Secondary liver cancer
Secondary cancer in the liver is cancer that started in another part of the body, but has now spread (metastasised) to the liver. This means it is advanced cancer. Secondary cancer in the liver is much more common than primary liver cancer in Australia.

What is secondary liver cancer?
Many cancers can spread to the liver. The most common cancer that spreads to the liver is bowel cancer. This is because the blood supply from the bowel is connected to the liver through the portal vein. Melanoma and cancer in the breast, oesophagus, stomach, pancreas, ovary, kidney or lung can also spread to the liver.
Secondary cancer in the liver may be diagnosed:
- at the same time as the original cancer (the primary cancer)
- soon after the primary cancer is found
- months or years after the primary cancer has been treated
- before the primary cancer is found
- when tests can’t find where the cancer started – this is known as cancer of unknown primary (CUP).
If you have secondary cancer in the liver, you may find it useful to read about the primary cancer type or CUP.
The liver
The liver is the largest organ inside the body. It is found above the stomach on the right side of the abdomen (belly) under the ribs. The gall bladder sits under the liver, and the pancreas sits under the stomach. These organs are all part of the digestive system. They work together to help the body break down food and turn it into energy.
The digestive system


How the liver works
The liver has two main sections: the right and left lobes. Blood flows into the liver from the hepatic artery and the portal vein. Blood in the hepatic artery comes from the heart and carries oxygen. Blood in the portal vein comes from the digestive organs and carries nutrients and substances such as medicines to the liver.
The liver does many important jobs. These include:
- breaking down drugs and alcohol, and getting rid of toxins
- producing bile to help dissolve fat so it can be easily digested
- storing and releasing sugars (glucose) as needed
- storing nutrients
- making proteins to help blood clot and to balance fluid in the body.
Unlike other internal organs, a healthy liver may be able to repair itself if it is injured. It can continue to function when only a small part is working and may grow back to its normal size in 6–8 weeks, even after a part is removed during surgery.
A substance called bile is made in the liver and stored in the gall bladder. Bile is carried between the liver and gall bladder by a series of tubes called bile ducts. The common bile duct carries bile from the liver and gall bladder to the bowel, where it helps to break down fats from food.
