WA cancer battle boy dies in mum's arms

Oshin Kiszko, the six-year-old Perth boy at the centre of a court battle over treatment of his brain cancer, has died in his mother's arms.

Oshin was diagnosed with a malignant brain tumour last year, but his parents Angela Kiszko and Adrian Strachan opposed the treatment recommended by doctors due to severe side effects.

In September a judge ruled Oshin should move to palliative care and not be forced to undergo radiotherapy, after a court order in March had forced him to receive chemotherapy.

Oshin died on Wednesday morning.

His mother released a statement to 7 News in Perth saying: "My love Oshin took his last breaths peacefully as I lay cuddling him at 2am this morning.

"Oshin's journey has been extraordinarily traumatising for him and I am grateful he no long needs to suffer through this nightmare."
