Cystic breasts after menopause: what to know

A cyst is a fluid-filled space that may feel smooth, round or mobile. Hormone changes associated with menopause can alter breast tissue, and hormone medicines may also affect breast symptoms. These facts do not identify a particular lump. A clinician considers its texture, position, duration and associated skin or nipple changes.

Breast symptoms should be assessed even when there are no other menopause symptoms such as hot flushes, night sweats or vaginal dryness. A breast examination and appropriate imaging can distinguish a simple fluid-filled finding from a solid or mixed area.

Book an appointment for any new breast lump, especially if it remains present, enlarges or feels different from the surrounding tissue. Record when you first noticed it and whether there is pain, discharge or a visible change. Do not massage or puncture the area. Take a list of prescribed hormones and other medicines to the appointment.

The clinician may recommend monitoring, imaging, or sampling or drainage depending on the findings. Continue any routine breast checks advised for your age and personal history.

Seek prompt care for a hard or fixed lump, skin dimpling, an orange-peel texture, new nipple inversion, bloody discharge, redness with warmth, or swelling in the breast or armpit. Fever or feeling acutely unwell with breast inflammation also warrants prompt attention.

Ask: What features make this look cystic? Which examination or imaging is appropriate? Could my hormone treatment affect the symptom? Should the area be monitored, drained or sampled, and when should I return?
