Genomic assays are revolutionizing decision-making in early-stage breast cancer by focusing on the tumor's intrinsic biology rather than solely on traditional clinicopathologic factors. These molecular tests, such as the 80-gene molecular subtyping and 70-gene risk-of-recurrence tests, identify patients who will benefit from adjuvant chemotherapy. Notably, studies like MINDACT and FLEX provide evidence for personalizing treatment plans based on genomic risk profiles, helping to spare low-risk patients from unnecessary chemotherapy while enhancing surgical decision-making.
