Ovarian Cancer is characterized by abnormal growth of cells in the ovaries causing internal reproduction organs that produce the egg cells in women. There could be many reason for ovarian cancers some of them being inherited genetic mutations, women with history of breast cancer or family history of breast or ovarian cancer, long term exposure of elevated estrogen levels; early age of menstruation (prior to 12 years), late onset of menopause (after age 52), absence of pregnancy (childlessness), and the use of fertility drugs.
Surgical removal of the ovaries is a serious surgery that, in addition to resulting in infertility, will also cause women immediately to go into menopause. This is not a problem in many cases, however, as ovarian cancer usually strikes after menopause.
