What is Ovarian cancer?
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).
In 2004, in the United States, 25,580 new cases were diagnosed and 16,090 women died of ovarian cancer. The risk increases with age and decreases with pregnancy. Lifetime risk is about 1.6%, but women with affected first-degree relatives have a 5% risk. Women with a mutated BRCA1 or BRCA2 gene carry a risk between 25% and 60% depending on the specific mutation.[5] ovarian cancer is the fifth leading cause of death from cancer in women and the leading cause of death from gynecological cancer.[6]
In early stages ovarian cancer is associated with abdominal distension.[7]
