1.Radiofrequency ablation treatment for tumor, as the saying goes, is to “burn” the tumor, which kills the tumor and the cells around the tumor by high temperature. 2, anhydrous alcohol injection therapy for tumor, to use alcohol to chemically harm the tumor, especially in patients with tumor next to blood vessels, bile ducts and other structures easily damaged by ablation but cannot be left untreated, there are pancreatic tumor patients with very obvious pain, ultrasound suggests enlarged retroperitoneal lymph nodes, consider metastatic cancer, but close to large blood vessels, deeper in not easy to perform radiofrequency ablation, the use of alcohol effect Some of them are very good, and the pain is obviously relieved or even not painful after surgery, but of course, how long the pain is not painful depends on the patient’s tumor progress speed, but there are indeed patients with very good effect. 3, benign tumor hypertonic sugar water occlusion sclerosis, generally for cysts, the use of hypertonic sugar water on the cyst wall cells to kill, so that after the cyst fluid extraction cysts no longer have cyst wall cells secrete cyst fluid resulting in cyst recurrence, of course, the effect of this treatment depends on the cyst is big or not, large cysts recurrence chance will be relatively high. These methods are more common, wait until you have time to talk to you about these methods before and after surgery need to pay attention to it.
