A study found that prenatal cfDNA screening test results showing abnormalities unrelated to fetal chromosomes were linked to a subsequently diagnosed cancer in about 50% of cases in that subgroup.
Notes on verification
Confirmed by original peer-reviewed NEJM study, NIH press release, and independent academic review citing consistent figures (48.6%, 52/107).
