A silent gap in modern healthcare is costing lives, and doctors now warn it is not because treatments are failing but because the disease is being caught too late. A new clinical update from the American Gastroenterological Association (AGA), published in Gastroenterology, has flagged a stark reality: nearly 70% of liver cancer cases are diagnosed at a stage when cure is no longer possible, even though early-stage disease can often be treated successfully.

Liver cancer, specifically hepatocellular carcinoma (HCC), is already the third leading cause of cancer-related deaths worldwide. What makes the situation more troubling is that only 3 to 4 out of every 10 patients are diagnosed early. In simple terms, this means that for every three people with liver cancer, two are finding out too late.

“We are not missing the cure; we are missing the moment,” said a senior liver specialist involved in the update, underlining that timing—not technology—is now the biggest barrier to survival.

At the heart of the problem are what doctors describe as "hidden scars." Known medically as cirrhosis, this permanent scarring of the liver often develops quietly over years. It acts as a magnet for cancer, elevating the risk without manifesting obvious symptoms in the initial stages. Many patients feel fine until the disease has already advanced.

The AGA’s guidance offers a surprisingly simple solution: a “double-test” every six months. This includes an ultrasound scan, which works like a security check inside the body, and a blood test called alpha-fetoprotein (AFP), which can act as an early warning signal. Together, they form a basic but powerful screening tool.

The expert emphasised that a six-month delay can significantly impact the outcome, highlighting the need for this routine check to reach more individuals in real-world settings.

The urgency has grown as the face of liver cancer begins to change. For decades, viral infections like hepatitis B and C were the main culprits. Today, lifestyle is emerging as a stronger driver. Conditions such as metabolic dysfunction–associated steatotic liver disease (MASLD)—commonly linked to fatty diets and diabetes—and alcohol-related liver disease (ALD) are now the fastest-growing causes.

This shift means the risk is no longer limited to a smaller, infected population. It is expanding into everyday life, tied to what people eat and drink and how they live.

The AGA update outlines practical steps to address these issues. Prevention remains the first line of defence—vaccination against hepatitis B, timely treatment of hepatitis C, reducing alcohol intake, and managing weight and blood sugar levels. But for those already living with liver damage, regular surveillance is critical.

Despite clear evidence that routine screening improves survival, its uptake remains surprisingly low. Doctors point to gaps in awareness, access, and consistent follow-up as key barriers to routine screening for liver damage, which ultimately affects patient outcomes and survival rates.

Meanwhile, science is pushing forward. In research labs, teams are studying new blood markers and imaging tools that could detect cancer even earlier. Trials like TRACER and PREMIUM are investigating the potential of these newer methods in conjunction with existing tests. At the same time, advanced prediction models like the PAGED-B score, which is a specific scoring system for assessing cancer risk, and machine learning systems such as SMART-HCC, which uses algorithms to analyse healthcare data, are being developed to identify high-risk patients more precisely.

After months of analysing patient data and blood samples, researchers are beginning to see patterns—tiny biological signals that may one day help doctors predict cancer before it even forms. But for now, these tools are still under validation and not widely available.

The message from experts remains clear and urgent. Liver cancer does not have to lead to death. The tools to detect it early already exist, but they are being underused.

For millions living with liver scarring—whether from an old infection or modern lifestyle habits—the solution may be as simple as showing up for a check-up twice a year. Missing that window, doctors warn, could mean missing the only chance to cure the disease.
