The cost of a lymph node biopsy is 500-1000 yuan, but of course the price may vary from hospital to hospital. Large tertiary hospitals may cost more; if small hospitals, such as county hospitals or township health centers, the cost may be slightly cheaper. Lymph node biopsy surgery is a minor procedure that can be performed in an outpatient operating room, usually under local anesthesia. In other words, after disinfecting the skin twice with iodophor, infiltrating anesthesia with lidocaine under the skin, cutting the skin surface after the anesthesia is effective, bluntly separating it, and then sending the lymph nodes for pathological examination after complete removal. After the wound is hemostatic, the wound is sewn up with sutures and the sutures are removed at the right time.
