Tumor will be necrotic after liver cancer intervention. After liver cancer intervention, arterial blood supply of tumor can be blocked, resulting in ischemic necrosis and shedding of tumor. However, some liver cancer patients appear to have tumor necrosis after intervention therapy, but it cannot be completely excluded that there is residual blood supply in the tumor lesion, or some incompletely necrotic tumor cells release pro-angiogenic factors to activate vascular endothelial cells, and the tumor may continue to grow after a period of time or years. Therefore, tumor necrosis after interventional therapy for hepatocellular carcinoma does not mean that it can be solved once and for all. It is recommended that patients should go to the hospital for regular review and follow-up to observe whether there is any change in the blood supply of the tumor as well as whether the tumor lesion has the tendency to continue to grow, etc. Once any abnormality is detected, they should cooperate with the professional doctors to take effective therapeutic measures in time to control the condition as early as possible.
