The breast not only has the physiological function of breastfeeding, but also has an important role in female form and cardiac flow, and the psychological role has an impact on the immune function of the body. Traditional radical breast cancer surgery includes the entire breast, the lymphatic fatty tissue of the axilla, and in some cases, the pectoralis minor or pectoralis major muscle. The total excision of the breast is not E a painful experience for a woman, and many women suffer a double blow physically and psychologically after surgery – their bodies are crippled and their families are broken. An informal survey conducted by the Shenzhen Cancer Association found that the divorce rate after total breast cancer excision is as high as 40%. And for many early breast cancer patients, this is all can be avoided. The essence of breast-conserving treatment for early-stage breast cancer patients, Zhang Gangling, Breast Surgery Department, Baotou Cancer Hospital, lies in the complete removal of tumor lesions while preserving satisfactory breast shape. Advantages of breast-conserving surgery Breast-conserving surgery means removing the tumor and part of the surrounding normal breast tissue, while performing axillary lymphatic and fatty tissue clearance, the scope of which is exactly the same as that of traditional radical surgery. Total mastectomy was formerly the mainstream procedure in developed countries in the West and in major cities such as Beijing and Shanghai in China, but has been gradually replaced by breast-conserving surgery in recent years. The biggest advantage of breast-conserving surgery is that the external form of the breast is basically preserved, therefore, the psychological impact on the patient is much less than that of total mastectomy, in addition, breast-conserving surgery is less traumatic and, in a sense, more suitable for elderly patients. Prognosis of breast-conserving surgery Breast-conserving surgery has been performed in hundreds of thousands of cases worldwide, and there have been nearly 10,000 large randomized controlled clinical trials, with the longest observation period having exceeded 20 years. Comprehensive trials have shown no difference in long-term survival between the two procedures. This means that the long-term survival of breast-conserving treatment is equivalent to that of total mastectomy. The “beauty” of breast-conserving surgery does not come at the expense of life. Breast-conserving surgery is not available to all breast cancer patients. It has strict surgical indications and the initiation of breast-conserving procedures is contingent on the patient’s clear desire to preserve the breast; it should also be emphasized that radiation therapy after breast-conserving surgery is an integral part of breast-conserving treatment. For patients who are unable to complete breast-conserving surgery, we also offer the option of reconstructive breast reconstruction with stage I shaping. Breast-conserving surgery has now surpassed total mastectomy as the most used surgical procedure in Western developed countries. In China, it is mainly concentrated in specialized hospitals in some major cities. Our department was the first to perform breast-conserving surgery in Inner Mongolia Autonomous Region, with nearly 400 patients from 2001 to the present, and no local recurrence cases have been found. The use of extensive local excision and post-operative radiotherapy can avoid the “destruction” of the breast and thus meet the desire of breast cancer patients to cure the disease while preserving the aesthetic shape of the breast.
