Walking cannot cure cancer, but it can exercise the patient’s body and help cancer patients recover. The main treatments for cancer are surgical treatment, radiotherapy, chemotherapy and so on. 1. Surgical treatment: It is divided into preventive surgery, diagnostic surgery, radical surgery and palliative surgery. 2. Chemotherapy: some cancers can be cured by using chemotherapy alone (e.g. choriocarcinoma, malignant staphyloma, testicular spermatogonia, etc.), and there are also some tumors that can be relieved from symptoms for a long time by using chemotherapy (e.g. some leukemias, Hodgkin’s lymphoma, etc.). Commonly used chemotherapeutic drugs include cytotoxic drugs (e.g. cyclophosphamide, azide), antimetabolites (e.g. fluorouracil, methotrexate), antibiotics (e.g. adriamycin, paxillomycin), alkaloids (e.g. paclitaxel), molecularly-targeted drugs (e.g. imatinib), and so on. 3. Radiotherapy: tumors suitable for radiotherapy such as lymphohematopoietic system tumors, gonadotrophic adenomas, nasopharyngeal carcinoma, cervical cancer, cervical esophageal carcinoma, middle ear carcinoma and so on. Commonly used radiotherapy techniques include teletherapy, brachytherapy, intensity-modulated radiotherapy and so on.
