Sorry, but Blood Tests Won't Replace Stool Samples or Colonoscopies Yet

Liquid Biopsies Face Setback in Early Detection of Colon Cancer #

Blood tests known as liquid biopsies, designed to detect cancer early, have faced disappointment in their application to colon cancer. Freenome, a privately held company, recently announced lackluster results from a clinical study aimed at early detection of colon cancer in average-risk adults. These results disappointed investors, highlighting the challenges of developing effective blood-based tests for colon cancer, which is the second leading cause of cancer deaths after lung cancer. Despite the setback, the pursuit of improved early detection methods continues in hopes of revolutionizing cancer treatment.
