Liver cancer is one of the common malignant tumors. The development of liver cancer is closely related to chronic hepatitis (hepatitis B), and also related to aflatoxin, nitrosamines, parasitic infections, environmental pollution, genetic factors and so on. The symptoms of liver cancer can be manifested as: swelling and pain in liver area, enlargement of liver, loss of appetite, nausea, vomiting, jaundice, wasting, etc. Common treatment methods of liver cancer include surgery, radiotherapy and traditional Chinese medicine. The early symptoms of liver cancer are not obvious, and usually patients and friends with liver cancer are found in the middle and late stages of liver cancer. At present, interventional therapy has become the first choice for the treatment of middle and late stage liver cancer (especially for patients who have lost the chance of surgery) with its minimally invasive and high efficiency, and has been well received by patients and friends. Interventional treatment for liver cancer has the following advantages: 1. It is simple and easy to operate, safe and reliable. The skin incision is only about 2mm, which is less painful for patients. It can be performed especially for the old and frail patients and those with certain diseases, without general anesthesia, and the patient remains awake during the whole treatment. 2.Effective treatment. It can deal with multiple or recurring tumor nodules in stages, multiple times and repeatedly according to the condition and treatment needs; successful treatment can see rapid decrease of AFP, shrinkage of tumor mass and pain relief. Interventional treatment for advanced liver cancer can achieve precise location and accurate treatment, directly cut off the blood supply of tumor and “starve” the tumor cells, with little damage to normal tissues. 4. Interventional treatment of liver cancer is under the monitoring of modern imaging equipment (DSA), which can accurately evaluate the efficacy in real time. 5.Fast recovery: usually normal activities can be performed 24 hours after surgery; for some liver cancers, they can be resected in two steps after volume reduction. 6.The survival period of patients with intermediate and advanced hepatocellular carcinoma is significantly prolonged and the quality of life is significantly improved after interventional treatment.
