Two devout evangelical Christians whose 10-year-old son is in intensive care with a brain tumour are in a High Court battle with doctors. Specialists want a judge to allow them to limit the treatment they provide to the youngster, saying the boy cannot recover and should be made as comfortable as possible without further ‘invasive’ procedures. The boy's parents, who are separated, disagree and say doctors should not limit treatment options. They ‘lavish’ the youngster with love, and play gospel music to him. The judge began considering evidence in the family division of a high court on Tuesday. Lawyers representing the boy's parents said life was ‘precarious and uncertain’, and people sometimes made unexpected recoveries. The parents believe there are things that could be done, but that doctors are giving up.
