A galactogram is a test that uses a dye to make a picture of the milk ducts in the breast. This test may be done when there is discharge that leaks from the nipple, especially when the discharge has blood.
A very small tube is threaded into the milk duct. Dye is put in and then mammogram pictures are taken. This makes a map-like picture of the milk ducts. The doctor can then look for the cause of the discharge.
What can I expect?
- The test takes about 20 minutes.
- The test may be uncomfortable for some women.
How can I prepare?
- You may eat or drink ahead of time.
- You will be asked to undress from the waist up. It may be easier to wear a two-piece outfit.
- Do not squeeze fluid from the nipple for several days before the test.
