Ovarian cancer forms when errors in normal ovarian cell growth occur. Usually, when cells grow old or get damaged, they die, and new cells take their place. Cancer starts when new cells form unneeded, and old or damaged cells do not die as they should. The buildup of extra cells often forms a mass of tissue called an ovarian tumor or growth.
Ovarian tumors, or ovarian neoplasms, are tumors in the ovary. [1] Not all are ovarian cancer. [1] They consist of mainly solid tissue, while ovarian cysts contain fluid. [2]In 2020, the World Health Organization (WHO) divided ovarian tumours as 90% epithelial, 3% germ cell, and 2% sex cord-stromal types.
Since 1975, survival rates for ovarian cancer have steadily improved with a mean decrease of 51% by 2006 of risk of death from ovarian cancer for an advanced stage tumour. [58] The increase has mainly been due to successful extended life expectancy of affected patients rather than an improvement in cure rates.

Ovarian fibroma (white part on the left) The ovarian fibroma, also fibroma, is a benign sex cord-stromal tumour. Ovarian fibromas represent 4% of all ovarian neoplasms. [1] They tend to occur mostly during perimenopause and postmenopause, the median age having been reported to be about 52 years, and they are rare in children. [1]
Benign mucinous tumors are typically multilocular (have several lobes), and the cysts have a smooth lining of epithelium that resembles endocervical epithelial cells with small numbers of gastrointestinal-type epithelial cells. Borderline and malignant mucinous tumors often have papillae and solid areas. There may also be hemorrhage and necrosis.
By unraveling the mysteries of ovarian aging (which reaches a zenith in menopause), we can better understand what role our ovaries play in our overall health, wellness, and lifespan.“The ovaries ...
Ovarian cystadenoma is a cystic benign tumor of the ovary. [1] Two types are recognized: serous and mucinous . Ovarian cystadenomas are common benign epithelial neoplasms that carry an excellent prognosis.
