Some patients who have not received chemotherapy subjectively believe that chemotherapy has an effect on immunity, that it is difficult to tolerate the side effects of chemotherapy, and that it will aggravate the patient’s condition and accelerate disease progression. The fear of chemotherapy is far more than the fear of surgery, which is not right. Tumor is a systemic disease and chemotherapy is a very important systemic treatment, which is called the 3 major treatments for tumor together with surgery and radiotherapy. Chemotherapy is the abbreviation of drug chemotherapy. The treatment process for inpatients is actually no different from conventional infusion and oral drug treatment, which is done by intravenous infusion or oral drug, the biggest difference is the different drugs used compared with general infusion and oral drug treatment. Although the quality of life of patients will be affected during chemotherapy, patients will experience anorexia, nausea, vomiting, leukopenia, constipation, hair loss, etc., but in the long run, receiving chemotherapy can effectively control the growth of new lesions, prevent the formation of new metastatic lesions, and prolong the survival time of patients, which means that the survival benefits of patients after receiving chemotherapy far outweigh the adverse effects during the treatment, and this payment It is worthwhile. More importantly, oncologists will make individualized chemotherapy regimens according to patients’ specific conditions (chemotherapy regimens vary from person to person and will not be identical), apply drugs for early intervention to prevent chemotherapy-related adverse reactions, closely observe any adverse reactions and deal with them in a timely manner, so patients need not be afraid of chemotherapy and should actively cooperate with inpatient treatment.
