Doctors perform partial or subtotal hysterectomy surgeries because it is believed that leaving the ovaries while removing the fallopian tubes might reduce the risk of patients developing a common form of cancer of the ovaries, according to the Office on Women's Health of the United States Department of Health and Human Services. During a partial hysterectomy, only the upper part of the uterus is removed while the cervix is left in place.
Hysterectomies are performed for various reasons, including abnormal vaginal bleeding, chronic pain in the pelvis, uterine fibroids, ovarian, uterus or cervix cancers and endometriosis, as noted by WebMD. Whether or not the ovaries are removed during the surgery depends greatly on the reason the patient is having the surgery performed.
The most common hysterectomy surgery is a total hysterectomy, where the uterus and cervix are completely removed and the fallopian tubes and ovaries may or may not be removed, depending on the reason for surgery.
In some cases, hysterectomies are necessary, such as having certain forms or cancer or experiencing heavy bleeding. There are other alternatives to a hysterectomy surgery that a primary care physician may suggest before choosing the surgery. Exercising, taking medications for endometriosis or a vaginal pessary are common alternatives to the surgery, depending on the patient's condition. Since a hysterectomy is a major surgery, it is important to discuss it with a primary health care physician and learn about the benefits and risks of it.
