Uterine fibroids, are also called leiomyomas. Leio- means smooth, myo- means muscle, and -oma means tumor, so these are benign smooth muscle tumors of the uterus.
In fact, fibroids are the most common type of tumor in females.
The uterus is a hollow organ that sits behind the urinary bladder and in front of the rectum.
The top of the uterus above the openings of the fallopian tubes is called the fundus, and the region below the openings is called the uterine body.
The uterus tapers down into the uterine isthmus and finally the cervix, which protrudes into the vagina.
Zooming into the cervix, there are two openings, a superior opening up top, and an inferior opening down below, both of which have mucus plugs to keep the uterus closed off except during menstruation and right before ovulation.
The uterus is anchored to the sacrum by utero- sacral ligaments, to the anterior body wall by round ligaments, and it’s supported laterally by cardinal ligaments as well as the mesometrium, which is part of the broad ligament.
The wall of the uterus has three layers: the perimetrium, which is a layer continuous with the lining of the peritoneal cavity, the myometrium, which is made of smooth muscle that contracts during childbirth to help push the baby out, and the endometrium, a mucosal layer, that undergoes monthly cyclic changes.
Summary
Uterine fibroids, also called leiomyomas, are non-cancerous growths that develop in the uterus, most commonly in women of childbearing age. The exact cause of uterine fibroids is unknown, but they are thought to be related to hormonal imbalances and genetic factors.
Uterine fibroids can cause symptoms such as heavy menstrual bleeding, pelvic pain or pressure, and frequent urination. In some cases, they can also lead to infertility or complications during pregnancy. Treatment options may include medications to regulate hormones or shrink the fibroids, or surgical procedures to remove them. In some cases, no treatment is necessary if the fibroids are small and not causing symptoms.
