Abstract
What is already known about this subject? Non invasive prenatal testing for fetal trisomies 13, 18, and 21 occasionally identifies maternal cancer.What does this study add? - A further case of maternal cancer incidentally diagnosed by routine NIPT. - Extensive NIPT abnormalities are unlikely to be of fetal origin. - Information given to patients should also adequately advise patients on potential incidental findings and might offer the option to opt out of receiving results beyond the trisomy report. - International guidelines would improve patient counseling.
