What should you know about intraductal papilloma duct ectasia?

An intraductal papilloma is a small growth inside a milk duct. Duct ectasia means that a duct has become widened and may collect thicker fluid. The two findings can occur near each other or be considered when the same symptoms are present, but one does not automatically mean the other. Discharge may be clear, yellow, greenish, or blood-stained. Tenderness or a small lump can also occur, while some people have no symptoms.

Arrange an examination if discharge, a lump, or a nipple change persists. Tell the clinician whether the discharge is spontaneous, which breast is affected, and whether you have pain, fever, or recent breastfeeding. Imaging can help show widened ducts or a growth. If the finding is not clear, a [Breast Biopsy](/treatments/diagnostics-and-imaging/breast-biopsy/) may examine tissue. Persistent symptoms or a localised problem may lead to discussion of [Breast Lump Excision](/treatments/breast-care/breast-lump-excision/).

Seek prompt review for discharge that appears without squeezing, especially if it is from one breast or blood-stained. A new lump, nipple inversion, skin dimpling, fever, spreading redness, or worsening pain also needs timely assessment. These signs can have benign explanations, but examination helps separate infection, duct changes, and other causes.

Ask whether the report describes duct ectasia, a papilloma, or both; what imaging shows; and whether sampling is needed. Ask how symptoms should be managed while waiting and when follow-up should occur.
