Breast cysts during menopause

A cyst may feel smooth, round or oval, and sometimes tender. It may move slightly under the skin, although touch alone cannot confirm what a lump is. Cysts are linked to fluid collecting in breast tissue and can still occur during the transition to menopause. A lump arising after periods have stopped should not be assumed to be a cyst without examination.

A clinician may examine both breasts and the nearby lymph-node areas. Ultrasound can show whether a lump contains fluid or is solid; mammography or another test may be recommended according to the examination and your personal history.

Arrange a breast assessment for a new or changing lump. Note when you first noticed it, whether it is painful, and whether its size changes. Tell the clinician about hormone medicines, previous breast problems, breast procedures, and relevant family history. Avoid repeatedly squeezing the area, because this can increase tenderness without identifying the cause.

If imaging confirms a simple cyst and it is comfortable, observation may be enough. A clinician may drain a painful or large cyst with a needle. Fluid returning, a persistent mass after drainage, or an unusual imaging appearance can lead to further assessment.

Book a prompt appointment for any new breast lump, especially after menopause, or for a lump that grows, feels fixed, or does not settle. Seek earlier review if there is skin dimpling, nipple pulling inward, bloody nipple discharge, redness that spreads, or a new swelling in the armpit. Fever with a hot, red, painful breast needs urgent assessment because infection may require treatment.

Ask whether the examination suggests a cyst, which imaging is suitable, and how you will receive the results. You can also ask what change should trigger another appointment, whether drainage might help discomfort, and whether your hormone treatment or breast history affects the follow-up plan.
