The time for hepatitis B to develop into liver cancer is not fixed and not all patients with hepatitis B will develop liver cancer. The time for hepatitis B to develop into liver cancer is related to the severity of the disease and whether it is treated in time and actively. A small number of patients with hepatitis B who are not actively treated and whose condition gradually worsens may develop liver cancer in about 10 to 15 years. The transformation of hepatitis B into liver cancer generally goes through three stages: hepatitis – cirrhosis – liver cancer. If the patient actively undergoes antiviral treatment after hepatitis B is detected, the replication of hepatitis B virus in the body is not active, the damage to the liver is small, and the liver does not show serious changes such as liver fibrosis and cirrhosis, the patient will not progress to liver cancer. Depending on the type of hepatitis, the cause of the disease, the patient’s physical condition, and the immune status of the body, there are big differences, and it can develop into liver cancer in about 10 to 15 years. Therefore, it is recommended that patients seek early medical treatment and pay attention to their daily dietary habits and routine, which can reduce the probability of developing liver cancer.
