Typically, patients present with one or more lumps in the breast which may be painful, and frequently, bilateral. The size and pain usually vary with the menstrual cycle. One or more of these elements may be absent.
Cysts are more common in perimenopausal women. They are usually single. The presence of multiple, diffuse cysts may be referred to as Schimmelbusch's disease. The discharge varies from clear to green but should not be bloodstained.
On palpation, a cyst may be recognised by its smooth texture and characteristic tense fluctuation.
