If it is clear that the right duct is enlarged as a result of breast enlargement, whether it is serious or not depends largely on the degree of enlargement of the duct. If the ductal enlargement is mild, it is usually not very serious; if the ductal enlargement is severe, it is more serious and may require surgical treatment. 1. Mild enlargement of the right duct of breast hyperplasia: patients with mild enlargement of the right duct of breast hyperplasia do not have obvious clinical symptoms, and generally do not need to receive special treatment, and come to the hospital regularly for ultrasound review. 2. Severe enlargement of the right duct of mammary gland hyperplasia: if the right duct of mammary gland hyperplasia is severely enlarged, if the treatment is not timely, a localized lump may be formed, and accompanied by painful symptoms. Some patients may even form abscesses that may break out and need to cooperate with doctors to undergo surgery. The severity of the disease varies from patient to patient. It is recommended that patients with enlarged right duct go to the breast surgery department of a hospital and receive treatment under the guidance of a specialized doctor.
