Primary liver cancer is a rare but serious type of cancer that begins in the liver. It mostly affects older people.
Symptoms are often vague and don't appear until the cancer is at an advanced stage. They include:
- unexplained weight loss
- nausea (feeling sick)
- jaundice – yellowing of the skin and the whites of the eyes

The liver is one of the most complex organs in the human body. It performs more than 500 functions. Some of the liver’s most important functions include:
- digesting proteins and fats
- removing toxins (poisons) from the body
- helping to control blood clotting (thickening)
- releasing bile, a liquid that breaks down fats and aids digestion
Liver cancer is a serious condition because it can disrupt these functions or cause them to fail completely.
Why does liver cancer happen?
Although the exact cause of liver cancer is unknown, it is thought to be related to damage to the liver, such as cirrhosis.
Cirrhosis can be caused by:
It is also believed that obesity may increase the risk of liver cancer due to its links with non-alcoholic fatty liver disease.

How common is liver cancer?
Liver cancer is rare in England, but much more common in other parts of the world.
In the UK, almost 4000 new cases of liver cancer are diagnosed each year. Around 60% of cases affect men and 40% affect women. The number of people affected by liver cancer rises sharply with age, about 70% of cases involve people 65 years of age or older.
Over the past few decades, rates of liver cancer in the UK have risen sharply as a result of increased levels of alcohol misuse and obesity.
Diagnosis and screening
Liver cancer is usually diagnosed after a consultation with a GP and a referral to a hospital specialist for further tests.
However, regular check-ups for liver cancer (known as ‘surveillance’) are recommended for people known to have a high risk of developing the condition, such as those with a confirmed hepatitis C infection or those who have had cirrhosis.
If you are in a high-risk group for developing liver cancer, having regular check-ups will help ensure the condition is diagnosed early. The earlier liver cancer is diagnosed, the more effective treatment is likely to be.

How is liver cancer treated?
Treatment for liver cancer depends on the stage the condition is at. If diagnosed early, it may be possible to treat.
Treatment options include:
- surgical resection – surgery is used to remove a section of liver
- liver transplant – the liver is replaced with a donor liver
- radiofrequency ablation – a small electrical current is used to destroy the cancerous cells
If liver cancer is only discovered at an advanced stage, treatment is only used to relieve pain and discomfort.
Currently, only 1 in 10 people is diagnosed for liver cancer at an early stage. In most people who are diagnosed with liver cancer, the cancer has advanced too far to be cured. As a result, only 1 in 5 people live for at least a year after being diagnosed with liver cancer. Just 1 in 20 people live for at least five years.

Preventing liver cancer
Many cases of liver cancer are preventable. Most steps to reduce the chances of liver cancer involve having a healthy lifestyle.
The risk of liver cancer can be reduced by:
- avoiding alcohol or excessive drinking
- eating healthily and keeping fit to avoid obesity
- reducing the chances of being infected by hepatitis B or hepatitis C
