Nipple discharge means any fluid that comes out of a breast nipple.
Nipple discharge during pregnancy and breast-feeding is typical. At other times, it may not be cause for worry. But it's good to have a healthcare professional examine your breasts if the nipple discharge is a new symptom. Men who ever have nipple discharge should have a medical exam.
Discharge can come from one or both breasts nipples. It might happen from squeezing the nipples or breasts. Or it might happen on its own, called spontaneous. The discharge comes through one or more of the ducts that carry milk.
The fluid might look milky, clear, yellow, green, brown, gray or bloody. It can be thin and sticky or thin and watery.
