Breast cancer has the highest mortality rate among women worldwide, including in Thailand. Early diagnosis of breast cancer increases the patient’s chance of being cured. For cancer patients with metastasis, surgery combined with other treatments such as radiation therapy, chemotherapy, hormone therapy, targeted therapy and immunotherapy, is required. It increases the survival rate of patients to approximately 80 – 90%. This study is a retrospective analysis of 162 breast cancer patients at Maharaj Nakhon Si Thammarat Hospital, who underwent conventional modified radical mastectomy (MRM) with adjuvant therapy based on clinical indications. By studying the clinical and pathological characteristics of patients from January 1, 2014, to December 31, 2019. The 5-year survival rate for patients was found to be 66%. Patients with tumors smaller than 20 millimeters had the highest survival rate (85.7%), while the survival rate decreased as tumor size increased. It was also found that tumors larger than 40 millimeters had a metastasis rate to lymph nodes of over 80%. Therefore, breast cancer patients with tumors larger than 40 millimeters should undergo surgery using the MRM method.
