Good article on Aysha King here: https://www.independent.co.uk/voices/comment/ashya-king-this-story-isn-t-quite-what-it-seems-9716486.html
Essentially, the NHS removed his brain tumour and planned urgent life saving chemo and radiotherapy. They predicted he had a very good chance of survival but urgency of treatment was important.
His parents preferred a different type of radiotherapy, which can be superior to standard radiotherapy in terms of reduced side effects (and the NHS were sponsoring patient to receive it abroad where this applied) but in his particular case due to the location of his tumour, wouldn't have made much difference. However, Southampton hospital offered to explore every possibility of seeking this opportunity abroad with Aysha's parents.
However, his parents took matters into their own hands when they didn't return with him from planned home leave from the ward. Medical staff caring for him would have had no idea of their intentions and serious, immediate concerns for his wellbeing not to mention concerns that they might not be seeking treatment for his cancer, at all. Understandably, the police were involved as this is very obviously an immediate safeguarding matter.
From this point, Aysha was not taken to a hospital until after his parents arrest, by authorities. He was then admitted to high dependency (in Spain), suggesting he was a significantly unwell child at this time, who his parents until that point had been keeping in a hotel room. It's not clear what if any plans they had in place to seek the treatment they wanted in Spain.
Ultimately, he received their preferred treatment in Prague, and survived. Because the treatment is not more effective than standard radiotherapy, it's safe to surmise he also would have survived had he received the recommended NHS treatment. Noone can comment on the possible side effects, other than apparently the evidence from previous similar cases of either treatment not making much difference with his type and location of tumour.
I've no doubt his parents wanted to do what was best but their behaviour was disorganised and endangered him. They significantly delayed his urgent cancer treatment and withdrew him from medical supervision at a time when he was significantly unwell. Their actions could easily have harmed him and the police response was completely appropriate and did in fact result in him being taken to a safe hospital setting and proceeding to receive appropriate treatment.
Bee in my bonnet about this somehow being warped by bad press and rumour into the NHS and police being baddies that wanted a little boy to die(!)
However, it is a really good example of how media reporting and public discourse can become totally warped and inaccurate on medical topics. Because outrage is what sells and spreads.
