Lymphatic metastases can be treated with breast-conserving therapy, although it depends on the stage of the tumor and intraoperative lymph node dissection. Breast-conserving surgery has been carried out in China in recent years with the advancement of technology and people’s demand for beauty. The purpose of breast-conserving surgery for breast cancer is to remove the lump and preserve the breast. It is suitable for patients with clinical stage 1 or 2 breast cancer. If there is lymph node metastasis, lymph nodes need to be cleared. And radiotherapy is performed after surgery. But breast conservation requires conditions. The conditions include that the tumor is peripheral and there is no contraindication to radiotherapy. The treatment of early breast cancer patients not only improves the survival rate, but also aesthetic. Therefore, breast cancer patients should be diagnosed and treated as soon as it is detected.
