Menopause often brings more than physical changes. It also may bring uncertainty about cancer risks and cancer prevention.
We spoke with Therese Bevers, M.D., medical director of MD Anderson’s Cancer Prevention Center, about menopause and cancer.
How does menopause affect a woman’s cancer risk?
Menopause does not cause cancer. But your risk of developing cancer increases as you age. So women going through menopause have a greater chance of developing cancer because they’re older.
How does the age at which a woman starts menopause affect her cancer risk?
Starting menopause after age 55 increases a woman’s risk of
breast cancer and endometrial cancer. That’s probably because she’s been exposed to more estrogen. During a woman’s menstrual cycle, estrogen stimulates the uterus and breast tissue. So the more menstrual periods a woman has, the longer these tissues are exposed to estrogen.
Women who start menopause later also may have an increased risk of
ovarian cancer, possibly because they have had more ovulations.
