Diagnostic Test
Description
Galactography is a radiological study that visualises in detail the galactophorous ducts (milk ducts) by injecting iodinated contrast directly into the duct from which the discharge comes. It is the reference technique for evaluating abnormal breast discharge, especially unilateral or bloody nipple discharge, and for detecting intraductal papillomas and other ductal tree lesions.
Practical Information
20-30 minutes
Do not squeeze or manipulate the nipple before the test to preserve active discharge. Do not apply creams or deodorant in the area on the day of the test. If the discharge has stopped, notify the centre before attending.

Frequently Asked Questions
Galactography allows visualisation of the interior of the breast ducts when there is abnormal nipple discharge. Its main purpose is to detect or rule out intraductal papillomas (small benign duct tumours) and other lesions that may cause the discharge.
Most patients report that galactography is uncomfortable but not painful. A small catheter is inserted into the duct opening that is discharging, which may cause a brief feeling of pressure. The procedure takes 20-30 minutes.
You should always consult when discharge is: spontaneous (without pressing), unilateral (from one breast only), from a single nipple opening, bloody or clear serous in colour. Bilateral milky discharge usually has a hormonal cause and rarely requires galactography.
