I hope that after reading this article, you will have a concept that breast cancer can be preserved and reconstructed, and that everyone needs a “personalized” surgery. I believe that when most patients learn that they have breast cancer, their first thought is whether they can save their lives. The second reaction is that most of the breasts will not be saved. In fact, in many cases, these two reactions are not reliable. The reliable ones are as follows: As medical pioneers continue to conduct in-depth research on various aspects of breast cancer, modern medicine has gradually transitioned from the purely physiological and pathological model in the past to a more social-psychological model. The surgical model and concept of breast cancer have also changed accordingly, from the previous emphasis on wide excision and local and regional radical treatment to the development of preserving the shape of the organ and minimizing damage, especially in recent years, excision plus repair and reconstruction have also flourished, and the treatment of breast cancer has changed from the previous single discipline to the integration of breast surgery, breast medicine, plastic surgery, pathology, diagnostic imaging, radiotherapy, etc. The treatment of breast cancer is developing in the direction of multidisciplinary collaboration. Nowadays, people’s health consciousness is gradually strengthened, and the general education of medical workers is in full swing, coupled with the annual health checkups of many units, the number of locally advanced breast cancers seen by breast surgeons has been significantly reduced compared to years ago. For most of the early stage and some of the intermediate stage, and even some of the locally advanced cases after the comprehensive treatment, breast-conserving surgery can be done under the premise that the patient wants to preserve the shape of the breast. Some patients are worried that their malignant tumors are not cleanly cut or they are not suitable for breast conservation after comprehensive evaluation, but they are worried about losing their breasts, and they have a high demand for their quality of life, and they want to return to self-confidence. The timing of reconstruction can be either Phase I reconstruction or Phase II reconstruction, what do you mean by Phase I and Phase II? What do I and II mean? The materials used for reconstruction can be prosthesis, prosthesis plus autologous tissue, or completely autologous tissue. Breast-conserving surgery is to preserve most of the affected breast while ensuring complete removal of the tumor, plus appropriate plastic repair techniques to ensure the aesthetic appearance of the affected breast. It is mainly for patients with breast-conserving intentions and no contraindications to breast conservation. It is suitable for patients with relatively early clinical stage, where the tumor volume is not too large and the breast has appropriate volume. It is also important to note that when breast-conserving surgery is performed, the surgeon may change the surgical approach to total mastectomy depending on the situation to ensure complete removal of the tumor within a safe range. Total mastectomy with breast reconstruction For some patients who do not want to preserve their breasts and are not suitable for breast conservation after comprehensive evaluation, total mastectomy can be followed by breast reconstruction, which has more psychological significance than physical significance at this stage. It means that the reconstructed breast has no function but only shape, which can improve the psychological trauma of losing the breast and allow patients to resume their normal social and life roles with more confidence. Perhaps in the near future, with the development of stem cells and bioengineering, the reconstructed breast will have both physiological and psychological functions. This is my wish, but it is very possible. Breast reconstruction after total mastectomy for breast cancer is divided into two types of surgical timing: Stage I reconstructed breast is reconstructed during total mastectomy and reconstructive surgery is performed during one anesthetic. Stage II reconstructive breast surgery is performed several months or years after total mastectomy. There are three general options for breast reconstruction and reconstruction materials for total mastectomy for breast cancer: 1. Artificial prosthetic implants. 2. Autologous tissue (various types of tissue flaps). 3. Autologous tissue combined with artificial prosthesis implants. Each of the three types of reconstruction materials has its own advantages and disadvantages, and each is suitable for different individuals. Conclusion: The treatment concept of modern breast cancer has changed significantly from the previous emphasis on surgical treatment to a multidisciplinary and comprehensive treatment. The concept of surgery has gradually shifted from the previous destructive radical surgery to “personalized” surgery for each individual, with more emphasis on the recovery of the patient’s psychological trauma when formulating the treatment plan. Therefore, when you know you have breast cancer, don’t be anxious, don’t talk about cancer, don’t get emotional, don’t listen to the wrong people, and don’t let the bullets fly for a while, to use a classic movie line. After your emotions are stabilized, you can participate in the treatment plan with your family members and ask your doctor for any personal opinions and requests about the treatment. I believe that every responsible breast surgeon will do his or her best to develop a treatment plan that best suits the individual needs of each patient. Please remember that “if you have breast cancer, you can keep your breast and you can make it”.
