Which condition involves pain and inflammation of the breast?

Mastitis is characterized by pain and inflammation of the breast tissue, often occurring in women who are breastfeeding. This condition typically arises when bacteria enter the breast tissue, leading to infection. Symptoms include swollen, red, and warm skin over the affected area, as well as tenderness and a potential fever. The inflammation can also cause milk ducts to become blocked, which can exacerbate the discomfort and pain.

In contrast, fibrocystic breast disease involves the presence of non-cancerous changes in breast tissue often presenting as lumps or cysts, but it does not typically involve significant inflammation or acute pain like mastitis does. Breast cancer can cause discomfort or changes in the breast, but it often presents with more gradual symptoms and does not primarily involve inflammation. Galactorrhea refers to the inappropriate production of milk, which can occur due to hormonal imbalances, but it is not primarily associated with inflammation or significant breast pain. Hence, mastitis stands out as the condition specifically linked to both pain and inflammation in the breast.
