Liver tumors include benign tumors and malignant tumors, benign tumors such as hepatic hemangioma and hepatic adenoma, and malignant tumors such as hepatocellular carcinoma and hepatic sarcoma. For benign tumors and early malignant tumors, there is a possibility of cure, but it is less likely to be cured by interventional therapy alone; for middle and late stage liver malignant tumors, it is basically incurable by interventional therapy alone, but the condition can be stabilized and the survival time can be prolonged by interventional therapy. For early stage small tumors, the blood vessels of tumors can be blocked through interventional therapy, and then chemotherapy drugs can be injected into the tumors to inhibit the growth of tumors and kill the tumor cells to a certain extent, thus achieving the purpose of controlling the disease. However, tumor cells may also have other blood vessel supply and can stimulate the formation of new blood vessels by themselves, so interventional therapy alone cannot completely kill tumor cells, and comprehensive treatment is needed to control the disease. Doctors will usually choose the appropriate treatment plan according to the patient’s specific condition and tolerance level to improve the condition and enhance the patient’s quality of life and survival time. To enhance the efficacy of treatment, it is usually necessary to combine other treatment modalities, such as radiotherapy, chemotherapy, Chinese medicine and physical therapy such as laser, freezing and microwave, as well as targeted immunotherapy, antiviral and hepatoprotective drugs. In addition, since interventional treatment is invasive, adverse reactions such as epigastric pain, abdominal distension, nausea, vomiting and fever may occur, and if the symptoms are severe, they can be reported to the doctor in time and appropriate treatment measures can be taken. During the treatment period, we should pay attention to rest, keep the local wound clean and dry, as well as relaxation, which is beneficial to the recovery of the disease.
