Is liver cancer really contagious? Within the high incidence area of liver cancer, there are many liver cancer patients who have a family history of liver cancer in their families, and there are also several cases of liver cancer patients occurring in one family. Why is this phenomenon? Could it be that liver cancer is hereditary? Epidemiological investigations have revealed that there is also an aggregation of viral hepatitis infection in these families. For example, 70-90% of newborns born to parents with hepatitis, especially those with HbeAG (hepatitis B virus e antigen) positive, become asymptomatic hepatitis B carriers, or family members of hepatitis patients are in close contact, so if one of them is infected with hepatitis B virus, it is easy to unknowingly spread to others. Another point worth noting is that the dietary habits and lifestyles of family members are basically the same, so the chances of exposure to cancer-causing factors are also basically equal. According to a study, 80% of cancer patients are related to their living habits. Thus, liver cancer itself is not contagious. The family aggregation of liver cancer patients is caused by the mutual transmission of living habits plus diseases. Early stage liver cancer may have no symptoms and signs, and once typical clinical manifestations appear, it already belongs to middle and late stage liver cancer. Common symptoms of liver cancer include pain in liver area, poor appetite, emaciation, weakness, unexplained fever, abdominal distension, diarrhea, jaundice, etc. Many complications often occur in the late stage of liver cancer, such as upper gastrointestinal bleeding, hepatic encephalopathy, liver and kidney failure, rupture and bleeding of huge cancer tumor and cancerous chest and ascites, which are often life-threatening.
