Breast cysts are the most common problem in the breast. Breast cysts may be associated with breast pain.

Cysts, which are fluid-filled sacs, are formed as a result of enlargement of the milk duct glands in the breast. It occurs in one in every 14 women and most commonly between the ages of 40-49.

In general, 25 percent of breast masses are cysts. One fifth of cysts are larger than 1 cm. It may be a single cyst or it may consist of many large and small cysts in the breast tissue.

It is often located in the upper-external quadrant of the breast, but it can affect the entire breast tissue and cause complaints in both breasts at the same time.

It usually does not require treatment and can be monitored.

Large cysts that cause discomfort to the patient can rarely be drained with a needle, but this is not an intervention with a permanent effect; it may recur.
