Interruption of chemotherapy is not the same as doing it for nothing. Chemotherapy is an effective measure for treating tumors, but for some people, the side effects are relatively large and they have to interrupt chemotherapy, the common adverse reactions are hair loss, bone marrow suppression, vomiting and nausea, abnormal stools, rash and itching, etc. If the patient’s physique is weak and the adverse reactions are relatively serious, in this case, he should not continue chemotherapy. Treatment of tumor patients with chemotherapy interrupted for a period of time can continue to follow the standard treatment, if the body is still good, side effects are not very obvious, generally can continue chemotherapy. Patients should not use chemotherapy blindly under the guidance of physician’s consultation and in accordance with standardized chemotherapy, and if there is any discomfort during chemotherapy, they should reflect it to the attending physician in time to avoid delaying the condition.
