What to do if liver cancer metastasizes into the liver

Intrahepatic metastasis of liver cancer may include hematogenous metastasis and lymphatic metastasis, and may also cause symptoms of bloody ascites or pleural effusion. The prevention of this disease must be taken seriously. We must pay attention to preventing hepatitis and supplementing trace elements with a scientific diet.

1. Intrahepatic metastasis

(I) Liver cancer first metastasizes into the liver, where it can easily invade the portal vein and its branches and form tumor thrombi, which can then break off and cause multiple metastatic lesions in the liver. If the portal vein trunk is blocked by tumor thrombus, it may cause or aggravate the original portal hypertension.

(ii) Extrahepatic metastasis ① Hematogenous metastasis, with the highest rate of pulmonary metastasis, is caused by the tumor thrombus in the hepatic vein extending to the inferior vena cava, through the right heart to the pulmonary artery, forming metastatic lesions in the lungs. Hematogenous metastasis can also cause metastasis to the chest, adrenal glands, kidneys, bones, etc. ② Lymphatic metastasis. Local metastasis to the hilar lymph nodes is the most common, and it can also metastasize to the pancreatic, splenic, para-aortic and supraclavicular lymph nodes. ③ Implantation metastasis is rare and may occasionally be implanted in the peritoneum, diaphragm, chest cavity, etc. It causes bloody ascites and pleural effusion, and women may form large cancer masses in their ovaries.

2. Prevention of Liver Cancer

Since the main causes of liver cancer in my country are hepatitis, aflatoxin and drinking water pollution, many medical scholars believe that the strategy for liver cancer prevention should be "improving water, controlling food and preventing hepatitis."

1. Water improvement: The purpose of water improvement is to reduce drinking water pollution, and it is a measure that is likely to take effect in a relatively short period of time. The water improvement mainly transforms stagnant water into running water, and changes drinking pond water and house ditch water into drinking water, deep well water and tap water. Cities have switched to using less polluted water sources as tap water and encouraged the use of medicinal charcoal water purifiers. The water improvement has reduced the incidence of liver cancer in some areas.

2. Grain management: The focus of grain management is peanuts and corn, which are prone to produce aflatoxin. Mildew prevention mainly includes mildew prevention and detoxification of corn and peanuts, such as moisture-proof and mildew-proof from harvesting to storage and the treatment of moldy grains; screening of resistant varieties, that is, those that are not easily contaminated by mold; storage should be dry and ventilated and monitored regularly to control the moisture content of grains below 10%; and avoid eating moldy food.

3. Hepatitis prevention: Among liver cancer patients in my country, the hepatitis B virus infection rate is much higher than that of other viral hepatitis, so the main focus in my country is on preventing hepatitis B. Get hepatitis B vaccine in time and strictly screen blood donors.

The prevention of liver cancer starts with the cause. Other preventive measures for liver cancer include: quitting drinking, reducing pollution from organic farming and other pesticides, and supplementing trace elements such as selenium; selenium has the effects of inducing differentiation and inhibiting proliferation. In daily life, you can also eat some liver-protecting foods, such as mushrooms, cabbage, etc.
