Breast Cyst

The Challenge

Cystic breast masses are frequently encountered during the clinical care of women. The challenge is sorting out those that represent a threat from those that may be conservatively followed up.

• Scope of the Problem: Some authors estimate that cysts form in the breasts of approximately 50% of women during their reproductive years. Roughly one in four women requires medical attention for some form of breast problem; often this takes the form of a palpable mass. The most common cause of a palpable breast cyst is fibrocystic change, which is estimated to be found in one-third to three-fourths of all women. Dilation of ducts and complications of breastfeeding (galactoceles, abscess) may also cause cysts. About 70% of cysts will regress in 5 years.

• Objectives: To appropriately diagnose and treat patients with a cystic breast, allay fear, and protect health.
