Scientists have developed a DNA blood test that predicts how breast cancer patients will respond to treatment.
The test analyses circulating tumour DNA released by cancer cells into the bloodstream.
Low DNA levels before treatment were strongly linked to better treatment responses.
Similar results were seen after just four weeks of therapy.
Researchers studied blood samples from 167 patients with advanced breast cancer.
Patients with low DNA levels had longer periods without cancer progression.
The findings suggest ineffective treatments could be avoided early.
Doctors could switch patients sooner to better therapies or clinical trials.
Researchers say the test could make treatment faster, more personalised and more effective.
