Metastatic Liver Disease
What is Metastatic Liver Disease?
Metastatic liver disease happens when cancer from another part of your body spreads to your liver. The liver is one of the most common sites for cancer to spread because of how blood flows through your body. Your liver filters large amounts of blood every day, which makes it vulnerable to circulating cancer cells.
This condition is different from primary liver cancer, which starts in the liver itself. Most often, metastatic liver disease comes from colorectal cancer, but it can also spread from breast, lung, pancreatic, and stomach cancers. The cancer cells travel through your bloodstream or lymphatic system and form new tumors in your liver.
Early detection through blood tests like GGT can help identify liver changes before symptoms appear. Understanding your liver enzyme levels gives you and your care team important information about what is happening inside your body.
Symptoms
- Abdominal pain or discomfort in the upper right side
- Unexplained weight loss and loss of appetite
- Fatigue and weakness that does not improve with rest
- Nausea and vomiting
- Jaundice, which is yellowing of the skin and eyes
- Swelling in the abdomen or legs
- Fever without an obvious cause
- Itchy skin
- Dark urine or pale stools
Many people have no symptoms in the early stages of metastatic liver disease. Liver enzyme changes may show up on blood tests before you feel anything. This is why regular testing is important if you have a history of cancer.

Causes and risk factors
Metastatic liver disease is caused by cancer cells spreading from another organ to the liver. The most common source is colorectal cancer, followed by breast, lung, pancreatic, stomach, and esophageal cancers. Cancer cells break away from the original tumor and travel through blood vessels to the liver. Once there, they attach and begin growing into new tumors.
Risk factors include having any type of cancer, especially in organs that drain blood to the liver through the portal vein. Advanced stage cancers are more likely to spread. Other factors like delayed cancer treatment, certain tumor types, and genetic mutations can increase the risk of metastasis. The liver processes blood from your digestive system, which is why cancers from that area spread there most often.
How it's diagnosed
Doctors diagnose metastatic liver disease using imaging tests like CT scans, MRI, and ultrasound to see tumors in the liver. Blood tests help identify liver function changes and enzyme elevations. GGT is a liver enzyme that often rises earlier than other markers when cancer spreads to the liver. Elevated GGT can signal metastatic disease, biliary obstruction, or liver damage from tumor growth.
Rite Aid offers GGT testing as part of our flagship blood panel, giving you easy access to this important marker. A liver biopsy may be needed to confirm the diagnosis and identify the cancer type. Your doctor will also review your medical history and any previous cancer diagnoses. Early detection through regular blood testing can catch liver changes before symptoms start.

Frequently asked questions
Metastatic liver disease starts as cancer in another organ that spreads to the liver. Primary liver cancer begins in the liver itself. Metastatic liver disease is much more common than primary liver cancer. Treatment approaches differ based on where the cancer originally started.
GGT is a liver enzyme that often rises when cancer spreads to the liver. Tumors can block bile ducts or damage liver tissue, causing GGT levels to increase. Elevated GGT may show up before other liver enzymes change or before symptoms appear. Regular GGT monitoring helps track liver health in people with cancer.
Cure depends on the type of cancer, how much it has spread, and overall health. Some people with limited liver metastases from colorectal cancer can be cured with surgery and chemotherapy. For many, treatment focuses on controlling the cancer and managing symptoms. Advances in targeted therapies and immunotherapy are improving outcomes for many patients.
Colorectal cancer spreads to the liver most often, followed by breast, lung, pancreatic, and stomach cancers. The liver filters blood from the digestive system, which is why colon and rectal cancers reach it easily. Melanoma and certain other cancers can also metastasize to the liver. Any advanced cancer has the potential to spread there.
Testing frequency depends on your cancer type, stage, and treatment plan. Many oncologists recommend liver enzyme checks every 3 to 6 months during active treatment. If you have a history of colorectal or other high-risk cancers, regular monitoring is important even after treatment. Talk to your doctor about the right testing schedule for your situation.
Early on, there may be no symptoms at all. Blood test changes like elevated GGT often appear first. As tumors grow, you might notice fatigue, loss of appetite, or vague abdominal discomfort. Jaundice and significant pain usually appear later. This is why regular blood testing is so important for cancer survivors.
No, elevated GGT can have many causes besides cancer. Alcohol use, certain medications, fatty liver disease, and bile duct problems can all raise GGT. However, in someone with a cancer history, an elevated GGT warrants further investigation. Your doctor will order imaging tests to determine the cause.
Eating small, frequent meals can help when appetite is low. Focus on protein-rich foods to maintain muscle mass. Avoid alcohol completely to reduce liver stress. Gentle exercise like walking can help with fatigue and mood. Stay hydrated and rest when needed.
Good nutrition supports your body during cancer treatment and helps maintain strength. Adequate protein intake is especially important to prevent muscle wasting. Some patients work with oncology dietitians who create specialized meal plans. While nutrition alone cannot cure metastatic disease, it plays an important role in treatment tolerance and quality of life.
Ask how many tumors are in your liver and how large they are. Find out what treatment options are available for your specific situation. Ask about clinical trials that might be appropriate. Discuss how treatment will be monitored and what blood tests will be used to track progress.
