Knowing that, you would be forgiven for thinking the liver was indestructible. However, liver cancer is one of the few cancers that are on the rise,3 and hepatocellular carcinoma (HCC), the primary type of liver cancer, accounts for 90% of those cases.4
You’re probably aware of the link between alcohol and the liver, but have you thought about what else impacts your liver?
Worldwide, the most common risk factor for HCC is viral hepatitis6 – known to cause inflammation of the liver.4 Chronic hepatitis B accounts for approximately 50% of all cases of HCC, and the majority of cases of childhood HCC.7 Other risk factors include aflatoxin – a carcinogenic mould found in contaminated foods such as rice, in hot and humid climates.4
An increasingly important risk factor for the development of HCC is non-alcoholic fatty liver disease (NAFLD), linked with fatty foods and obesity.8 For example, in the US, the number of liver cancer cases have doubled since the mid-1980s, the fastest-growing rate of any cancer; this is thought to be driven in part by this risk factor, along with alcohol use.9 In recent years, NAFLD has spread to other regions, such as Asia.10
Viral hepatitis B has a particularly high prevalence in most countries in Asia,6,11 and this prevalence directly contributes to higher incidences of HCC in the region.6
In North America and Europe, hepatitis C (HCV) is the predominant cause of HCC12 – in the US, HCV is linked to 34% of cases of HCC.12
In the 1980s and 1990s, great strides were made in China and elsewhere in Asia to tackle hepatitis B, in an effort to reduce the number of HCC cases, through universal vaccination programmes.13,14
Thanks to these efforts, data show that the incidence of HCC is beginning to fall in some high-incidence areas in Asia7 – for example, Taiwan halved the incidence of childhood HCC within a decade.14
Similarly, if caught early enough and appropriate diet and exercise changes are made, some of the damage caused by liver disease, as a result of poor diet and lifestyle, can be reversed.15

Do you know what can cause hepatocellular carcinoma, the primary form of liver cancer?
Being faced with a cancer diagnosis can be devastating, but imagine if you had been living with HCC for a while without realising; by the time you were diagnosed, it’s likely your treatment options would be limited.4,16,17,18
Many cases of liver cancer are diagnosed at an advanced stage, usually once symptoms appear,4 where less than 50% of people with advanced HCC will survive more than a year after diagnosis.16 If diagnosed early, it may be possible to remove the cancer completely.4,18
There are limited treatments available for people across all stages of liver cancer, and even less if diagnosed at the advanced stage.
Current treatment options include:18
Embolisation, which involves blocking blood cells in the liver that supply the tumour
Destroying cancer cells with heat or cold (ablation procedures)
Chemotherapy or radiation directly to cancer cells
Radiation therapy using energy from X-rays or protons
Targeted drug therapies such as tyrosine kinase inhibitors
Immunotherapies, which enhance the body’s natural ability to recognize and destroy cancer cells
Recent developments in screening, vaccinations and new treatments are great advances, but with over 900,000 new cases of HCC diagnosed each year globally,4,5 further research and understanding of this complex disease is urgently needed.
Immune checkpoint inhibitors, some of which target the PD-L1 and PD-1 proteins, are being explored as a potential new treatment option for people with HCC.19
We believe people with HCC deserve more options, and our hope for the future is to be a helping hand for those who need it.
