1. Chemotherapy: Chemotherapeutic drugs can be injected into patients' veins and then transported to the whole body through the heart, so that cancer cells can be killed and treated.
2. Radiotherapy: Radiotherapy mainly uses positioning to irradiate radiation to the position of tumor, thus killing some tumor cells.
3. Targeted therapy: Targeted therapy is a relatively new treatment method at present. Before treatment, it is necessary to do genetic examination to confirm whether the patient has genetic mutation, and then choose appropriate targeted drugs for treatment. Treating patients in this way can prolong their lives.
