Millions of breast cancer patients could safely avoid chemotherapy, study suggests

• A DNA test can identify breast cancer patients who can safely avoid chemotherapy without compromising survival outcomes, potentially sparing millions from unnecessary treatment toxicity.
• The test helps stratify risk in patient cohorts currently receiving adjuvant chemotherapy, allowing clinicians to personalise treatment decisions and reduce overtreatment.
• Implementation of this screening tool could significantly reduce treatment-related morbidity whilst maintaining disease control, with major implications for treatment protocols and patient quality of life.

A new DNA test could help screen whether patients require the treatment or not, according to a new international trial.
