Thinking about cancer or dealing with cancer risk can be scary or overwhelming, but we believe that receiving information and resources is comforting, empowering, and lifesaving.
Emerging research suggests that the fallopian tubes may be the source of many hereditary ovarian cancers. This has led researchers to study if premenopausal women could remove their fallopian tubes and delay ovarian removal until after menopause. Several pieces of evidence point to ovarian cancers starting in the fallopian tubes:
Even if the fallopian tubes are the cause of many gynecologic cancers in mutation carriers, researchers caution that there is not enough evidence to suggest that all of these ovarian cancer start in the fallopian tubes. Also removing just the fallopian tubes is not likely to lower the risk for breast cancer. More research is needed to completely understand the role of the fallopian tubes in the development of these cancers. A national research study called the WISP Study is looking at outcomes for high-risk women who remove their fallopian tubes only, followed later by removal of the ovaries.
Tubal ligation, also known as “tying your tubes” seals the fallopian tubes, preventing eggs from reaching the uterus. Some experts believe this may lower ovarian cancer risk. However, national guidelines recommend that women at high risk for ovarian cancer due to BRCA mutations have their ovaries and fallopian tubes surgically removed by age 35-40 or after the completion of child bearing.
