Liver Cancer in Vietnam?
I'm Shiloh, an 8th grader who's doing a research project about a country from Southeast Asia, and I chose Vietnam. We needed to study a public health issue there, and mine is liver cancer. I made questions to ask for people related in this field and has seen the impact in Vietnam or globally. To anyone is interested in answering, I would be glad!
- What should the government and society improve in order to prevent liver cancer before the disease develops?
- Where are the areas in Vietnam with the highest rate of liver cancer?
- Which groups of people are most vulnerable to developing liver cancer?
- When did liver cancer start becoming a major public health issue in Vietnam?
- What factors contribute to the high prevalence of liver cancer in these areas and among these populations?
- How is the Vietnamese government preparing to address and prevent this issue in the future?
- Why do hepatitis B and C remain major risk factors for liver cancer in Vietnam, even though hepatitis B can be prevented through vaccination?
- To what extent do social and environmental conditions affect people's risk of developing liver cancer?

Hi Shiloh! That's a really solid topic for your project. Liver cancer is a huge deal in Vietnam, and from what the research shows, it mostly comes down to how common chronic hepatitis B and C infections are there.
To answer your questions:
What needs to change?
The government and society really need to lean into hepatitis B vaccines (especially for newborns), get more screening programs out there, and make treatment easier to access. Basically, catching it early is the only way to stop the cancer before it even starts. Also, just general public awareness about liver health would go a long way.
Who's most at risk?
Definitely people already living with hep B or C. It's especially tough for people who caught it at birth or when they were little—they can carry the virus for years without knowing it, which eventually leads to cancer later on.
When did this become a big deal?
Vietnam has been struggling with hepatitis for decades. By 2012, the WHO actually flagged them as one of the countries with the highest death rates from liver cancer.
What's causing the problem?
Hep B and C are the main culprits, but other things play a role too—like drinking alcohol, metabolic issues, or even "aflatoxins" (which are toxins found in moldy food). Plus, in some areas, people just don't have easy access to a doctor for an early diagnosis.
What is Vietnam doing about it?
They've actually rolled out nationwide hep B vaccines and a national strategy to get rid of hepatitis entirely. They're also trying to make screening and treatment more available across the country.
If there's a vaccine, why is Hep B/C still such a problem?
A lot of adults were born before the vaccines were common. Also, the tricky thing about hepatitis is that you can have it for years without feeling a single symptom, so people don't realize they're sick until the damage is already done.
How do social/environmental things play in?
It really comes down to where you live and what you have access to. Things like clean food storage (to avoid those mold toxins) and having a clinic nearby for a quick check-up make a massive difference in whether someone develops cancer or not.
One cool takeaway for your project: a huge amount of these liver cancer cases in Vietnam are actually preventable if people can just get vaccinated, screened early, and treated.

Hi Shiloh! It is fantastic that you are exploring public health and tackling such an important global health topic for your 8th-grade research project.
Liver cancer—predominantly Hepatocellular Carcinoma (HCC)—is currently the leading cause of cancer deaths in Vietnam, accounting for tens of thousands of new cases each year according to the World Health Organization (WHO / GLOBOCAN data).
Here are detailed, structured answers to each of your research questions:
1. What should the government and society improve to prevent liver cancer before it develops?
Universal Birth-Dose Hepatitis B Vaccination: Ensuring that 100% of newborns receive the Hepatitis B vaccine within 24 hours of birth (the "birth dose"), especially in remote and rural areas.
Routine Screening & Early Detection: Providing affordable screening (ultrasounds and blood tests like AFP) for high-risk individuals (such as those living with chronic Hepatitis B or C) so pre-cancerous liver damage (cirrhosis) or small tumors are caught early.
Access to Antiviral Medications: Expanding public insurance coverage for direct-acting antivirals (DAAs), which can cure Hepatitis C in 8–12 weeks, and long-term antiviral suppressants for Hepatitis B.
Alcohol Regulation & Education: Introducing stricter policies, taxes, and public health campaigns to reduce high per-capita alcohol consumption, especially binge drinking among adult men.
Food Safety and Storage Standards: Preventing contamination of crops (corn, peanuts, rice) with Aflatoxin—a toxic fungus that grows in humid climates and directly damages liver DNA.
2. Where are the areas in Vietnam with the highest rates of liver cancer?
Rural and River Delta Regions: High rates are concentrated in the Red River Delta (North) and the Mekong River Delta (South).
Remote Mountainous Provinces: Northern highland and central mountainous areas often face higher mortality rates due to limited access to healthcare clinics, screening facilities, and specialized cancer treatment centers.
Urban vs. Rural Disparity: While urban hubs like Hanoi and Ho Chi Minh City report high absolute numbers because patients travel there for treatment, rural populations face disproportionate risk due to lower historic vaccination rates, water/crop sanitation challenges, and later diagnosis.
3. Which groups of people are most vulnerable to developing liver cancer?
Adult Men: Men in Vietnam are roughly 3 to 4 times more likely to develop liver cancer than women, largely due to higher rates of heavy alcohol use combined with viral hepatitis.
Older Adults (Ages 40–65+): Generations born before universal hepatitis vaccination was introduced in the 2000s are living with undetected chronic viral hepatitis.
Individuals with Chronic Hepatitis B (HBV) or Hepatitis C (HCV): These individuals make up roughly 70–80% of all liver cancer cases in Vietnam.
Low-Income and Rural Communities: Those with less access to regular medical checkups, clean water, and healthy food storage.
4. When did liver cancer start becoming a major public health issue in Vietnam?
Historical Baseline: Chronic hepatitis infections were widespread for decades, but liver cancer emerged as a recognized public health crisis in the 1990s and 2000s as life expectancy increased and epidemiological tracking improved.
Leading Cancer Cause: By the 2010s and 2020s, liver cancer overtook lung cancer and stomach cancer to become the number one cause of cancer incidence and cancer-related deaths in Vietnam according to WHO GLOBOCAN reports.
5. What factors contribute to the high prevalence in these areas and populations?
The "Synergistic" Multiplier Effect: The combination of chronic viral hepatitis (HBV/HCV) plus heavy alcohol consumption multiplies the risk exponentially compared to either factor alone.
Late-Stage Diagnosis: The liver has no pain receptors, so early-stage liver damage is "silent." Without routine screening, most patients only visit the doctor when symptoms (jaundice, abdominal swelling, severe pain) appear, at which point the cancer is advanced.
Environmental Toxins (Aflatoxin): Vietnam’s tropical, humid climate promotes mold growth (Aspergillus flavus) on poorly stored grains and legumes.
6. How is the Vietnamese government preparing to address and prevent this issue in the future?
National Action Plan for Viral Hepatitis: Setting targets to eliminate viral hepatitis as a public health threat in alignment with WHO guidelines.
Expanded National Expanded Program on Immunization (EPI): Strengthening delivery systems to reach rural newborns with the Hep B birth dose.
Decentralizing Care: Training commune and district health centers to run basic blood tests and ultrasound screenings rather than requiring all patients to travel to major tertiary hospitals.
Alcohol Harm Prevention Law: Implementing laws to regulate alcohol advertising, restrict sales to minors, and enforce strict penalties for drunk driving.
7. Why do Hepatitis B and C remain major risk factors despite the Hep B vaccine?
The "Generational Gap": The Hepatitis B vaccine was only integrated into Vietnam's Expanded Program on Immunization in 1997 and scaled nationally in the 2000s. Millions of adults born before the late 1990s never received the vaccine as infants.
Birth-Dose Timing Challenges: In remote mountainous areas where home births occur, administering the vaccine within the critical first 24 hours of life can be logistically difficult.
Hepatitis C Has No Vaccine: While Hep C can be cured with medicine, there is no preventative vaccine, and transmission through unsterilized medical/dental equipment or needle sharing in past decades created a pool of chronic carriers.
Lack of Symptoms: Many people carry Hep B or C for 20 to 30 years without knowing it, until it has already progressed to liver cirrhosis or cancer.
8. To what extent do social and environmental conditions affect risk?
Social and Cultural Factors: Social gatherings frequently center around heavy alcohol consumption (especially home-brewed rice wine or beer).
Economic Inequality & Healthcare Access: Lower-income families may avoid preventive checkups due to out-of-pocket costs or travel distance to regional hospitals.
Climate & Storage Environment: High humidity and seasonal monsoons accelerate mold growth on staple crops, leading to dietary aflatoxin exposure.
Historical Medical Practices: Past use of non-disposable syringes or unsterilized equipment before modern blood-screening protocols were established contributed to transmission in earlier generations.
Suggested Key Takeaway for Your Project:
Liver cancer in Vietnam is a multi-factor disease where biology (viral hepatitis), environment (humid climate / aflatoxin), and culture (alcohol consumption) intersect. The most effective path forward is a combination of universal infant vaccination, expanding affordable viral screening, and encouraging early routine checkups.
Good luck with your 8th-grade research presentation!

Hi Shiloh! You chose an important topic. Liver cancer is a major public-health challenge in Vietnam, and many cases are connected to infections that can potentially be prevented, detected, or treated earlier. I looked at current information from the World Health Organization (WHO) and the International Agency for Research on Cancer (IARC) to help answer your questions.
1. What should the government and society improve to prevent liver cancer before it develops?
One of the biggest opportunities is preventing and treating hepatitis B and hepatitis C. WHO reports that hepatitis B and C are responsible for about 90% of liver cancer cases in Vietnam. More than 7 million people in the country are estimated to be living with one of these infections.
Vietnam can continue to strengthen hepatitis B vaccination, especially making sure newborns receive the first dose within 24 hours of birth. It can also expand hepatitis B and C testing, make treatment more affordable and accessible, screen pregnant women for hepatitis B, educate people about hepatitis, and encourage earlier medical care. Reducing harmful alcohol use and other cancer risks is also important.
2. Where are the areas in Vietnam with the highest rates of liver cancer?
This question is harder to answer accurately because the strongest current international cancer databases provide national estimates, rather than a reliable ranking of every Vietnamese province.
What we can say confidently is that Vietnam as a whole has a very high burden. IARC’s GLOBOCAN 2022 data ranked liver cancer as the second most common cancer overall in Vietnam and the most common cancer among Vietnamese men.
For your project, I would be careful about naming a particular province as having the “highest rate” unless you find a Vietnamese cancer-registry study that specifically compares provinces.
3. Which groups are most vulnerable?
People with chronic hepatitis B or C infections are especially vulnerable. WHO also reports that hepatitis B and C infection in Vietnam is more common among adults over age 25. Men carry a particularly large burden from liver cancer; WHO’s 2021 estimates show liver cancer among the leading causes of death for Vietnamese men.
Other factors can increase risk as well, including cirrhosis, heavy alcohol consumption and other conditions that damage the liver.
4. When did liver cancer become a major public-health issue in Vietnam?
There isn’t one specific year when liver cancer suddenly became a major problem. Instead, Vietnam has experienced a long-standing burden of chronic hepatitis B and C, infections that can remain unnoticed for years or even decades before causing cirrhosis or liver cancer.
For example, WHO was already reporting in 2019 that millions of Vietnamese people were living with hepatitis B or C and that testing and treatment coverage remained low.
So I would describe liver cancer as a long-term public-health problem rather than an outbreak that began at a particular moment.
5. What factors contribute to the high prevalence?
The biggest factor is chronic viral hepatitis. Hepatitis B and C can cause long-term inflammation and damage to the liver, eventually leading to cirrhosis and cancer.
There are additional risks. Alcohol consumption can contribute to liver disease and cancer, while hepatitis C can spread through infected blood, including unsafe injections, sharing needles or syringes, and unsafe medical procedures.
An important thing to understand is that these risks can overlap. Someone who already has chronic hepatitis and also experiences additional liver damage can face greater health problems over time.
6. How is the Vietnamese government preparing to address this issue?
Vietnam is working with WHO to expand prevention, diagnosis and treatment of hepatitis B and C. Current efforts include hepatitis B screening during pregnancy, vaccination of newborns, harm-reduction programs, increased testing and treatment, and efforts to make treatment more affordable through health-insurance coverage.
This is important because preventing and treating hepatitis doesn’t just fight an infectious disease. It can also prevent cancer many years later.
7. Why are hepatitis B and C still major risk factors if hepatitis B can be prevented with a vaccine?
This is a great question.
The hepatitis B vaccine prevents new infections, but it does not eliminate infections that people already have. Millions of Vietnamese adults were infected previously, and chronic hepatitis B can remain in someone’s body for decades.
There are also challenges in making sure every newborn receives the vaccine quickly enough. WHO emphasizes that the first hepatitis B vaccine dose should be given within 24 hours of birth, followed by the remaining recommended doses.
And there is another important difference: there is currently no vaccine for hepatitis C. The good news is that modern antiviral medications can cure more than 95% of hepatitis C infections.
8. How much do social and environmental conditions affect liver-cancer risk?
They can matter a great deal, especially because social conditions affect whether people can access vaccination, testing, diagnosis and treatment.
Imagine two people who both have hepatitis B. One knows they have it, receives regular medical care and treatment, and is monitored for liver disease. The other doesn’t know they are infected and doesn’t have easy access to healthcare. Their chances of detecting and preventing serious complications can be very different.
WHO has specifically identified barriers involving diagnosis, treatment access and the cost of hepatitis C treatment in Vietnam.
The big idea I would take away for your project, Shiloh, is this: Vietnam’s liver-cancer problem isn’t only about treating cancer after someone becomes sick. A major part of the solution is stopping the chain much earlier:
Vaccination → hepatitis prevention → testing → early diagnosis → treatment → fewer cases of liver disease and liver cancer.
That makes liver cancer in Vietnam a really interesting example of how infectious disease, cancer, healthcare access, education and social conditions are all connected.
