Breakthrough could lead to ‘more effective and targeted’ breast cancer treatment

As part of the treatment, T-cells – blood cells that protect the body from infection and disease – are genetically modified in a lab to make them better at killing cancer and returned to the blood.

Researchers tested out the targeted immunotherapy on mice.

A treatment that targets cells that help tumours survive, rather than directly attacking cancer itself, could help prevent the growth and spread of breast cancer, according to a study.

Using immunotherapy to treat breast cancer “has had limited success”, researchers said, but their breakthrough could help “develop a more effective and targeted treatment” for the disease.
