The cost of treatment for patients with low-risk leukemia ranges from a few tens of thousands to over a hundred thousand dollars; the cost of treatment for patients with medium- to high-risk leukemia with indications for transplantation ranges from roughly 300,000 to 1 million dollars. 1. If the patient is diagnosed with low-risk leukemia and does not need transplantation, and the symptoms can be relieved through regular review and chemotherapy and blood transfusion, the cost ranges from tens of thousands to over one hundred thousand dollars. Drugs include cytarabine and vincristine. 2. The treatment cost for leukemia patients with indication for transplantation is about 300,000~1,000,000 (before reimbursement by medical insurance), and the specific cost is related to the malignant degree of the patient’s disease, the degree of remission of the disease after chemotherapy, and the number of post-transplantation complications and their severity. The occurrence of leukemia is related to genetics, external biological, chemical, physical and environmental pollution, etc. Early stage of leukemia patients have fever, bone pain, local infection, fatigue and other symptoms. Early detection and early intervention can help prolong survival and reduce treatment costs. Specific treatment and medication should be carried out under the guidance of physicians.
