University of NSW develops "dialysis for cancer" system

A NEW system that dramatically lowers the cost of cancer treatment has been developed by a team at the University of New South Wales.

The biochip filters the blood to identify and then remove cancer cells, in a system the team calls "dialysis for cancer".

Initially the NSW University team was looking for a cheaper and less painful way to diagnose cancer.

At the moment, the way a tumour is identified in a body is with a scan and then a biopsy.

But solid cancers, which make up about 99 per cent of human cancers, also shed what are called circulating tumour cells into the bloodstream, which is how the cancer metastasizes, or spreads through the body.

Dr Majid Warkiani and his team at NSW University created a biochip that is able to separate the cancerous cells, which are larger and more flexible than healthy cells, and identify them.
