A US woman with advanced breast cancer is healthy again after taking part in an experimental treatment which uses her body’s own immune system to wipe out tumours.

The Florida woman had advanced breast cancer which had stopped responding to chemotherapy and other treatments.

Researchers took a small sample of Ms Perkins’ tumor and studied the DNA mutations in it. They extracted immune cells from the tumor and grew billions of them, finding those most effective to kill her cancer.

Professor Boyle said several immunotherapy trials for triple negative breast cancer treatment will be starting soon in Australia.
