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] Lesions tend to be asymptomatic.
Uterine fibroids, also known as uterine leiomyomas, fibromyoma or fibroids, are benign smooth muscle tumors of the uterus, part of the female reproductive system. [1] Most people [note 1] with fibroids have no symptoms while others may have painful or heavy periods. [1]
Endometriomas can increase the risk of ovarian cancer in reproductive women, decrease normal ovarian function, and cause pain in the pelvis during or after periods or during sexual intercourse. Although most endometriomas are found to be benign, the possibility of malignant tumors still exists, and surgery is needed to confirm malignancy and ...
