Minimally invasive breast surgery is generally suitable for lumps <3cm in diameter. 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 injury and faster recovery. In addition, after minimally invasive surgery, it is usually necessary to press the minimally invasive site with hand pressure for half an hour to stop bleeding, and it is also necessary to use cotton pads or elastic bandages for three consecutive days to observe whether there is any bleeding, hematoma and other situations. There is usually no scarring after surgery.
