Does mammary duct ectasia require treatment?

The causes of mammary duct ectasia are complex, and it is a heterogeneous benign condition. Women aged 40–60 years constitute a high-risk group. The primary clinical manifestations include nipple discharge and subareolar masses. So, does mammary duct ectasia require treatment?

Does mammary duct ectasia require treatment?

Mammary duct ectasia is commonly encountered in clinical practice. Its underlying cause must first be clearly identified to determine whether treatment is necessary. If ductal ectasia results from a breast tumor—such as breast cancer or intraductal papilloma—treatment is required, primarily targeting the underlying neoplasm.

If ductal ectasia arises secondary to benign breast hyperplasia and the patient exhibits no significant clinical symptoms, regular follow-up examinations suffice, and no specific treatment is needed. However, if the patient develops mammary duct ectasia syndrome—a chronic autoimmune disorder—comprehensive management centered on surgical intervention is indicated, potentially supplemented by traditional Chinese medicine. Crucially, management of mammary duct ectasia hinges upon accurate identification of its etiology, which then guides the decision regarding treatment necessity.

Mammary duct ectasia syndrome—also known as plasma cell mastitis—is a chronic, non-bacterial inflammatory breast disease characterized histopathologically by ductal dilation and plasma cell infiltration. It predominantly occurs in non-lactating women. Particular attention should be paid when the following features are present: affected women aged 30–40 years, parous and non-lactating; deep subareolar mass with slow growth and recurrent episodes. Diagnostic evaluation may include breast ultrasound, mammography (X-ray with molybdenum target), breast CT, mammary ductoscopy, and histopathological examination of breast tissue.
