flag Multi-cancer blood tests fail to reduce deaths, miss cancers, and cause false alarms, experts warn.

flag Multi-cancer blood tests touted as early detection breakthroughs have underperformed in real-world trials, missing many cancers and causing false reassurance, according to recent studies. flag Unlike proven screenings such as mammograms and colonoscopies, they lack evidence of reducing cancer deaths and generate false alarms, leading to anxiety and unnecessary medical follow-ups. flag A negative result does not rule out cancer, risking delayed care. flag Experts caution against relying on these expensive, unproven tests for healthy individuals, urging people to seek medical attention for persistent symptoms regardless of test results. flag True progress depends on proven strategies, timely diagnosis, and cautious adoption of new tools.
