health ๐ฌ Blood test spots breast cancer way earlier than scans
A personalized blood test named Pathlight detected circulating tumor DNA up to 13.8 months before metastatic breast cancer was clinically visible. This study followed 136 patients across various cancer subtypes at Lund University. Data collected over six years, including nearly 1,497 blood samples, showed early signs in some cases up to four years before visible symptoms. Persistent tumor DNA strongly predicted later recurrence and poorer survival outcomes for these patients. Researchers still need clinical trials to confirm that acting on this early blood test actually improves patient results. ๐ฌ
