Mastalgia (Breast Pain)
The most common type of breast pain is associated with the menstrual cycle and is nearly always hormonal.
Common Benign Lumps
The two 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.

The most common type of breast infection is lactational mastitis, which occurs 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.
