Hepatitis B and Cancer Risk: What You Need to Know
"New research highlights a significant link between past Hepatitis B infections and an increased risk of certain blood cancers. Learn how to protect yourself."
Hepatitis B virus (HBV) is a widespread global infection, especially prevalent in Asia and Africa. While many know about its link to liver cancer (hepatocellular carcinoma or HCC), emerging research suggests a connection to other cancers as well. The good news is that there is a vaccine against HBV and it is recommended for all infants and children. Adults can also get vaccinated to prevent HBV.
Almost 10% of human cancers are triggered by oncovirus infections. While some viruses like human herpesvirus and Epstein-Barr virus are already linked to blood cancers, the role of HBV is still being explored. Because HBV can replicate in lymphoid cells, it might play a role in the development of hematological malignancies.
A recent large-scale study in China investigated the potential link between HBV infection and hematological malignancies. This retrospective cohort study looked at a large number of patients to evaluate the association between past HBV infection and the risk of developing blood cancers.
Unveiling the HBV-Blood Cancer Connection: What the Study Showed

The study, conducted at Shanghai Ruijin Hospital, analyzed data from 86,115 patients admitted between 2008 and 2015. The researchers compared two groups: those with prior HBV exposure (indicated by the presence of anti-HBc antibodies) and those without.
- Higher Prevalence of Past HBV Exposure: A significantly larger percentage of patients with hematological malignancies showed evidence of past HBV exposure compared to the control group (61.2% vs. 54.3%).
- Increased Risk of Specific Blood Cancers: The study revealed a higher risk of B-cell non-Hodgkin's lymphoma, acute lymphoblastic leukemia, and multiple myeloma in the HBV-infected group.
- No Association with HBsAg Positivity: Interestingly, current HBV infection (indicated by HBsAg positivity) was not associated with an increased risk of blood cancers in this study. This contrasts with some previous research and may be due to the study's inclusion of all types of hematological malignancies.
What This Means for You: Taking Control of Your Health
While this research highlights a potential risk, it's important to remember that having HBV exposure doesn't guarantee you'll develop a blood cancer. However, it does underscore the importance of awareness and proactive healthcare. Talk to your doctor about your HBV status, especially if you have a history of HBV infection or live in an area with high HBV prevalence. Regular check-ups and screenings can help detect any potential problems early, when they are most treatable.
