<human>: Is it normal for a woman's breasts to get bigger during pregnancy?
<bot>: No, it is not normal for a woman's breasts to get bigger during pregnancy. Breast size can increase due to hormonal changes in the body, but this is usually temporary and does not last beyond childbirth. If a woman's breasts are increasing in size during pregnancy, she should consult her doctor as this could be an indication of breast cancer.
