Certain types of cancer treatments can cause women to have early menopause. This is menopause that occurs before age 40. It happens when your ovaries stop working and you no longer have periods or cannot get pregnant. Early menopause can cause symptoms such as hot flashes and vaginal dryness. Your health care provider can help you find treatments for these symptoms.
With the onset of menopause, however, the amount of natural estrogen and progesterone the ovaries produce drops sharply. That, in turn, can lead to such symptoms as hot flashes, night sweats, vaginal dryness, painful intercourse, mood changes, and sleep problems. It also can boost the risk of osteoporosis.
