What is the abnormal development of breast tissue during pregnancy known as?

The correct term for the abnormal development of breast tissue during pregnancy is not mastitis. Mastitis refers to an infection of the breast tissue, often associated with breastfeeding, which can lead to pain, swelling, and sometimes fever. It does not describe abnormal growth or changes in breast tissue specifically related to pregnancy.

The other options provide different conditions: fibrocystic breast changes describe non-cancerous changes in breast tissue that can cause lumps or discomfort, but this is not classified as an abnormal development due to pregnancy specifically. Breast cancer is a serious diagnosis characterized by the uncontrolled growth of cells in the breast tissue but is unrelated to normal breast changes during pregnancy. Galactorrhea is the inappropriate discharge of milk from the breasts, which can occur for various reasons but does not directly refer to the abnormal development of breast tissue itself.

Thus, identifying the specific type of abnormal development of breast tissue during pregnancy requires an understanding of the term that encapsulates this phenomenon, which is distinct from these other conditions.
