Mammary Duct Ectasia

What it is

Mammary duct ectasia is when a milk duct under your nipple gets wider and thicker. This can cause the duct to get blocked with fluid, leading to swelling and irritation in the area. It is a benign, meaning not harmful, condition.

How common it is

This condition is most common in women who are getting close to or are in menopause, usually in their 40s and 50s.

What you may notice

You might notice a thick, sticky nipple discharge that can be green, black, or another color. You could also feel a small, tender lump right behind your nipple, or the nipple may start to pull inward.

What can contribute

The natural changes in your breasts as you approach menopause are the main cause. Smoking is also known to be a strong risk factor for this condition.

How it is usually checked

Your provider will likely do a physical exam of your breast. To get a closer look, they may suggest imaging like a mammogram or an ultrasound to see what is happening inside the duct. In some cases, they may check a sample of the discharge.

Does this change my long-term risk?

Duct ectasia does not change your long-term breast health risk. It's important to get checked because its symptoms can look like other issues that need attention.

Comfort and everyday care

• Applying a warm, moist cloth to the nipple area may help soothe discomfort.
• Wearing a soft, supportive bra can help reduce tenderness.
• Some women wear soft breast pads inside their bra to absorb any discharge.
• If you smoke, working toward quitting is one of the best things you can do to help your body manage this condition.
