Unusual NIPT findings from Pregnancy testing is resulting in the detection of certain cancers. 

During their pregnancy, Pregnant women must undergo blood testing to make sure the fetus is healthy and doesn’t carry any chromosomal disorders. This type of testing is called noninvasive prenatal testing (NIPT) which has been found to have unusual results not from the fetus, but the Mother’s DNA. Using a study of more than 100 women who found abnormal changes, nearly half of them were found to have cancers like colorectal, breast, lung cancer etc. It is critical that all women should go through whole- body imaging to detect these cancers at an early stage to provide necessary treatment. They hope to develop more accessible cancer screening that is useful in seeing if there are any risks for cancer in the Mother’s DNA pattern. 

Importance: This article is important in raising awareness for the possibility of mothers to develop cancer during their pregnancies and how symptoms are not clear enough to detect them easily. I believe that all women, especially those that are in critical times like pregnancy, should have full accessibility to care that clearly provides them with a detailed plan of their health. By acknowledging this issue in the Mother’s DNA, oncologists and maternity specialists can be more aware early on to help treat cancers that have affected people worldwide. 

I learned an interesting fact that the mother’s blood contains fragments of DNA shed from her own cells! Some raising questions that passed my mind are: Is there any medical equipment being developed that is specialized in detecting cancers in pregnancy? How does the development of cancers in the Mother’s DNA impact the fetus later on?

Vocab: 

Aneuploidy:  An extra or missing chromosomes in a cell or organism

Oncology: The study, diagnosis, and prevention of the treatment of cancer

Asymptomatic: Not being presented with symptoms
