Causes of Ovarian Cancer

It’s not entirely clear what causes ovarian cancer to develop, but scientists have several theories. The most accepted is that repeated ovulation leads to cycles of repetitive damage and repair of the cells lining the ovary. This can theoretically ‘jump start’ the cancerous process at the cellular level. Other theories suggest that high levels of several hormones, such as estrogen and testosterone, can lead to multiplication of ovarian epithelial cells which can become unregulated, potentially developing into cancer.
