What are the signals of liver cancer? What are the causes of liver cancer?

Early signs of liver cancer are rare in clinic, or there is no early warning sign of liver cancer. Most early liver cancer is found in regular physical examination. The so-called early liver cancer means that a single tumor does not exceed 5cm, or the number of tumors does not exceed 3, and the diameter of each tumor does not exceed 3cm. This condition can be removed by surgery and may be cured. Liver cancer is mostly formed on the basis of chronic liver disease, so if you want to find liver cancer early, you must strengthen regular physical examination. Patients with chronic liver disease, including viral hepatitis, long-term drinking, severe fatty liver, family history of liver cancer or unexplained cirrhosis, are all high-risk groups. Only through regular screening of high-risk groups can early liver cancer be found.

If liver cancer has obvious symptoms such as pain, abdominal mass, jaundice and fatigue, it often means that the tumor has entered the advanced stage. Of course, some patients with small liver cancer or early liver cancer go to the hospital because of the clinical symptoms of chronic liver disease and cirrhosis. Imaging examination is also called early liver cancer. But fatigue, boredom, dull complexion, abdominal distension and abnormal liver function are not the specific manifestations of liver cancer.

There are several reasons for the occurrence of liver cancer. Infected with viral hepatitis, of which hepatitis B and hepatitis C are the most likely to become cancerous. If patients are infected with both viruses at the same time, the canceration rate will double; 2. Liver cancer after cirrhosis, severe fatty liver, autoimmune liver and viral hepatitis may further develop into cirrhosis if alcoholic hepatitis is not controlled; 3. Liver cancer after alcoholic hepatitis is mostly induced by heavy drinking; 4. Liver cancer after Aspergillus flavus infection is mostly related to long-term consumption of moldy food; 5. Other factors. Among them, viral hepatitis combined with alcoholic hepatitis will greatly increase the incidence of liver cancer, so in daily life, we should try to avoid long-term heavy drinking. If you find viral hepatitis, you should treat it as soon as possible, avoid eating food infected by Aspergillus flavus, and at the same time pay attention to exercise and strengthen your physique.
