Doctors have successfully removed more than 90 per cent of a small child’s brain tumour after his parents were told it was inoperable and he was flown from Mexico to Spain for an emergency procedure.

The adorable two-year-old named Oliver Romero is recovering in a paediatric Intensive Care Unit at the Sant Joan de Deu (SDJ) Hospital after undergoing a 10-hour surgery that saw most of his brain tumour removed.

The operation was performed in the city of Barcelona in Spain on Friday, 28th October, according to local media reports.

This was after the toddler was flown from the city of Cancun in Mexico, where he lived with his parents, to the city of Barcelona in a medivac plane.

Oliver’s parents were initially told that their child’s aggressive brain tumour was inoperable after he was treated by doctors in Cancun, according to reports.

A sudden change in fortune reportedly resulted in an anonymous businessman offering to pay for the toddler to be flown to the respected children’s hospital in Barcelona where he was operated on by two specialised brain surgeons after SDJ Hospital officials reached out to the family.

Oliver’s dad told local media: “Everything has gone well, now he is recovering; his mother is with him.

“In a couple of hours, when the effects of anaesthesia wear off, he will be able to go up to his room”.

Oliver was operated on for hydrocephalus, or the build up of fluids in brain cavities which increases intracranial pressure, according to reports.

A “molecular study” of the small child’s tumour will begin so that Oliver can be given the correct oncological treatment, according to a statement Newsflash obtained from the hospital.
