Epithelial lined fluid-filled cavities, which form when lobules become distended due to blockage, usually in the perimenopausal age group
Aetiology
- Commonly occur during the late reproductive years of a woman’s life
Clinical presentation
- Can present singularly or with multiple lumps and can affect one or both breasts
- A cyst is typically palpable, clearly defined, soft, mobile, and smooth, with distinct borders
- Cysts are often somewhat tender, especially before menstruation
Investigations
- Cysts can be identified by their typical halo shape on mammography
- Can usually be definitively diagnosed using ultrasound
- Persisting, symptomatic, or undeterminable cystic masses may be aspirated
- Cancer may be excluded if the fluid is free of blood or the lump disappears, otherwise the cystic fluid should be sent for cytology
Management
- Once diagnosed, cysts usually require no further management and self-resolve, however women are at a higher risk of these recurring
- Larger cysts can be aspirated for aesthetic reasons or patient reassurance
