How long one can live after chemotherapy is closely related to the physical quality of the individual and the clinical stage of the tumor, there is no clear survival time, it is recommended to cooperate with the doctor for active treatment. Common chemotherapeutic drugs in clinic include paclitaxel, vincristine, fluorouracil, cyclophosphamide, etc. Tumor patients with early stage of the disease and good physical quality can be significantly reduced or even cured after active chemotherapy, which has a relatively small impact on the life expectancy of the patients. If the tumor is in the middle or late stage and the patient’s physical quality is poor, chemotherapy can control the progress of the disease, improve the quality of the patient’s life and prolong the survival time of the patient. Therefore, the survival time after chemotherapy is closely related to many factors and cannot be accurately judged. It is recommended to actively cooperate with doctors to choose the most suitable chemotherapy drugs for treating the disease, and consult doctors in time when there is any adverse reaction, such as vomiting, rash, anemia, etc. Drug allergy is forbidden to be used.
