AI Summary Metastatic liver cancer starts in another organ, such as the colon, lung, or breast, and spreads to the liver. It is more common in the United States than cancer that begins in the liver. Early on it may cause no symptoms; later signs include fatigue, weight loss, upper right abdominal pain, and jaundice. Doctors use blood tests, imaging, and sometimes a biopsy. Treatment depends on where the cancer began and how far it has spread.
Medically reviewed.
Metastatic liver cancer is cancer that started in another organ, such as the colon, lung, breast, or stomach, and has spread (metastasized) to the liver. It is named after the organ where it began — for example, cancer that spreads from the colon to the liver is still called metastatic colon cancer, even though tumors are now present in the liver.
Cancer that spreads to the liver is more common in the United States than cancer that starts in the liver itself, such as hepatocellular carcinoma. Treatment and outlook depend on where the cancer began, how much of the liver is involved, and whether it has spread beyond the liver.

About Metastatic Liver Cancer
Metastatic liver cancer, also called secondary liver cancer, is cancer that began in another organ and spread to the liver. Cancer is always named after where it started, so cancer that spreads from the colon to the liver is called metastatic colon cancer, not liver cancer, even though it is now growing in the liver.
This is different from primary liver cancer, such as hepatocellular carcinoma or cholangiocarcinoma, which starts in the liver's own cells or bile ducts. Cancer that spreads to the liver from elsewhere in the body is actually more common in the United States than cancer that begins in the liver itself.
The liver receives blood from the stomach, spleen, intestines, and pancreas through a large vessel called the portal vein, in addition to blood from the rest of the body through the hepatic artery. This rich, dual blood supply is one reason cancer cells from other organs, especially those in the digestive tract, often travel to and settle in the liver.
Cancers of the colon and rectum, lung, and breast are among the cancers that most often spread to the liver, and doctors sometimes use specialized tissue staining to help confirm where a liver tumor originated.
How doctors approach metastatic liver cancer depends heavily on how much of the liver is involved and whether the cancer has spread beyond the liver.
Symptoms
Metastatic liver cancer often causes no symptoms early on, especially when only a small part of the liver is affected. Symptoms tend to appear as more of the liver becomes involved.
Getting Checked
Metastatic liver cancer is usually found through a combination of physical examination, blood tests, and imaging, and confirmed with a biopsy when needed.
Doctors may perform a liver biopsy to confirm metastatic liver cancer and to run genetic testing on the tumor, which can help determine the most appropriate treatment.
Care & Treatment
Treatment for metastatic liver cancer depends on where the cancer started, how many tumors are in the liver, whether the rest of the liver is healthy, and whether the cancer has spread beyond the liver. Your care team, often including a medical oncologist, hepatologist, and interventional radiologist, will tailor a plan to your situation.
If the cancer has not spread beyond the liver and the rest of the liver is healthy, options may include partial hepatectomy (surgical removal of the affected part of the liver) or radiofrequency ablation, which uses a heated probe to destroy tumor cells.
When tumors are more widespread in the liver or do not respond to surgery or ablation, doctors may use procedures that block the tumor's blood supply, such as bland embolization, chemoembolization, or radioembolization, or radiation therapy aimed at the liver.
If the cancer has spread outside the liver, or has not responded to liver-directed treatments, doctors may recommend oral anti-cancer medications, immunotherapy, or clinical trials, often used in combination. Because metastatic liver cancer is named for its organ of origin, systemic treatment usually follows the guidelines for that original cancer type (for example, colon or breast cancer treatment protocols) while also accounting for how the liver is affected.
There is no single treatment for metastatic liver cancer. The right approach depends on the original cancer type, how much of the liver is involved, and whether the disease has spread further.
How Metastatic Liver Cancer Develops
Metastatic liver cancer happens when cancer cells from another organ travel through the bloodstream and settle in the liver. Certain cancers spread to the liver more often than others, largely because of how blood flows from the digestive organs through the liver.
Cancers of the colon and rectum, lung, and breast are among the most common sources of metastatic liver cancer, and cancer that spreads to the liver from these organs is more common in the United States than cancer that starts in the liver itself.
When to Get Checked
If you have already been diagnosed with cancer elsewhere in the body, your care team will typically monitor your liver as part of routine follow-up. Talk with your doctor promptly if you notice new or worsening symptoms.
Contact your healthcare provider if you have a history of cancer and develop new fatigue, unexplained weight loss, loss of appetite, right upper abdominal discomfort, yellowing of the skin or eyes, or abdominal swelling. These can be signs that cancer has spread to the liver and should be evaluated promptly.
Metastatic liver cancer can develop with few early symptoms. If you have a history of cancer, ask your care team how they monitor for signs that cancer has spread to the liver as part of your follow-up care. Catching liver involvement early opens the door to more treatment options.
Care for metastatic liver cancer works best as a team effort. Depending on your situation, your care team may include your original oncologist along with a hepatologist, interventional radiologist, and surgeon, who together tailor a plan to your specific cancer type and how it affects your liver.

Eating & liver health
Diet cannot treat metastatic liver cancer on its own. Good nutrition supports your liver and your strength during treatment. Cancer treatments such as chemotherapy can affect appetite and how your body handles food.
A liver-friendly eating pattern emphasizes vegetables, fruits, lean proteins, and whole grains. It limits added sugar, salt, and trans and saturated fats. If you have advanced liver disease, your care team may ask you to cut back on salt further. Drinking enough water throughout the day also helps your body work properly.
If your appetite is poor, eating small, frequent meals may help. Nutrition needs can change quickly during cancer treatment and vary with how much of the liver is involved. Work with your oncology or hepatology care team, or a registered dietitian, to build an eating plan before you make major changes.

Metastatic liver cancer starts in another organ, such as the colon, lung, or breast, and spreads to the liver. Primary liver cancer, such as hepatocellular carcinoma, begins in the liver's own cells or bile ducts. Cancer is named for where it began, so colon cancer that spreads to the liver is still called metastatic colon cancer. This matters because the original cancer type usually guides treatment.
Yes. In the United States, cancer that spreads to the liver from another organ is more common than cancer that begins in the liver. The liver filters blood from the whole body, so cancer cells traveling in the bloodstream can settle there.
Cancers of the colon and rectum, lung, and breast are among the cancers that most often spread to the liver. Digestive-tract cancers have a direct route. Blood from the stomach, spleen, intestines, and pancreas drains through the portal vein straight into the liver. How advanced the original cancer is and how well it responds to treatment also play a role.
Metastatic liver cancer often causes no symptoms early on. When symptoms appear, they can include fatigue, loss of appetite, unexplained weight loss, nausea, fever, and pressure or pain in the upper right abdomen. In more advanced cases, people may have jaundice (yellowing of the skin or eyes), abdominal swelling from fluid, or easy bruising. If you have a history of cancer, tell your care team promptly about any new symptoms.
Doctors use a combination of a physical exam, blood tests, and imaging. Liver function tests show how well the liver is working. Ultrasound, CT, or MRI can find tumors and show how many there are and how large. Sometimes a liver biopsy removes a small piece of tissue to confirm the diagnosis. Doctors may also run genetic testing on the tumor to help choose the best treatment.
Treatment depends on where the cancer started, how many tumors are in the liver, whether the rest of the liver is healthy, and whether the cancer has spread beyond the liver. If the disease is limited to the liver, options may include partial removal of the liver or radiofrequency ablation. If tumors are more widespread in the liver, doctors may block the tumor's blood supply or use radiation. If the cancer has spread beyond the liver, oral anti-cancer medications, immunotherapy, or clinical trials may be used, often together. Your care team will tailor the plan to you.
