Regarding the question of whether breast cancer can be cured, it can be clearly said that most primary breast cancers can be cured if there is no recurrence or metastasis within 5 years after standard surgical treatment, chemotherapy, radiotherapy, endocrine therapy, targeted drugs, etc. In recent years, there are many news about breast cancer, such as “famous singer died of breast cancer” and “Hollywood movie star had her breast tissues removed to prevent breast cancer”, etc., which constantly provoke people’s sensitivity. “In fact, it is not necessary to be afraid of breast cancer. In fact, it is not necessary. Breast cancer can be cured as long as regular medical checkups, prevention, early detection and early treatment are carried out. For patients who have been treated for breast cancer, the most worrying thing is the recurrence. After determining the recurrence of breast cancer, patients need to determine the status of recurrence – whether it is only in the breast where the tumor grew, or in the other side of the breast, or in the lymph nodes or even in the liver or lungs. After determining the status of recurrence, biopsy of the recurring tumor is needed to determine the diagnosis and staging, and finally the doctor will make the next treatment plan based on these test results. Can breast cancer be treated by surgery again after recurrence? This depends on the situation. If the recurrence is only in the breast or local soft tissues and no cancer lesions are found in other parts of the body, surgery is preferred if complete excision is possible; if there is metastasis or recurrence in the organs, surgery may not be preferred. Patients with recurrence or metastasis often need systemic drug treatment, whether it is chemotherapy or endocrine therapy or targeted therapy, which requires comprehensive judgment by doctors. The purpose of chemotherapy after recurrence is different from that of chemotherapy after the first surgery. Chemotherapy after the first surgery is called “adjuvant chemotherapy”, which aims to completely cure breast cancer; chemotherapy after recurrence is called “rescue chemotherapy”, which can’t cure breast cancer yet, but can control the development of the disease and prolong the patient’s survival. However, it can control the progression of the disease and prolong the survival time of patients. Regarding the effect of treatment after recurrence, doctors need to know whether the tumor staging has changed, the time interval between the first treatment and the first treatment (the longer interval, the less malignant the tumor may be), and the sensitivity of the tumor to the treatment during the first treatment, etc. The effect of treatment varies from patient to patient.
