If you are planning your hysterectomy, or even just investigating what it would mean for you, and your doctor offers you this "recommendation," you may want to ask him to step back and explain himself in a lot more detail.
It used to be the practice that when women were facing a hyst, a surgeon would suggest that because her ovaries "aren't needed" any more, she should have them removed now so as to remove the risk of later getting ovarian cancer. In many cases, this would include the suggestion that "most" women who retain ovaries only end up needing another surgery later to remove them anyway.
Today we know that this kind of a sales pitch is not only medically inaccurate but is in fact a strategy that holds greater odds of shortening a woman's life than the alternative. And, slowly, doctors who keep up with the news in this field are revising their recommendations to a more accurate representation of the various risks.
Much of this turnaround can be credited to this study, published in the May, 2009 issue of the journal Obstetrics & Gynecology: "Ovarian Conservation at the Time of Hysterectomy and Long-Term Health Outcomes in the Nurses’ Health Study." For something that may be a little less intimidating to read, you might try this article at webmd: "Hysterectomy: Spare Ovaries, Boost Health?." Yet another good resource is the anonymous but probably related to the study website OvaryResearch, which focuses on the study and discussion it's stimulated as well as an earlier version of it that appeared in 2005.
Okay, enough with the citations: what's this about?
The study, which involved a very large pool of women (that's good, because it means the results are more likely to really reflect us all), found that rather than lowering deaths from cancer, prophylactic oophorectomy (that's the fancy way of saying taking out ovaries for the sake of prevention) in fact had a higher risk of death from all causes but mostly heart disease and lung cancer. That's right: removing our healthy ovaries at any age does not lengthen our lives or improve our health.
Further, although breast and ovarian cancer rates were lower in women who had their ovaries removed, the risk of death from all types of cancer was higher in these women. So, yes, the very thing we feared and chose this option in hopes of preventing is actually more likely to happen to us than if we'd left well enough alone.
And the rates of death are highest for women who never supplemented their hormones after the surgery. All those women who valiently toughed out menopausal symptoms because they thought it was the right and "natural" thing to do were in fact working with their doctors to shorten their own lives.
Tragic, right? And we're talking a big tragedy here: about 300,000 women a year choose to have this surgery under the impression that it will help them live longer, healthier lives. According to the main study author, that's "50% of women who have a hysterectomy between ages 40-44...and 78% of women between ages 45-64," even though it's well demonstrated that post-menopausal ovaries continue to contribute to our hormonal support, a support that's lost when we take those ovaries out.
But wait! What about women at real risk for cancer?
Yes, of course there are women for whom the risks boil down to high expectation of death by breast or ovarian cancer vs later death by these risks of lost hormones. That's a special situation and no one is suggesting that preventative removal of ovaries might not be the right choice for them.
But it needs to be an informed choice. That means not just making the assumption that because there's "a lot of cancer" in one's family that we are, personally, at risk for these specific cancers. It requires genetic testing and evaluation by an oncological specialist, not an assurance of a gyn surgeon who heard the word "cancer" and got spooked into a slash-and-burn mentality.
Can't I just take something to make up for that risk?
For many of us, the idea of cancer is so terrifying that it shorts out our brains. Especially if we're younger women and few of our peers have died of things we attribute to aging, we may not feel that the risk of heart attack or stroke is all that vivid or personal.
One of the objections to the recommendations of this study, that more women keep healthy ovaries, is that this risk can be treated medically with statins, drugs that lower cholesterol and lipids that are believed to be a major cause of heart disease, and bisphosphonates, drugs that preserve bone density. As the study author replies, however, these drugs have notorious dropout rates, just as HRTs do. Taking out a healthy body part and replacing it with drugs that must be taken for the rest of our lives and may have significant side effects of their own: if we look at it that way, how much sense does that make?
And then there are the women who want to do it "all naturally." What do they do? Exercise and healthy eating are important lifestyle strategies for minimizing cardiovascular and osteoporosis risks, but alone they probably aren't enough for most women, not to mention that they too are something that sounds better in concept than they are actually adhered to for every remaining day of our lives. Menopausal nutraceuticals, the raw plant estrogenic compounds that are sold to reduce hot flashes in natural menopause, are relatively ineffective in coping with the level of symptoms seen with the larger drop in hormone levels due to ovarian removal. And they entirely fail to address many of the more serious effects of hormone deficiency...such as the ones that lead to the risks cited in the study. In fact, this is not a natural situation and there is no natural solution that makes up for it.
But my ovaries are diseased: what should I do?
No one is suggesting that women should not treat existing ovarian disease with surgery. But this study does suggest that we should balance our treatment options against the risks, and those risks are more sizable than our previous understanding led us to believe.
Some ovarian disorders don't require removing the whole ovary to treat, and these are poorly paid back by the increased risks.
But some disorders do require removal for definitive treatment. Sometimes, other diseases are best treated by removing our ovaries. In these cases, however, we still need to understand the costs of that treatment and we need to understand how to mitigate those costs, whether that's drugs or HRT or simply accepting that we have chosen that direction for our lives rather than the one that would have resulted from our ovarian disease.
We need to know that not having ovaries means more than not having ovarian disease.
You have to make up your own mind
This is a complex issue. Many things that can go wrong with our ovaries still don't require that we give up our ovaries. Nothing going wrong with our ovaries really doesn't seem to require their loss. The things at the other side of that equation, heart and lung disease chief among them, kill many, many more women every year.
Just as we don't necessarily believe the car salesman that the extras he's recommending will do anything more than provide him with higher profits, so we shouldn't necessarily believe the person we'll be paying to do our surgery that the extras he's recommending are more valuable to us than him. This is where second opinions are so important, getting an opinion from a doctor who doesn't profit from that advice. And where we're worried about cancer risks, we should talk with an oncologist to make sure we're evaluating our own risk accurately and not just spooked by the word itself.
This study did nothing to simplify our decision with respect to a hyst except for one thing: we simply shouldn't accept "as long as you're having a hyst" as a good reason to give up our ovaries. Because when you hear that phrase, you now know enough to hear the unspoken rest of it: "as long as you're having a hyst, why not let me give you a higher chance of an early death by heart disease or cancer?" And we simply don't need that.
