The Family Court has heard the appeal of the parents of a six-year-old Perth cancer boy who have accepted the court order for continuing chemotherapy but have rejected the ruling for radiotherapy.

According to news.com.au, the doctors have already said that it is difficult for Oshin Kiszko, the cancer fighter, to survive if he does not get radiation treatment. In April, the story grabbed the headlines when the media revealed the parents of the boy were not ready for the advanced treatment of his malignant tumour. His parents were previously against both chemo treatment as well as radiation therapy, but they have agreed for the former treatment option after the court’s order in March.

The boy has already undergone two rounds of chemotherapy. The Perth cancer boy was diagnosed with the tumour in December but his parents, Angela Kiszko and Adrian Strachan, were against his treatment as it had life-long side effects. Unlike other cases, the Family Court has permitted this case to be reported on certain conditions. The court, headed by Chief Judge Stephen Thackray, has now shifted focus on whether the boy should be given radiotherapy.

The court on Monday heard a doctor from Princess Margaret Hospital who specified the chances of the boy’s survival with or without radiation the treatment. Perth Now reported about the doctor who told the court that he was not satisfied with the chemotherapy rounds that the boy had undergone. Hence, he said he would recommend immediate radiotherapy that would give the boy at least a “40 percent chance of survival.”

Andrew Skerritt, the lawyer representing the parents’ case, said that his clients were ready to continue with more chemotherapy treatment as it has shown some improvement in their son’s health. But they still refused to go for radiotherapy because of its long-term side effects, which also included declined cognitive ability.

Justice Thackray called the case an “exceedingly difficult matter” and “a matter of life and death.” The reports indicated that the court’s verdict will be given at the end of this week. If the judgement goes against the parents, the doctors will start radiation treatment starting Monday, otherwise, the boy will go for more rounds of chemotherapy.
