of dizzy spells. I thought: 'Oh I should get a CT scan and check everything's OK'," he said.
A tumour the size of an orange was revealed on the CT scan and subsequent MRI.
"It was quite shocking to think that something that large was inside someone's head and they were walking around and operating all this time," David's friend Mike Corte said.
His brother Hugo admits: "Death was the first thing to be honest that crossed my mind".
"I thought, we'll be counting down the time left with him straight away," he added.
Father realised he could help his son
Dr Murrell says he was devastated for a day or two, but then he realised he could do something to help his son.
"I'm a scientist, you know, I don't believe in coincidence. But rather than sit as a normal family would have to and just wait for the worst to happen I decided I would do something," he said.
Dr Murrell's boss and the head of the Cellular Therapy Department at the Oslo University Hospital, Gunnar Kvalheim, agreed that David should be treated as a compassionate case alongside the vaccine therapy trial.
While he is not formally included in the phase one/phase two study, which is restricted to Norwegian patients, his vaccine is identical to the one being used in the study.
The trial is testing a dendritic cell vaccine, which uses stem cells from a patient's tumour, and monocytes from their blood, to harness the patient's own immune system to seek out and kill any tumour cells that may be left over after surgery.

In order to do this, Dr Murrell had to first contact David's surgeon, Dr Brindha Shivalingam at the RPA Hospital in Sydney.
She agreed that Dr Murrell could collect some of the live tumour tissue that she would remove from David's brain, in order to grow and isolate the cancer stem cells himself.
Dr Murrell then had to transport the live tumour tissue back to Norway in tiny flasks in his jacket breast pockets, because they had to remain at body temperature to stay alive.
Making the vaccine takes several weeks, so during that time David underwent radiotherapy and chemotherapy to slow down any tumour regrowth.
David documented 'the fight of my life'
Now, three years after diagnosis, David is alive and well, and regular MRI scans have shown no sign of a tumour. He returns to Norway every two months for ongoing vaccinations.
During that hospital trip in Jakarta, David decided to turn the camera on himself.
"I picked up my phone and just started filming. And I decided right there on the spot to start documenting my journey," he said.
"The purpose of which was going to be to help other people with life's big challenges. 'Cause I knew it was going to be the fight of my life."
While the vaccine therapy trial is showing promising results, it is too early in the trial phase to draw any definitive conclusions.
"It's early days in cancer vaccines," Dr Kvalheiml said.
It's starting to hit us all I think, including Dave, that Dave actually might be going to live.

"We do see very interesting results coming up all over the world, but I have to remind people that it still takes some time until we know which patients might benefit and in which way they're going to be treated.
"Here in Oslo we are one centre among others that are trying to do our best to develop cancer vaccine for our patients."
For now, in David's case at least, the vaccine seems to be working.
"It's starting to hit us all I think, including Dave, that Dave actually might be going to live and he needs a life back," his mother Heather said.
David adds: "I do feel at the moment like I'm in a bit of limbo".
"I'm sort of being forced by the universe to exercise some patience and wait. Which is hard when you're an impatient person and you've just been through what I've been through.
"I'm like: I'm ready, I'm ready, I'm ready."
