Understanding Prophylactic Salpingo-Oophorectomy for Ovarian Cancer prevention
Table of Contents
For individuals at high risk of ovarian cancer, a preventative surgery called prophylactic salpingo-oophorectomy (PSO) offers a notable reduction in risk. Surgeons are increasingly advocating for this procedure, particularly for those with genetic predispositions or a strong family history of the disease. As of November 20, 2025, research continues to solidify PSO as a powerful tool in cancer prevention.
Who is at Risk and Why?
Ovarian cancer is often diagnosed at a late stage, making it challenging to treat effectively. Approximately 20% of ovarian cancers are linked to hereditary factors, most commonly mutations in the BRCA1 and BRCA2 genes. However, even without a known genetic mutation, a strong family history-specifically, having a first-degree relative (mother, sister, or daughter) diagnosed with ovarian, breast, or pancreatic cancer-can elevate risk.
The Procedure: What Does PSO Involve?
Prophylactic salpingo-oophorectomy involves the surgical removal of the fallopian tubes (salpingectomy) and ovaries (oophorectomy). The procedure is typically performed laparoscopically, utilizing small incisions, which leads to a faster recovery time compared to traditional open surgery. surgeons emphasize that removing the fallopian tubes is a crucial component, as high-grade serous ovarian cancer-the most common type-is believed to originate in the fallopian tubes in many cases.
How Effective is PSO?
Studies have demonstrated a significant reduction in ovarian cancer risk following PSO. Research presented at the 2023 American Society of Clinical Oncology (ASCO) Annual Meeting indicated that PSO can prevent approximately 80% of ovarian cancers in women with harmful mutations in the BRCA1 or BRCA2 genes. Even in women without known mutations but with a strong family history, PSO can reduce risk by as much as 40-60%.
| Risk Factor | ovarian cancer Risk Reduction with PSO |
|---|---|
| BRCA1/2 Mutation | Approximately 80% |
| Strong Family History (No Known Mutation) | 40-60% |
Considerations and Potential Side Effects
While highly effective, PSO is not without its considerations. Removing the ovaries induces surgical menopause, which can lead to symptoms such as hot flashes, vaginal dryness, and mood changes. Hormone replacement therapy (HRT) can be discussed with a physician to manage these symptoms, but its use requires careful evaluation of individual risk factors. There is also a small risk of surgical complications, as with any major surgery.
“The decision to undergo PSO is deeply personal and should be made in consultation with a healthcare team, including a genetic counselor, gynecologic oncologist, and primary care physician.”

The optimal age for PSO varies depending on individual risk factors and genetic testing results. generally,it is considered for women who have completed childbearing,typically between the ages of 35 and 50.
