Scientists behind the discovery that sufferers of aggressive breast cancer stand a better chance of survival if they have "killer" T-cells near their tumour said the finding was "key" to a better understanding of how to fight the disease.
Professor Peter Johnson,Cancer Research UK chief clinician, explained:
This research highlights the great strides we are making in understanding the complex interplay between cancer and the body's immune system.
These studies are key to informing how we are best able to treat patients in the clinic and to design better drugs that make the best use of the body's own defences.
