Stem cells are the cause of ovarian cancer

Scientists from MIPT have solved the mechanism of ovarian cancer: it originates in the stem cells of the epithelium. So far, this result has been obtained in mouse models, but scientists hope to find a similar mechanism in humans and use it for treatment.
