For decades, ovarian cancer prevention has faced a frustrating problem: there is no reliable screening test that finds the disease early enough to save most lives.
But scientists have also discovered something that has changed the prevention conversation entirely. Many of the most common and deadly cancers we call ovarian cancer appear to begin not in the ovaries, but in the fallopian tubes.
That insight has led to a surprisingly practical strategy: for women who have finished having children and are already undergoing certain abdominal or pelvic surgeries, removing both fallopian tubes may substantially reduce future ovarian-cancer risk without removing the ovaries or causing surgical menopause.
The fallopian tubes changed what scientists thought they knew
High-grade serous carcinoma is the most common and lethal form of ovarian cancer. Research increasingly indicates that many of these cancers begin as abnormal cells near the ends of the fallopian tubes before spreading to the ovary and elsewhere in the abdomen.
That discovery turned the fallopian tubes from innocent bystanders into a major target for prevention.
A September 11 UCLA Health review reports that removing both fallopian tubes can reduce ovarian-cancer risk by nearly 80%.
This is called opportunistic salpingectomy
The procedure is known as bilateral salpingectomy: removal of both fallopian tubes. When it is performed during another operation a woman already needs, it is often called an opportunistic salpingectomy.
For example, a woman having a hysterectomy who no longer wants children might have her fallopian tubes removed at the same time. A woman seeking permanent sterilization may choose tube removal rather than simply having the tubes blocked or “tied.”
The idea is to use an operation that is already taking place as an opportunity to reduce future cancer risk.
The ovaries stay in place
This distinction matters enormously.
Removing the ovaries before natural menopause causes an abrupt loss of ovarian hormones and immediate surgical menopause. For women at average ovarian-cancer risk, removing healthy ovaries too early can have important long-term consequences.
Salpingectomy removes the tubes while leaving the ovaries intact. Current evidence indicates that this approach generally does not impair ovarian function or trigger premature menopause.
That is what makes the strategy potentially useful for average-risk women who are already undergoing appropriate surgery.
It is not a reason to schedule surgery solely out of fear
An 80% risk reduction sounds dramatic, but it needs context.
Most average-risk women will never develop ovarian cancer. Surgery has risks, and permanent removal of the fallopian tubes means natural conception is no longer possible.
This is not a recommendation that every woman who has finished having children schedule an operation to remove healthy tubes.
The opportunity is most compelling when a woman is already having a hysterectomy, permanent sterilization or another abdominal or pelvic procedure in which tube removal can reasonably be considered.
Why prevention matters so much for ovarian cancer
Ovarian cancer is particularly difficult because early disease may cause few or nonspecific symptoms, and there is no effective population screening program comparable to mammography for breast cancer or Pap/HPV testing for cervical cancer.

By the time many women are diagnosed, the disease has already spread.
Symptoms can include persistent bloating, pelvic or abdominal pain or pressure, feeling full quickly, and changes in urinary or bowel habits. These symptoms are common and usually have other causes, but new, persistent and progressive symptoms deserve evaluation.
A CA-125 blood test is not a routine screening solution
Women sometimes hear about the CA-125 blood test and wonder why everyone isn’t simply tested annually.
CA-125 can be elevated in ovarian cancer, but it can also rise for many noncancerous reasons, and some ovarian cancers do not produce high levels. Transvaginal ultrasound has similar limitations as a population screening strategy.
For average-risk women without symptoms, these tests have not been shown to reduce ovarian-cancer deaths through routine screening.
That is one reason prevention strategies such as opportunistic salpingectomy have attracted so much attention.
Some women have much higher inherited risk
Women with certain inherited genetic variants—including BRCA1, BRCA2 and genes associated with Lynch syndrome—can face substantially higher ovarian-cancer risk than the general population.
Management for these women is different and may include genetic counseling and risk-reducing removal of both tubes and ovaries at an appropriate age.
A strong family history of ovarian, breast, pancreatic, uterine or colorectal cancer is worth discussing with a clinician because it may change the prevention strategy entirely.
The conversation may matter before hysterectomy or sterilization
If you know you are having a hysterectomy and your tubes are still present, ask whether removing them at the same time makes sense.
If you’re considering permanent contraception, ask how complete salpingectomy compares with other sterilization options in your particular situation.
And if you’re undergoing another abdominal or pelvic surgery, ask whether opportunistic salpingectomy is relevant and whether it would add meaningful surgical risk.
The answer will not be yes for everyone. The important part is knowing the option exists early enough to have the conversation before surgery.
Final word
One of the biggest advances in ovarian-cancer prevention did not come from inventing a better screening test. It came from discovering that scientists may have been looking at the wrong organ.
Recognizing that many deadly “ovarian” cancers begin in the fallopian tubes creates an opportunity to prevent some cancers before they ever develop.
For women who have completed childbearing and are already planning an appropriate pelvic or abdominal operation, asking about the fallopian tubes may now be one of the most consequential questions on the pre-surgery list.
If you were already planning a hysterectomy or permanent sterilization, would you know to ask whether removing your fallopian tubes could reduce your future cancer risk?
