The breasts are made up of connective tissues that include a system of milk ducts — tiny passages that carry milk to the nipples. Mammary duct ectasia occurs when a milk duct beneath the nipple becomes dilated and filled with fluid. The milk duct can then become blocked or clogged with a thick, sticky substance. Mammary duct ectasia is not a sign of or a risk factor for breast cancer. However, it\'s always best to see your doctor if you aren\'t sure what\'s causing your symptoms. Mammary duct ectasia occurs most often in women in their 40s and 50s and affects as many as one in four women during or after menopause. It often causes no symptoms, but some women may have nipple discharge and breast tenderness.Mammary duct ectasia usually improves without treatment. However, if symptoms persist despite self-care measures, you may need surgery to remove the affected milk duct. Signs and symptoms Mammary duct ectasia is one of the most common causes of abnormal nipple discharge. Although it often doesn\'t cause signs and symptoms, some women may experience: A dirty white, greenish or black nipple discharge Tenderness in the nipple or surrounding breast tissue Redness lump or thickening An inverted nipple Possible causes include: Hormonal changes. Changes in your hormone levels may cause mammary duct ectasia. Smoking. Studies show that nicotine may have a toxic effect on your milk ducts Inverted nipple. Lack of vitamin A. Screening and diagnosis Mammary duct ectasia usually causes no symptoms. It may be found inadvertently on a mammogram or during a breast biopsy done for some other reason.you might need to have additional tests, which may include: Ultrasound. An ultrasound uses sound waves to make images of breast tissue. It allows your doctor to evaluate the milk ducts beneath your nipple. X-Ray. An X-ray of your breast can help your doctor find the cause of nipple discharge. Examination of nipple discharge. For this test, your doctor collects a sample of nipple fluid and sends it to a lab for analysis. Complications Complications of mammary duct ectasia are usually minor and often more bothersome than serious. These may include:Nipple discharge. Nipple discharge caused by mammary duct ectasia can be frustrating. Fluid leaking from your nipples can cause embarrassing wetness and staining on your clothes. Breast discomfort. Mammary duct ectasia can cause the tissue around your nipples to be red, swollen and tender. Infection. A bacterial infection such as mastitis may develop in the affected milk duct, sometimes causing you to feel ill and have a fever. Concern about breast cancer. You may worry about any changes in your breasts being a sign of breast cancer. Although mammary duct ectasia can sometimes cause scar tissue to form around the affected milk duct that feels like a hard lump, it\'s rarely linked to breast cancer. Treatment Mammary duct ectasia often improves without treatment. If your symptoms are bothersome, however, treatment options may include: Antibiotics. Your doctor may prescribe a 10- to 14-day course of antibiotics to treat any infection caused by mammary duct ectasia. Even if your symptoms greatly improve or disappear altogether, it\'s important to take the entire course of medication. While waiting for the antibiotics to take effect, take a mild pain reliever, such as acetaminophen (Tylenol, others) or ibuprofen (Advil, Motrin, others) as needed for breast discomfort. Surgery. If antibiotics and self-care methods don\'t work, the affected milk duct may be surgically removed. This procedure is done through a tiny incision at the edge of the colored tissue around your nipple (areola). However, surgery rarely is needed for mammary duct ectasia
