Question: Will my menstrual periods be regular during my chemotherapy treatments for breast cancer?
Answer: Many premenopausal women will have disruption of their menstrual periods because of chemotherapy for breast cancer. That can be a permanent or a temporary thing, and so sometimes the menstrual periods will come back and sometimes they won't. The risk factors for having problems with your periods during chemotherapy include being older -- so women in their 40s are more likely to have this problem than women in their 30s. And it also depends on the type of chemotherapy that you're actually getting and for how long you get the chemotherapy treatment.
