Several scientific studies have shown that abnormal microRNA expression levels varies and creates a unique, specific pattern for each type of cancer, even at the early stages, reflecting the progression of the disease, and whether it's responding to medication or in remission, making microRNAs a perfect, highly sensitive biomarker.
Nekoliko znanstvenih  istraživanja su pokazala da razina abnormalne ekspresije microRNA varira i stvara jedinstveni određeni uzorak za svaku vrstu karcinoma, čak i u ranim stadijima, odgovarajući razvoju bolesti, i bilo da reagira na lijekove ili je u remisiji, microRNA je savršen, visoko osjetljiv biomarker.
