There is no such thing as “which is better, breast conservation or total mastectomy”. The choice of surgical method is generally based on the doctor’s assessment and the patient’s wishes. 1. Doctor’s assessment: If the woman has a low grade malignant tumor, no extensive granular calcification, a single tumor, the tumor is in a suitable position from the areola, and the diameter of the tumor is less than three centimeters, it is generally suitable for breast-conserving surgery. If they are older, have extensive lesions, breast tuberculosis, advanced breast cancer, etc., it is just necessary to do total mastectomy. 2. Patient’s wish: If a woman is not willing to undergo total mastectomy, or if she still needs to breastfeed, she can consider breast-conserving surgery. If a woman chooses to have total mastectomy, she can also choose to have total mastectomy according to her condition. To sum up, it is recommended that patients with breast tumors should consult the doctor in time, strictly follow the doctor’s instructions, and choose the appropriate surgical method for treatment.
