Liver metastasis means metastasis of cancer cells to the liver, which is usually caused by the patient’s own malignant tumor disease, and the condition is more serious, and the cancer cells have metastasized to the liver. Liver metastasis is a relatively common clinical condition, which can occur in malignant tumors in all organs of the body, and is commonly found in cancers of the digestive system such as stomach cancer and pancreatic cancer. When cancer cells metastasize to the liver, it is called cancer cell liver metastasis. The tumor caused by liver metastasis of cancer cells is called liver metastatic cancer. The difference between liver metastatic cancer and primary liver cancer is that patients usually do not have hepatitis, cirrhosis and other underlying diseases in the liver area, but the clinical symptoms of liver metastatic cancer are basically the same as those of primary liver cancer. In early stage, patients often have symptoms such as abdominal distension, loss of appetite, etc. With the increase of metastatic cancer volume, patients will also have symptoms such as right upper abdominal pain, nausea and vomiting, jaundice, ascites, etc. In conclusion, liver metastasis is a kind of liver cancer. To summarize, liver metastasis is a more serious condition, which usually indicates that the primary cancer in the patient’s body is in a more serious condition and is already in an advanced stage, so it is recommended that the patient should seek medical treatment as soon as possible to avoid delaying the condition.
