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.
Although most endometriomas are found to be benign, the possibility of malignant tumors still exists, and surgery is needed to confirm malignancy and determine what future treatment must be administered. Another factor that endometrioma can impact is the ovarian reserve, or the number of quality follicles left in the ovary to produce viable ...
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.
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]
Thecomas or theca cell tumors are benign ovarian neoplasms composed only of theca cells.Histogenetically they are classified as sex cord-stromal tumours.. They are typically estrogen-producing and they occur in older women (mean age 59; 84% after menopause).
Of course, there are probably other essential hormonal interactions that are interrupted, too, but that area is another scientific black hole, and progress has been slow due to a lack of research ...
Ovarian cystadenoma is a cystic benign tumor of the ovary. [1] Two types are recognized: serous and mucinous. Ovarian cystadenomas are common benign epithelial ...
Benign tumor growth causes a mass effect that can compress neighboring tissues. This can lead to nerve damage, blood flow reduction ( ischemia ), tissue death ( necrosis ), or organ damage. The health effects of benign tumor growth may be more prominent if the tumor is contained within an enclosed space such as the cranium , respiratory tract ...
