The treatment of breast cancer is different at different times, and not all breast cancer patients need to have their breasts removed. For patients with early detection and treatment of breast cancer, with the development of modern medical science, there is now a technique called “breast-conserving surgery”, which can realize the wishes of many patients who do not want to have all their breasts removed, and the post-operative results are very good, and the long-term prognosis is the same as that of breast removal. Some patients who cannot have breast-conserving surgery can also undergo breast reconstruction, which is basically the same as their own breast except that it does not have the function of breastfeeding. The long-term treatment effect of breast cancer is very good. 75% of breast cancer patients can be cured clinically and usually there is no recurrence or metastasis.
