Minimally invasive breast surgery is generally applicable to lumps with a diameter of <3cm. A small number of benign tumors with a diameter of 3cm or more, but in a good location, can also be considered for minimally invasive breast surgery. Minimally invasive breast surgery has the advantages of shorter operation time, less damage and faster recovery. In addition, after minimally invasive surgery, you usually need to press the minimally invasive site by hand for half an hour to compress and stop bleeding, and you also need to use cotton pad or elastic bandage to continuously apply pressure for three days to observe whether bleeding and hematoma occur. There is usually no scarring after surgery.
