Ovarian cancer is a cancerous growth arising from different parts of the ovary.
Most (>90%) ovarian cancers are classified as "epithelial" and were believed to arise from the surface (epithelium) of the ovary.[1][2] However, recent evidence suggests that the Fallopian tube could also be the source of some ovarian cancers.[3] Since the ovaries and tubes are closely related to each other, it is hypothesized that these cells can mimic ovarian cancer.[4] Other types arise from the egg cells (germ cell tumor) or supporting cells (sex cord/stromal).
