Hysterectomy is the surgical removal of all or part of the uterus. In a total hysterectomy, the uterus and cervix are removed. In some cases, the fallopian tubes and ovaries are removed along with the uterus, which is a hysterectomy with bilateral salpingo-oophorectomy. In a subtotal hysterectomy, only the uterus is removed. In a radical hysterectomy, the uterus, cervix, ovaries, oviducts, lymph nodes, and lymph channels are removed. The type of hysterectomy performed depends on the reason for the procedure. In all cases, menstruation permanently stops and a woman loses the ability to bear children.
The most frequent reason for hysterectomy in American women is to remove fibroid tumors, accounting for 30% of these surgeries. Fibroid tumors are non-cancerous (benign) growths in the uterus that can cause pelvic, low back pain, and heavy or lengthy menstrual periods. They occur in 30–40% of women over age 40, and are three times more likely to be present in African-American women than in Caucasian women. Fibroids do not need to be removed unless they are causing symptoms that interfere with a woman's normal activities.
Treatment of endometriosis is the reason for 20% of hysterectomies. The endometrium is the lining of the uterus. Endometriosis occurs when the cells from the endometrium begin growing outside the uterus. The outlying endometrial cells respond to the hormones that control the menstrual cycle, bleeding each month the way the lining of the uterus does. This causes irritation of the surrounding tissue, leading to pain and scarring.
Twenty percent of hysterectomies are done because of heavy or abnormal vaginal bleeding that cannot be linked to any specific cause and cannot be controlled by other means. Another 20% are performed to treat prolapsed uterus, pelvic inflammatory disease, or endometrial hyperplasia, a potentially pre-cancerous condition.
About 10% of hysterectomies are performed to treat cancer of the cervix, ovaries, or uterus. Women with cancer in one or more of these organs almost always have the organ(s) removed as part of their cancer treatment.
