Dna Test May Help Some Breast Cancer Patients Skip Chemotherapy

A new international study suggests that many people with early breast cancer might be able to avoid chemotherapy. Researchers say a DNA-based test could help doctors decide who really needs the treatment and who can safely skip it. The test looks at genetic changes linked to how the cancer may behave. In the trial, the results were used to guide treatment choices, aiming to reduce unnecessary side effects for patients who are less likely to benefit from chemotherapy. If confirmed in further research and used widely, this approach could change care for millions of patients by making treatment more personal and targeted.
