Breast cystic masses are breast cysts, usually multiple, and the masses are finely dotted usually benign lesions, usually not serious. Breast cysts are produced by the retention of mammary secretions in the ductal tissues, and the breast epithelial cells at the lesion site have obvious parietal secretion, which is due to endocrine disorders caused by ductal epithelial hyperplasia, increased cells in the duct, resulting in ductal extension and tortuous, and necrosis occurs in the anterior wall at the fold due to ischemia, resulting in the formation of cysts. Breast cystic mass fine point belongs to a relatively small cyst, if there is no obvious symptoms, then no treatment, generally is not serious. If the breast cystic mass is large and accompanied by obvious symptoms, such as breast pain, surgical removal is required. It is recommended that patients with breast cystic masses in the form of fine dots should go to the hospital regularly for breast ultrasound review to observe the size of the cysts and other symptoms before choosing an appropriate treatment plan.
