Chemotherapy may or may not be effective for cancer. Chemotherapy is effective for some cancers, but the effect needs to be combined with various factors such as the type of malignant tumor, stage, drug sensitivity, and patient’s physical condition. If the malignant tumor is of low malignancy, belongs to the early stage, is sensitive to chemotherapy, and the patient has good physical condition, chemotherapy is effective, on the contrary, the effect is not good. It is recommended to consult an oncologist. Among malignant tumors, leukemia, lymphoma and other hematologic diseases, some of them are sensitive to chemotherapy, and even can be cured by chemotherapy combined with bone marrow transplantation. Some solid malignant tumors, such as lung cancer, intestinal cancer, etc., are relatively ineffective to chemotherapy, while fibrosarcoma, smooth muscle tumor, etc. are even less effective to chemotherapy, but with the cooperation of the family members and the active treatment of the doctor, it is also possible to control the development of the disease, prolonging the patient’s life or improving the quality of life through chemotherapy. Fibrosarcoma, smooth muscle tumor, etc. are more effective to chemotherapy. If you suspect cancer, you need to consult a doctor and receive standardized treatment in time to avoid delay.
