The female breast contains tube-like structures called ducts. When a woman is breastfeeding, these ducts bring milk from the milk-producing glands to the area around the nipple. This allows the milk to flow from the breast to the infant.

A ductogram is a test to create images of the breast ducts. It is done with a mammogram and special contrast dye.

Possible Complications

Problems from the procedure are rare, but all procedures have some risk. Your doctor will review potential problems, like:

  • Adverse reaction to the contrast dye
  • Injury to the duct
  • Breast infection
  • Pain

Talk to your doctor about these risks before the procedure.
