Multiple cysts in the breast are caused by the formation of cysts due to necrosis of the milk ducts, both simple and caused by accumulation of milk. The specific treatment methods are as follows: 1. It is important to maintain good living habits, reasonable diet structure, less spicy and stimulating food, more high-protein, high-fiber food, work and rest, appropriate exercise, and control of stable emotions. 2. Regular observation, no obvious symptoms can first not do the relevant treatment, regular review once every six months to review the ultrasound. If there are changes in the condition, such as irregular cysts like burrs and many calcified spots, they need to be checked for benign and malignant. 3. Surgery, if the cysts seriously affect their lives or have a high probability of malignant change, they need to be removed in stages by minimally invasive surgery. After surgery, regular review is also needed and should not be taken lightly.
