Which symptom is related to mammary duct ectasia?

Mammary duct ectasia is a condition characterized by the dilation and inflammation of ducts beneath the nipple, which can lead to a blockage. One of the key symptoms associated with this condition is the presentation of thick, sticky dark green fluid leaking from the nipple. This discharge is a result of the accumulation of fluid and debris within the dilated duct, often leading to infection or inflammation.

The nature of the fluid and its color can be significant diagnostic indicators. In the context of mammary duct ectasia, the discharge is typically thick and can be dark green or even black, which distinguishes it from other conditions that may cause nipple discharge. This symptom is particularly associated with the obstruction and subsequent changes in the ducts of the mammary system.

Understanding this connection helps in recognizing the condition early and seeking appropriate medical attention. The other symptoms listed, while they may relate to different breast conditions, do not specifically correspond to mammary duct ectasia in the same way.
