In the ongoing effort to match cancer therapies to the patients most likely to benefit from them, two diagnostic companies have deepened a collaboration aimed at making genetic monitoring of advanced breast cancer faster and more accessible. Biodesix and Bio-Rad Laboratories are joining forces to bring a blood-based test for ESR1 mutations through clinical validation and into accredited laboratories, where it could guide treatment decisions for women with hormone-receptor positive breast cancer. The partnership reflects a broader conviction in modern oncology: that understanding how a tumor ch
