The cause of ovarian cancer in humans body

The cause of ovarian cancer is unknown, but there are certain risk factors that indicate an increase in a woman's chance of developing ovarian cancer. The following have been suggested as risk factors for ovarian cancer:

* early menarche - starting monthly periods early - before the age of 12
* late menopause (after the age of 52)
* age - over the age of 50
* hormone replacement therapy
Some studies have suggested that women who use hormone replacement therapy after
menopause may have a slightly increased risk of ovarian cancer.
* infertility (inability to become pregnant)
* having a first child after the age of 30
* personal history of breast or colon cancer
* family history
First-degree relatives (such as mother, daughter, sister) of a woman who has had ovarian cancer are at risk for developing the disease. The risk increases if two or more first-degree relatives have had ovarian cancer. A family history of breast or colon cancer is also associated with an increased risk of developing ovarian cancer.
