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.
Although menopause is not a medical illness, the hormonal changes can cause physical and emotional symptoms. Menopause may occur naturally due to a decrease in the reproductive hormones estrogen and progesterone, which regulate menstruation. It may also be the result of a hysterectomy or bilateral oophorectomy.
