Can Hepatitis B Surface Antigen Carriers Develop Into Liver Cancer?

Hepatitis B surface antigen carriers may have the potential to develop into liver cancer, but not all cases progress to this stage. In China, approximately 90% of liver cancer patients have a history of hepatitis B infection. The typical progression starts with chronic hepatitis B, followed by cirrhosis, and eventually leads to liver cancer. This pathway is the most common disease mechanism associated with hepatitis B.

The term "hepatitis B surface antigen carrier" refers to specific results in a hepatitis B antigen-antibody test, where the hepatitis B surface antigen, hepatitis B e antibody, and hepatitis B core antibody are all positive. However, this single indicator alone cannot determine the severity of the infection. Further tests, including liver function analysis, liver ultrasound, and hepatitis B virus DNA load testing, are essential for a comprehensive evaluation.

Many individuals with hepatitis B surface antigen show no clinical symptoms or signs of liver disease. Their serum liver function tests are generally normal, and imaging or histological studies of the liver reveal no significant abnormalities. This condition is known as being an asymptomatic hepatitis B virus carrier, which indicates the body is in an immune-tolerant phase. In this state, the virus does not cause significant damage to the liver tissue. This condition may persist throughout life or may evolve into chronic hepatitis B under certain triggering factors. Therefore, regular monitoring and follow-up are crucial for early detection of any changes.

In contrast, some individuals with hepatitis B surface antigen may experience clear clinical symptoms and abnormal liver function tests. In such cases, the person is classified as having chronic hepatitis B. When the condition meets the criteria for treatment, antiviral therapy should be initiated under medical supervision to manage the disease and prevent further progression.

In conclusion, while hepatitis B surface antigen carriers have a risk of developing liver cancer, early diagnosis, regular monitoring, and timely treatment can significantly reduce the likelihood of severe outcomes. Maintaining a healthy lifestyle, avoiding alcohol and liver-damaging substances, and following medical advice are key steps in managing hepatitis B effectively.
