a. Cysts within the breast are fluid-filled, epithelium-lined cavities that may vary in size from microscopic to large, palpable masses containing as much as 20 to 30 mL of fluid.
b. A palpable cyst develops in at least 1 in every 14 women, and 50% of cysts are multiple or recurrent.
c. The pathogenesis of cyst formation is not well understood; however, cysts appear to arise from destruction and dilation of lobules and terminal ductules.
d. A palpable mass can be confirmed to be a cyst by aspiration or ultrasound. Cyst fluid can be straw colored, opaque, or dark green and may contain flecks of debris.
e. If the cyst recurs multiple times (more than two times is a reasonable rulE., cytology is justified. Surgical removal of a cyst is usually indicated if the cytologic findings are suspicious or the cyst recurs multiple times.
