Meet the parents who don't want to give their son potentially life-saving treatment.

Angela Kiszko and Adrian Strachan love their six-year-old son Oshin, but they don’t want to give him potentially life saving cancer treatments.

The family made national news last week when a West Australian Family Court enforced Oshin’s access to the radiotherapy and chemotherapy treatments, despite their wishes.

Last night they told their side of the story to 60 Minutes.

“I don’t understand it, and I’ve said that to the oncologist,” Kiszko said. “I said, ‘If I could understand your treatment I’d be for it, but I just, in my head I cannot understand it.”

When asked what she didn't understand, Kiszko continued, "They're treating cancer with a carcinogenic. Or two carcinogenics. It doesn't make sense to me and I find it really difficult to see that that's called a treatment."

Oshin has been diagnosed with medulloblastoma, a fast growing, high grade and invasive malignant tumour located in his brain in December last year.

And while the surgery that followed shortly after went well, it was in the months that followed that all of the problems began.

While waiting to know the outcome of the surgery, Kiszko and Strachan began treating their son with herbal therapies and looking into alternative treatments overseas.

By the time doctors found the cancer remained and recommended chemotherapy and radiotherapy to improve Oshin's chances at surviving, both parents were completely disillusioned.

"I read what he needed to go through, I read the care plan, all the side effects and I literally just wanted to vomit. And I felt I would not put myself through this, how can I possibly put my son through this?" Kiszko said.

But Australian Medical Association President Professor Brian Owler told 60 Minutes that one is just as important as the other. "If you just do the surgery, we know that the child is unlikely to survive. With radiotherapy and chemotherapy if you achieve a good surgical resection first up, then the survival rates can be well over 80 per cent."

After unsuccessful mediations with the family, doctors made the decision to seek court enforcement.

"It is the last resort because you want to work with the family, but in a situation where it's life or death for that child it's very clear what that decision is going to be."

Oshin's treatment began last week.
