Can hepatitis b infection cause liver cancer?

Many people with hepatitis B do not develop liver cancer. Individual risk depends on the activity of the infection, the condition of the liver and other health factors, which is why personalised follow-up matters.

Hepatitis B infects liver cells. When infection becomes chronic, repeated injury and repair can lead to scarring called fibrosis; advanced scarring is called cirrhosis. This damaged environment can allow abnormal liver cells to grow into cancer.

Liver cancer can also arise in some people with chronic hepatitis B who do not have cirrhosis. Normal day-to-day wellbeing does not show whether the virus is active or whether silent liver damage is present, so blood tests and imaging are more informative than symptoms alone.

Attend the monitoring arranged by your liver specialist. This may include tests of liver function and viral activity, as well as liver imaging at intervals chosen for your circumstances. Antiviral medicine can suppress hepatitis B and reduce ongoing liver damage, but it should be taken exactly as prescribed and not stopped without specialist advice.

Tell every clinician treating you that you have hepatitis B, particularly before chemotherapy, immune-suppressing treatment or steroid therapy, because the virus can reactivate. Avoid sharing razors or toothbrushes, cover open wounds and discuss testing and vaccination for household or sexual contacts with a healthcare professional.

Contact your clinician soon if you develop persistent discomfort in the upper right abdomen, unexplained weight loss, reduced appetite, increasing tiredness, abdominal swelling, yellowing of the skin or eyes, dark urine or pale stools. These symptoms do not establish cancer, but they need assessment for liver disease and other causes.

Get urgent medical help for vomiting blood, black tar-like stools, severe confusion, marked drowsiness, fainting, rapidly increasing abdominal swelling or severe abdominal pain. These may be signs of bleeding or serious loss of liver function.

Ask whether your infection is chronic, whether there is evidence of fibrosis or cirrhosis, and whether antiviral treatment is indicated. Clarify which blood tests and scans you need, how often they should occur, what changes should prompt an earlier visit, and which medicines or supplements could affect your liver.
