Patients who have breast cancer can choose breast conservation before their doctors will recommend breast conservation and recommend patients to use breast-conserving methods for treatment. If the patient has advanced breast cancer and cannot be breast conserved, breast conservation should not be forced because it may lead to residual tumor or tumor recurrence soon. If the patient’s mammary gland is removed, it will affect the patient’s life and may affect the patient’s physical and mental health. Therefore, if breast-conserving surgery is used for treatment, the appearance of the breast can be maintained after surgery, which means that the patient’s aesthetic appearance can be maintained. After breast-conserving surgery, you need to come to the hospital for regular review, including MRI review, etc.
