Circulating tumor cells are detectable in the bloodstream of early-stage cancer patients.
Is it true that circulating tumor cells are detectable in the bloodstream of early-stage cancer patients?
Yes. Multiple studies and reviews demonstrate that circulating tumor cells and tumor-derived components are indeed detectable in the bloodstream of patients with early-stage or localized cancers.
Verdict: SUPPORTED · 8 sources for, 0 against · Last checked
The retrieved literature consistently supports the claim that circulating tumor cells and related liquid biopsy markers can be detected in early-stage cancer patients, forming the basis for minimally invasive diagnostics.
