Crispy enough to crunch, soft enough to enjoy. A good bake.
Summary
A large-scale clinical trial of the Galleri blood test, which detects cancer DNA fragments in blood, showed promising results with 25,000 participants from the US and Canada. The test identified cancer in nearly 1% of participants, with 62% of positive cases later confirmed to have cancer. The test demonstrated high specificity, correctly ruling out cancer in over 99% of those who tested negative. Researchers believe this technology could fundamentally change cancer screening by enabling earlier detection when treatment success rates are highest.
