What happened: A new international study suggests a DNA test can identify breast cancer patients who do not need chemotherapy. The test screens tumour genetics to guide treatment decisions.
Why it matters:
- Could reduce unnecessary chemotherapy and its side effects for many patients.
- Helps doctors personalise treatment, improving patient quality of life and resource use.
MNN Take: This DNA test offers a more precise way to determine chemotherapy need, potentially changing breast cancer care by avoiding overtreatment.
