ctDNA
circulating tumor DNA — Fragments of tumor DNA in the blood, used for non-invasive cancer detection and monitoring.
Coverage of ctDNA is holding steady : 11 signals on the latest tracked day, down 61% from its three-week baseline of 28, across 3 domains (unchanged from a week ago). That makes it the #249 most-covered of the 348 concerns we track.
What’s changed
7 of the last 7 tracked days ran below the three-week baseline — a sustained cooling, not a one-day dip.
