What is Mammary Duct Ectasia?

Mammary duct ectasia is a benign breast condition in which the ducts beneath the nipple become widened (dilated) and filled with fluid. This enlargement can lead to inflammation, blockage, and sometimes infection. Although it can occur in women of any age, it is more common in middle-aged and older women, particularly those who are nearing menopause. Mammary duct ectasia is usually non-cancerous, but its symptoms can mimic other breast conditions, making accurate diagnosis important.

The condition may develop slowly over time and often affects multiple ducts. The dilation and fluid accumulation can irritate surrounding breast tissue, causing discomfort or changes in the nipple area. While it is generally not serious, patients experiencing persistent symptoms should consult a healthcare provider to rule out more serious conditions such as breast infections or malignancies.

Symptoms

The primary symptoms of mammary duct ectasia include nipple discharge, which may be thick, sticky, or greenish, and sometimes bloody. Patients may notice tenderness or a burning sensation around the nipple, and occasionally, the nipple may invert or become retracted. Swelling of the ducts can also cause palpable lumps near the nipple area, which may be concerning to the patient.

In addition, some women experience redness, warmth, or mild pain in the affected breast, especially if inflammation or secondary infection occurs. While mammary duct ectasia is usually painless, any changes in breast shape, persistent pain, or unusual discharge should prompt a clinical evaluation to ensure the condition is correctly identified and managed.

Causes

The exact cause of mammary duct ectasia is not fully understood, but it is believed to be associated with aging and hormonal changes, particularly around menopause. As ducts lose elasticity and become dilated, they may fill with fluid and cellular debris, leading to inflammation. Smoking has also been identified as a contributing factor, as it can increase the risk of ductal inflammation and nipple retraction.

Other potential contributing factors include past breast infections, trauma, or blockages in the ducts. The combination of duct dilation, fluid accumulation, and chronic inflammation can lead to the characteristic symptoms of nipple discharge, tenderness, and occasional lump formation.

Treatment

Treatment for mammary duct ectasia depends on the severity of symptoms. Mild cases may not require any intervention, and patients can manage discomfort with warm compresses or over-the-counter pain medications. For cases with recurrent infection or significant inflammation, antibiotics may be prescribed to treat or prevent bacterial involvement.

In persistent or severe cases, surgical options such as microdochectomy (removal of the affected duct) or more extensive duct excision may be considered. Surgery typically resolves symptoms and prevents further complications. Patients are advised to maintain regular breast examinations and consult a healthcare professional if new symptoms develop to ensure early detection and treatment.
