Neon Roberts must have surgery to remove brain tumour, High Court rules We don't have the luxury of time ... and in the circumstances the surgery must be done as soon as possible. The court was earlier told that Mrs Roberts did not "consent" to the treatment because she felt the medical advice was flawed and a second opinion was needed. Mrs Roberts, a former DJ, "thought long and hard" about the decision to grant permission for Neon to have the surgery but changed her mind at the last minute, the High Court was told. After initially consenting to the surgery, Mrs Roberts decided at the eleventh hour she was "not able" to allow her son to have the operation. Doctors said the boy needed further surgery to remove the growth before undergoing chemotherapy and radiotherapy treatments. Preparations are now under way by doctors from a hospital, which cannot be named for legal reasons, who are treating Neon. His parents will be at the hospital tomorrow. A team of experts including oncologists, neurosurgeons, radiologists and pathologists had all agreed that surgery was needed, the judge said. Mrs Roberts, originally from Auckland, New Zealand and her estranged husband Ben, 34, were last week told that doctors had uncovered a mass in the area of the brain in which the tumour had been removed. The "vibrant" young boy underwent MRI scans which uncovered the centimetre mass in an area where the previous brain tumour was removed. The court was told that the growth is more than 1.5cm square in size, meaning that Neon was now in a "high risk category." Neon's surgeon, a leading paediatric oncologist who can only be known as Doctor A, had told the court without surgery Neon would almost certainly die. "It is highly, highly likely he will die and he will die over a short period of time," he said. The court was told that Mr Roberts, an IT consultant from Knightsbridge, west London, was supporting medical experts in their arguments for surgery. He was not in court for the judgment. Earlier her barrister Robin Tolson, QC, told the court: "This for the mother, is a very serious issue. The present position [is] she does not feel able to consent to surgery. The court heard she is still attempting to find "other" expert evidence which was different from the UK "gold standard." The court heard there was a risk Neon could become mute. Mrs Roberts also today dismissed her legal team and was poised to appoint Imran Khan, a well known human rights lawyer who has represented defendants in major terrorist trials as well as family of Stephen Lawrence. Mrs Roberts, who provoked a nationwide hunt when she went missing with her son earlier this month, had previously said she would consent to the full treatment if the cancer, called medulloblastoma, returned. The mother who left her home in Devon and fled to Brighton, East Sussex, has insisted she is not a "bonkers mother" after she disappeared to prevent Neon from receiving radiotherapy. Mrs Roberts declined to comment outside court. Her husband and his relatives also did not comment. A decision on whether Neon should receive both radiotherapy and chemotherapy will occur on Thursday.
