What does it mean for a woman to lose her breasts? According to relevant surveys, the average age of patients who have had their breasts removed due to breast cancer is only 52 years old, and 90% of them have completely lost their sexual life, and more than 70% of them have various psychological problems. So for patients, such questions are very, very important. Female friends' understanding of breast cancer, many people think that the more excision, the cleaner it is, and only in this way can we "save our lives". In fact, with the emergence of early diagnosis methods of breast cancer and the maturity of breast-conserving treatment technology and postoperative comprehensive treatment, some patients with early breast cancer can choose to keep most of their breasts and basically maintain their appearance on the premise of complete tumor resection. Compared with the traditional radical mastectomy, breast-conserving therapy not only preserves the breast, improves the quality of life, but also improves the function of the affected upper limb, reduces the surgical complications, and can obtain the same long-term survival rate as the improved radical mastectomy. However, the awareness of breast-conserving surgery is still disappointing. Clinically, a 27-year-old female white-collar worker had her whole left breast removed two years ago because of breast cancer. According to her medical record, the doctor is fully qualified for breast-conserving treatment, but she has no choice because she doesn't know there is such a treatment. Relevant surveys show that 70% of women with breast cancer did not know that they had breast-conserving surgery before operation, including many white-collar women. The reason is that their experts say that doctors should fully respect patients' right to know and let patients who meet the conditions of breast-conserving treatment choose their own treatment methods. At the same time, patients should also enhance the awareness of "breast-conserving", eliminate the concept that "breast-conserving" treatment is not thorough, and make the best choice for their own treatment. Early treatment of breast cancer has good effect and high survival rate. There are many drugs used to treat early breast cancer in clinic, such as Ruiting (anastrozole tablets), which can be used as an adjuvant treatment for estrogen-positive early breast cancer in postmenopausal women. The prognosis of breast cancer is worse in the advanced stage. Similarly, "breast-conserving surgery" also requires patients to be in the early stage of breast cancer, the tumor size is no more than 3cm, the tumor site is more than 2cm away from the areola, and the best lesion is located around the breast, and no multiple lesions have been found by various means. Finally, intraoperative rapid frozen pathological examination confirmed that there were no cancer cells at the margin of the resection range.
