Liesbeth Lenaerts, postdoctoral researcher of the Cancer in Pregnancy research team in Leuven, talked to ecancer in an interview at ESMO Congress 2018 about the NIPT (non invasive prenatal test) which flagged up copy number alterations and cancer in the foetus' parents. The test was then developed and trialled on elderly patients and it was further verified that this test could detect cancer.
In the interview, dr Lenaerts goes into more depth about the nature of these copy number alterations. Watch the ecancer interview here.
