Clinically there is no most effective way to make breasts bigger and smaller. Big breasts are usually caused by excessive localized fat or well-developed mammary glands, and patients can go to regular hospitals to make breasts smaller through liposuction and breast reduction surgery. 1. Liposuction: Liposuction surgery is minimally invasive, a small opening is made in the hidden part of the chest, and the fat in the breast is sucked out evenly with a fat suction tube. Through liposuction of the breasts, the effect of making the breasts smaller can be achieved in a short period of time. 2. Breast Reduction Surgery: Patients can remove the excess fat and glands from the breasts through breast reduction surgery, and the nipples can be moved upward to achieve the effect of binding the breasts. This method is suitable for patients with large bilateral breasts, serious sagging and the impact on life. Patients who want to make their large breasts smaller can choose to go to a regular hospital to be operated by a professional doctor, pay attention to the wound area to prevent infection after the operation, and go to the hospital immediately if discomfort occurs.
