Liver Cancer (Hepatocellular Carcinoma) in Nigeria

Q: How common is liver cancer in Nigeria?

Nigeria has one of the highest liver cancer incidence rates in the world — over 40 new cases per 100,000 men per year in some regions. It is the most common fatal cancer in young Nigerian men in some series. The driver is the 11% chronic hepatitis B carrier rate.

Q: If I have hepatitis B, will I get liver cancer?

Not necessarily — but your lifetime risk is 15–40% without treatment, especially if acquired in childhood (as most Nigerian hepatitis B is transmitted at birth or in early childhood). Antiviral therapy with tenofovir dramatically reduces this risk. Regular surveillance catches cancer early when it is treatable.

Q: Is hepatitis B curable?

Not cured, but suppressed. Modern antiviral drugs (tenofovir, entecavir) suppress hepatitis B to undetectable levels in most patients, prevent cirrhosis, and reduce liver cancer risk by 70–80%. Treatment is lifelong for most people.

Q: What are aflatoxins and how do I avoid them?

Aflatoxins are toxins produced by the mould Aspergillus flavus, which grows on groundnuts, corn, and other grains stored in warm, humid conditions. They are a potent liver carcinogen. Avoid eating mouldy or discoloured groundnuts; store grains properly; buy from reputable suppliers where possible.

Q: What is the survival rate for liver cancer?

Without treatment: median survival is 3–6 months from diagnosis. With early detection and surgery or ablation: 5-year survival of 40–70%. With TACE: median survival of 20–30 months. Prevention and early detection are the key strategies that matter most in Nigeria's context.

Nigeria's most deadly cancer — and why prevention is everything

Hepatocellular carcinoma (HCC) — primary liver cancer — has one of the worst prognoses of any cancer in Nigeria. It kills quickly, often within months of diagnosis. Nigeria has some of the highest HCC rates in the world because of two underlying causes: chronic hepatitis B infection (affecting 11% of Nigerians) and aflatoxin exposure from mouldy groundnuts and grains. Both are preventable. HCC is a cancer where prevention and early detection truly save lives.

Signs and Symptoms

✓ Most early liver cancer has NO symptoms

✓ Abdominal pain or discomfort — especially in the right upper abdomen

✓ Unexplained weight loss and loss of appetite

✓ Nausea and vomiting

✓ General fatigue and weakness

✓ Abdominal swelling (ascites — fluid buildup in the belly)

✓ Jaundice — yellowing of skin and whites of eyes

✓ A hard, tender mass felt under the right rib cage

✓ Fever without obvious infection

Risk Factors

Chronic hepatitis B infection — the dominant cause of HCC in Nigeria
Chronic hepatitis C infection
Aflatoxin exposure — mouldy groundnuts, corn, cassava (a unique West African risk factor)
Liver cirrhosis from any cause
Heavy alcohol use
Non-alcoholic fatty liver disease (NAFLD) — increasingly common with obesity
Diabetes — independently increases liver cancer risk
Male sex — 3 times more common in men
Family history of liver cancer

When to Seek Help

Known chronic hepatitis B — surveillance every 6 monthsLiver ultrasound + AFP (alpha-fetoprotein) blood test every 6 months is the standard surveillance for all people with chronic hepatitis B — regardless of symptoms.

Jaundice + abdominal massUrgent assessment — may represent advanced liver cancer, biliary obstruction, or other serious liver disease.

Unexplained ascites (fluid in abdomen)New abdominal swelling in someone with liver disease or hepatitis B should be assessed urgently.

Rapid unexplained weight lossIn someone with hepatitis B or known liver disease, rapid weight loss warrants urgent imaging.

Tests & Diagnosis

🧪 Liver ultrasound

The first-line surveillance and diagnostic tool. Can detect HCC tumours from 1 cm. Done every 6 months in high-risk patients.

🧪 AFP (alpha-fetoprotein) blood test

A tumour marker — elevated in HCC (but not always; some HCCs have normal AFP). Used alongside ultrasound for surveillance.

🧪 Triple-phase CT or MRI of the liver

Definitive imaging for suspected HCC — the contrast enhancement pattern (arterial enhancement + washout) is diagnostic without biopsy in most cases.

🧪 Liver biopsy

Sometimes needed when imaging is inconclusive. Not always required if imaging is classic.

🧪 Hepatitis B and C serology

All patients with newly diagnosed liver cancer should be tested for hepatitis B and C.

🧪 Liver function tests + Child-Pugh score

Assesses underlying liver function — critical for determining which treatments are safe.

Treatment Options

Hepatitis B vaccination — prevention

The hepatitis B vaccine is 95% effective at preventing hepatitis B and thereby preventing most liver cancer in Nigeria. All unvaccinated Nigerians should be vaccinated. It is part of the routine childhood immunisation schedule; catch-up vaccination for adults is available.

Antiviral therapy for hepatitis B

Tenofovir or entecavir suppresses hepatitis B replication and dramatically reduces liver cancer risk in people with chronic infection. Free or subsidised through PEPFAR-supported programmes in Nigeria.

Avoid aflatoxin exposure

Do not eat mouldy groundnuts, corn, or grains. Store grains in cool, dry conditions. This is a modifiable risk factor unique to West Africa.

Surgical resection

Removal of the liver tumour — potentially curative for small, solitary tumours in patients with good liver function. Available at specialist hepatobiliary surgery centres.

Liver transplant

Curative for selected patients meeting Milan criteria (1 tumour <5 cm or up to 3 tumours <3 cm each, no vascular invasion). Not widely available in Nigeria.

Ablation (RFA/microwave)

Radiofrequency or microwave ablation destroys small tumours using heat delivered through a needle. Available at some Lagos private hospitals.

TACE (trans-arterial chemoembolisation)

Delivers chemotherapy directly into the tumour's blood supply while blocking it. Used for intermediate-stage HCC not amenable to surgery.

Sorafenib / Lenvatinib

Systemic targeted therapy for advanced HCC — prolongs survival in patients with preserved liver function. Available but expensive.
