Duct ectasia in a younger woman: what to know

Duct ectasia happens when a milk duct beneath the nipple widens and its lining becomes irritated. Thick fluid may collect in the duct, leading to green, yellow, brown, or blood-stained discharge. The area can feel sore or firm, and inflammation can create a lump behind the nipple. Duct ectasia itself is not breast cancer, but similar symptoms can have other causes, so the finding should not be self-diagnosed.

Age does not rule duct ectasia in or out. Your clinician may ask whether the change is in one breast, whether discharge appears without squeezing, and whether you have fever, nipple inversion, skin change, recent breastfeeding, or a history of breast procedures.

Arrange a breast assessment if discharge or a lump persists, recurs, or is new for you. The clinician may examine the breast and nipple and choose imaging based on your age, examination, and symptoms. A breast ultrasound can show the ducts and nearby tissue and may be used when a younger breast needs focused assessment. Keep the nipple clean, avoid repeated squeezing to check for discharge, and note its colour, amount, and timing.

Seek prompt medical care for spontaneous bloody discharge, a new or enlarging lump, nipple pulling inward, skin dimpling, marked redness, or a wound that does not settle. Fever, increasing warmth, swelling, or worsening pain may indicate infection and needs timely review. Go urgently if you feel very unwell or develop rapidly spreading breast redness.

Ask: Does the examination fit duct ectasia or another cause? Do I need a breast ultrasound? What should I do if discharge continues? Which changes should prompt an earlier review?
