Summary
Brief summary (as posted)
* The surgical method for breast cancer is determined according to the size and location of the remaining lesions after prior chemotherapy. * There are many patients who were able to undergo partial resection when confirming the final results of patients who underwent total resection after prior chemotherapy. * Therefore, we would like to investigate whether it is effective to make decisions based on the results of pre-operative tests after prior chemotherapy.

Inclusion Criteria: * Breast cancer patients over 20 years of age undergoing surgery at Seoul National University Hospital * Patients to undergo total mastectomy * Patients who received neoadjuvant chemotherapy and undergoing total mastectomy were the main subjects, but as a control group, patients who did not receive neoadjuvant chemotherapy but undergoing total mastectomy were included as subjects. Exclusion Criteria: * In case of total mastectomy at the request of the patient * Except for cases where total resection is performed regardless of size because it is a lesion under the areola and is close to the nipple.
