Story summary

Blood tests that analyze circulating tumor DNA (ctDNA) are transforming the landscape of cancer detection and monitoring. They excel at spotting aggressive cancers, such as pancreatic and liver cancer, at earlier stages. While they hold promise for predicting recurrence through molecular residual disease tests, they cannot replace traditional screenings for precancers and early-stage cancers.
