A new blood test detected 87% of early pancreatic cancers—and may spot precancerous changes too

The useful part

Would you take a pancreatic-cancer blood test if it became available before doctors knew exactly how to interpret every positive result? That is why an experimental blood test reported in Nature Medicine is attracting attention. In a large international study, the test detected 87% of stage 1 and stage 2 pancreatic ductal adenocarcinomas while correctly identifying 95% of people without cancer as negative.

How it works

• The underlying research is available in the Nature Medicine study.
• The test looks for several biological signals at once Researchers developed a liquid-biopsy approach called PANXEON that combines multiple blood-based signals rather than […] The post A new blood test...
• The result is promising, but it is not a new screening test you can request at your next physical.
• The technology still needs prospective validation in the kinds of people who would actually be screened.
