About 70% of women with the most common form of early stage breast cancer can be spared the “agony of chemotherapy”, researchers say.
It follows trials of a genetic test that analyses the danger of a tumour.

As a matter of urgency, research is needed to find similar hormone treatment for patients with cancer at other sites, including head and neck, and if they will have similar benefits.
