A galactocele is best defined as which of the following?

A galactocele is accurately defined as a milk-retention cyst. This condition occurs when there is an obstruction in the milk ducts, typically leading to the accumulation of milk that forms a cystic structure within the breast tissue. These cysts can be palpable and may vary in size, often appearing as non-tender masses.

Understanding the nature of a galactocele is important for clinical assessment and management, especially in breastfeeding individuals. As a milk-retention cyst, its primary characteristic is the retention of milk, which distinguishes it from other conditions related to breastfeeding complications. While breastfeeding complications may lead to other issues such as pain or infection, a galactocele is specifically related to an accumulation of milk rather than inflammation or engorgement, which is why this definition is most accurate.
