An experimental cancer treatment based on rainforest berries has been successfully shown to destroy tumours in a matter of days.

A drug based on the fruit of the Australian blushwood tree is currently undergoing trials in Queensland.

Denise Powell, a cancer patient who is part of the trial, said the treatment had a radical effect on a tumour in her armpit.

She told Channel 7: “My cancer surgeon said, ‘I can take that one out, if you get any more you might lose an arm.”

The chemical inside the berries is called EBC-46 and has already been shown to shrink tumours in animals.

But Denise was shocked to see how profound an effect it had when injected directly into the growth under her arm.

“In less than 20 minutes the tumour had gone purple then black,” she added..

“Then within a couple of days the tumour just kind of shrivelled up and died."

EBC-46 works by triggering the body's immune response so white blood cells begin to destroy the tumour.

It is believed the chemical could treat head, neck, breast and prostate cancers, as well as other types.

However, it will not be able to tackle metastatic cancers which have spread around the body.
