Intervention can occur which produces a medical menopause. Often women who are treated for cancer with chemotherapy go into temporary or permanent menopause.Anticancer drugs can damage the ovaries and reduce the amount of hormones they produce. As a result, some women find that their menstrual periods become irregular or stop completely while they are having chemotherapy. The hormonal effects of treatment may cause menopauselike symptoms such as hot flashes and itching, and burning or dryness of vaginal tissues.Damage to the ovaries may result in infertility, the inability to become pregnant. In some cases, the infertility is a temporary condition; in other cases, it may be permanent. Whether infertility occurs, and how long it lasts, depends on many factors, including the type of drug, the dosage given, and the womans age.
