Diagnostic Test
Galactography
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.

Indications and Recommendations
- Spontaneous unilateral breast discharge
- Bloody or serosanguineous nipple discharge
- Suspected intraductal papilloma
- Evaluation of breast ductal tree lesions
Risks and Complications
- Pain or discomfort during catheter insertion
- Inability to catheterise the duct if there is no active discharge at the time of the test
- Allergic reaction to the iodinated contrast (uncommon)
- Infection (uncommon)
- Minor bleeding or spotting
- Low-dose radiation exposure
Frequently Asked Questions
What is galactography used for?
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.
Is galactography painful?
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.
When should I be concerned about nipple discharge?
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.
