Chemotherapy is a relatively common method of anti-tumor treatment. Generally the cost of chemotherapy varies for different periods or with different drugs. For different tumors, the chemotherapy drugs used are different and the duration of the course of treatment is different. A course of chemotherapy may cost about 6000-8000 RMB. For example, post-operative adjuvant chemotherapy for malignant tumors of the stomach and intestines may cost about 5600 RMB for one course of treatment. If it is palliative chemotherapy for advanced tumors, the course of treatment is longer and a course of treatment may cost about 6400 RMB. For lung cancer, the cost of chemotherapy is higher, and a course of chemotherapy may cost about RMB 8800. Of course, the cost varies from region to region, from hospital to hospital, or from imported drugs to domestic drugs. Some patients have longer hospitalization time and more reactions to chemotherapy, so the cost is also higher.
