Firstly, a group of experienced experts including breast surgery, radiotherapy, chemotherapy, targeted therapy and Chinese medicine oncologists should be consulted and discussed before treatment to develop a detailed, complete, systematic and scientific treatment plan. Second, the treatment plan should be completed. Surgery, radiotherapy, chemotherapy, immunotherapy and targeted therapy are commonly used as effective approaches, but no single treatment method alone can guarantee a cure; most of them require comprehensive treatment. For example, for breast cancer patients who undergo breast-conserving surgery, not only radiotherapy but also chemotherapy, endocrine therapy or targeted therapy should be performed after surgery according to the pathology and immunohistochemistry, which is an important means to prevent tumor recurrence and metastasis, and also an important reason to do radiotherapy after surgery. Post-operative radiotherapy can greatly reduce the recurrence rate and improve the survival rate. Thirdly, regular review should be done after treatment. Breast cancer patients may have recurrence and metastasis at any stage after any treatment. Timely, careful and regular check-ups are likely to detect metastasis and recurrence at an early stage so that early measures can be taken to deal with them and prevent further deterioration of the disease. The review includes self-examination by the patient and regular examination by the hospital. The main purpose of self-examination is to observe whether there are any new swellings, nodules, ruptures, etc. in and around the original lesion site, and whether there are new painful sensations; in addition, we should pay attention to the systemic changes, whether there are gradually increasing weakness, loss of appetite, weight loss, anemia, etc. Once the above situation occurs, we should go to the hospital for examination. Fourth, to maintain an optimistic state of mind, strengthen nutrition and physical exercise. Research proves that optimistic attitude, good nutrition and proper physical exercise are conducive to keeping the immune function in the best condition, giving full play to anti-cancer activity, accelerating recovery and preventing recurrence. For breast cancer patients, family members should give more care to them, especially spouses should communicate more with them and should not be cold or discriminate against them. Breast cancer patients can also participate in mutual support alliances among patients to share their confusion and seek help.
