A new study (NHS-Galleri trial) tested whether a simple blood test could catch more cancers early.
Bottom line: Stage 3 and 4 cancers (together) were not lowered by this study, so this test is NOT ready for prime time yet! A small silver lining is that when looking at stage 4 cancers alone, there was a 14% reduction, which MIGHT be promising.
What does this mean?
- We know that the key to effective screening tests is to find cancers at an early rather than late stage.
- This study tells us that more work is needed before blood tests become routine screening.
