what causes ovarian cancer

The exact cause of ovarian cancer is unknown, but certain factors are thought to increase a woman's risk of developing the condition. These factors include age, inherited faulty genes such as the BRCA genes or those linked to Lynch syndrome, a history of breast or bowel cancer, endometriosis, and certain lifestyle factors such as smoking and being overweight. Some theories suggest a relationship between ovulation and the risk of developing ovarian cancer, as well as the role of hormonal factors and the number of eggs the ovaries release
