Traditionally, it is believed that breast cancer can only be cured by cutting off the entire mammary gland. However, a recent authoritative clinical trial from abroad has confirmed that breast-conserving surgery patients have a longer survival time than traditional radical mastectomy! The traditional breast-conserving technique requires that “the tumor is less than 2 centimeters, 3 centimeters away from the nipple, and the lymph nodes are negative, etc.”, but in recent years, the international emerging so-called “oncoplastic” technique has greatly widened the indications for breast cancer that can be breast-conserved. In the traditional breast cancer breast-conserving technique, some breast-conserving patients, especially those in the upper outer quadrant, have a good shape after breast conservation, but most of them have an unattractive breast shape after breast-conserving surgery, and the deformity is very obvious, which can not guarantee a beautiful breast shape. With breast cancer, most patients and their families are overly nervous, resulting in the removal of breasts that should not have been cut, however, the hasty decision leads to the patient’s lack of self-confidence for the rest of her life! Psychological stress! Self-perception of not being able to hold up one’s head in a crowd. Under the premise of not violating the principle of tumor-free and not affecting the patient’s survival time, we hope that patients and their families can choose rationally!
