Summarizing the Risks of Hysterectomy

When a women has surgery to remove her uterus, and way too often her healthy ovaries at the same time, she increases her risk of dying prematurely, diminishing her sex life, and suffering from a host of other health problems.

Here's a quick summary of the Risk Increase shown by some of the research, with sources:

Hysterectomy Alone

• Incontinence: 60% greater risk by age 60 than an intact woman ("Vital Signs: Consequences; Hysterectomy and Risk of Incontinence." The New York Times, Aug. 22, 2000. By Eric Nagourney
• Coronary Heart Disease: 3 times grater risk if hysterectomy done before menopause (American Journal of Obstetrics & Gynecology, Jan. 1981; 139 (1):58-61)

Oophorectomy (removal of ovaries)

• Early Death: twice the risk if ovaries removed before age 45 and no estrogen replacement given ("Survival patterns after oophorectomy in premenopausal women: a population-based cohort study." Lancet Oncology Volume 7, Issue 10, 2006, pp.821-828; by W.A. Rocca, MD, and others.)
• Dementia: 33% higher over all than women who keep their ovaries through menopause; 74% higher if her ovaries are removed on or before age 43 ("Increased risk of cognitive impairment or dementia in women who underwent oophorectomy before menopause." Neurology 2007; 69:1074-1083; by W.A. Rocca, MD, and others)
• Heart Attack: double the risk if a woman loses her ovaries between the ages of 40 and 44; 40% higher if ovaries removed after age 50 ("Ovarian Conservation at the Time of Hysterectomy for Benign Disease." Obstetrics & Gynecology, Vol. 106, No.2, Aug. 2005
• Bone fractures from osteoporosis: 54% more fractures when ovaries removed after menopause (same study, Ovarian Conservation, etc., cited above)

This is not a list you will find in any of the literature given out by gynecologists. Nor, when they try to talk women into letting them take out their ovaries while doing the hysterectomy, will they reveal that the average woman's risk of ovarian cancer is 1 in 72 (or 1.39% over her lifetime). By comparison, the lifetime risk of breast cancer is 1 in 8 (or 12.15% over her lifetime).

Of course, some women have genetic and family risk factors for ovarian cancer that make their decision much more difficult. I feel for them. But for other women, a gynecologist who uses the fear of ovarian cancer to convince her to consent to ovary removal is nothing less than unethical. Such a doctor should do women the favor of finding some other line of work.

Evidence Ignored by Doctors Removing Women's Ovaries

I have been deeply affected by the comments of women in response to my last blog about hysterectomy. Their lives have been devastated by--what should I call them? Ignorant? Arrogant? Unethical? Unprofessional? All of these?--doctors who continue to remove healthy ovaries from women in the face of evidence that they are causing irreparable harm to their patients.

Spurred by these comments, and by my need to prepare to attend the HERS Hysterectomy Conference this coming Saturday, I did some research and found a smoking gun right on the website of the American College of Obstetricians and Gynecologists. It's an August, 2005 article (scroll down the search page to the 7th article) that appeared in the journal Obstetrics & Gynecology. Apparently, it's not required reading for the practicing physicians who continue to castrate women.

Called "Ovarian Conservation at the Time of Hysterectomy for Benign Disease," it takes a comprehensive look at the risks and benefits of removing a woman's ovaries at the same time that she has a hysterectomy for non-cancerous problems like fibroids and heavy bleeding. As far as I can tell at this point, it appears to be one of the latest investigations of the issue, which, despite its importance to women, has not been the subject of much research at all.

Here are some of the conclusions:

• At no age is there any clear benefit to women from removal of the ovaries (oophorectomy).
  
• "For women younger than 65 at the time of surgery, oophorectomy increases the risk of dying from coronary heart disease."
• Evidence from the Nurses' Health Study says that the risk of heart attack was doubled if the women in question were between 40 and 44 years old; and up 40% if the women were older than 50.
• After losing their ovaries, women have higher bad cholesterol levels, higher blood pressure and more hardening of the arteries.
  
• Women who were past menopause when they had an oophorectomy ended up with 54% more bone fractures due to osteporosis than women with intact ovaries.
• The fractures often were of the hip, and having a hip fracture between ages 60 and 64 meant dying early--a loss of 11 years of life!
• It also means that many of those women could never leave their homes again on their own. One study found that before breaking a hip, 28 percent of the women were housebound; after the fracture, 46 percent were housebound.
  

So why do doctors continue to castrate women?

I certainly have no satisfactory answer to that.

But some, apparently, believe that the overriding benefit is to reduce a woman's chance of getting ovarian cancer. But this study notes that removal of the uterus alone lowers the risk of ovarian cancer by 40% below the level of women who retain their uterus.

So, let's see: since men have a risk of testicular cancer, should doctors be removing their testicles just in case? Or treating them with female hormones to reduce the risk of prostate cancer?

We women know that would never happen. Men prize their virility and do everything to keep it. Women prize their sexuality, too, but consent to hysterectomy and oopherectomy too often without realizing what they will be giving up. Thus the need for the HERS Foundation video and consent only after seeing it.

So, is it ignorance of the facts that keeps doctors castrating women? Or what? Theories--and certainly facts--welcome.
