Hepatitis B and liver cancer remain serious public health concerns in Singapore. Despite medical advancements, the country continues to face one of the highest rates of liver cancer in the developed world. Hepatitis B infection, in particular, plays a significant role in liver cancer development—often without early symptoms. This makes regular screening not only important but potentially lifesaving.
In this article, we will take you through how Hepatitis B increases your risk of liver cancer, the importance of early detection, and why regular screening is critical for those living in Singapore.

Understanding the Link Between Hepatitis B and Liver Cancer
Hepatitis B is a viral infection that primarily targets the liver. It is spread through blood, unprotected sex, or from mother to child during birth. In some individuals, the virus becomes chronic and remains in the body for years. Over time, this can lead to liver inflammation, scarring (cirrhosis), and eventually liver cancer—also known as hepatocellular carcinoma.
In Singapore, chronic Hepatitis B is one of the leading causes of liver cancer. Many individuals carry the virus without knowing it, particularly if they were born before the introduction of universal vaccination programmes. Without symptoms, the infection can silently damage the liver over decades.
Why Liver Cancer Is So Dangerous
Liver cancer is often called a “silent killer” because it rarely causes noticeable symptoms in its early stages. By the time liver cancer symptoms such as abdominal pain, unexplained weight loss, or jaundice appear, the disease is usually already advanced. At this stage, treatment becomes more difficult and survival rates decrease significantly.
This is why early detection of liver cancer is so important. For individuals living with Hepatitis B, regular liver cancer screening helps doctors identify signs of liver damage or tumors early, when treatment options are more effective and the chances of recovery are much higher.

The Ministry of Health in Singapore recommends that individuals at high risk, especially those with chronic Hepatitis B, undergo regular liver cancer screening. This typically involves blood tests to monitor liver function and imaging tests like ultrasound or CT scans to detect tumours early.
Screening is especially important if you:
- Were born in Singapore before 1987 (before the national Hepatitis B vaccination was introduced)
- Have a family history of liver cancer
- Are male and over 40, or female and over 50 with Hepatitis B
- Have liver cirrhosis or elevated liver enzymes
Singapore’s healthcare system offers access to affordable screening options. Early detection not only saves lives but also reduces the cost of treatment in the long term.
Can Liver Cancer Be Prevented?
Yes, to some extent. Vaccination against Hepatitis B is the first line of defence and is already included in the national childhood immunisation schedule. However, for those who already have the virus, prevention focuses on monitoring and managing the infection to reduce liver inflammation and avoid cirrhosis.
Doctors may prescribe antiviral medications to control the virus and reduce the chance of developing liver cancer. In addition, patients are advised to avoid alcohol, eat a liver-friendly diet, and maintain regular follow-ups.
