The specific department for chemotherapy depends on the patient’s disease. For example, if the patient has acute lymphoblastic leukemia or acute myeloid leukemia, lymphoma, etc., the patient can register for hematology. If the patient is suffering from solid tumor, such as breast cancer, lung cancer, stomach cancer, etc., if the patient needs chemotherapy, the patient will be registered with medical oncology. If some hospitals have subspecialties of medical oncology, they can register breast medicine, gastrointestinal oncology, thoracic medicine and the corresponding internal medicine department for chemotherapy. If the time of chemotherapy is short, for example, chemotherapy can be completed in a single day, the patient can register with the day chemotherapy department of oncology hospital.
