Common Breast Conditions

There are 2 main types of breast pain. The most common type is linked to the menstrual cycle and is almost always hormonal.

The 2 most common types of benign breast lumps are cysts and fibroadenomas. A cyst is a fluid-filled sac that develops in the breast tissue. Fibroadenomas are solid, smooth, firm, benign lumps that are most commonly found in women in their late teens and early 20s.

Nipple conditions are a common noncancer (benign) breast condition affecting many women. Some problems are related to lactation, and others are not.

The most common type of breast infection is lactational mastitis. This happens when a woman is breastfeeding. The nipples become cracked and sore, allowing bacteria from the baby's mouth to enter the ducts and rapidly multiply in the milk.

To diagnose a breast condition, your healthcare provider will examine your breasts and may order imaging tests or a biopsy.
