• Implementing multi-cancer blood tests in routine screening could help doctors diagnose cancer at earlier stages, when treatment is more effective and patients are more likely to survive the cancer. • Harvard researchers have simulated the long-term effects of introducing this type of cancer testing in routine screening. • According to their predictions, yearly screenings with a multi-cancer blood test would massively shift cancer detection to earlier stages over the course of 10 years, reducing by 45% the number of late-stage diagnoses, where the cancer has spread and often become resistant to treatment. • “Our analysis shows that multi-cancer blood tests could be a game changer for cancer control,” said Jagpreet Chhatwal, lead author of the study and director of the Institute for Technology Assessment at Massachusetts General Hospital and Harvard Medical School. • “By detecting cancers earlier-before they spread-these tests could potentially improve survival and reduce the personal and economic burden of cancer.” In the U.S., about half of cancer cases are diagnosed at an advanced stage. • Despite the importance of early diagnosis, routine screening is currently recommended for only four types of cancer: breast, cervical, colorectal, and lung cancer.
