Surgery is recommended for breast tumors after a clear diagnosis, regardless of whether it is 1cm or 2cm. Of course, the smaller the tumor, the earlier the stage of the tumor, the faster the patient recovers after surgery, and the 5-year survival rate is very high after surgery. If the tumor is benign, it is better to do the surgery when it is small, because the tumor is small and can be operated by minimally invasive surgery, that is, tumor rotation surgery, which is less traumatic after the surgery, and there is basically no wound on the surface of the breast and no scar after the surgery.
