What is Liver Cancer? Symptoms, Causes, & Treatment

Liver cancer happens when abnormal cells in your liver grow out of control and form tumors. Your liver, one of your body's largest organs, sits in the upper right part of your abdomen and works hard to filter toxins, produce proteins, and help with digestion.

There are two main types of liver cancer. Primary liver cancer starts in the liver itself, while secondary liver cancer spreads to the liver from other parts of your body. Understanding the difference helps doctors choose the right treatment approach for your specific situation.

What are the symptoms of liver cancer?

Early liver cancer often doesn't cause noticeable symptoms, which is why it's sometimes called a "silent" disease. When symptoms do appear, they can feel vague and similar to other common health issues.

Here are the symptoms you might experience as liver cancer progresses:

• Unexplained weight loss without trying to lose weight
• Loss of appetite or feeling full after eating small amounts
• Upper abdominal pain or discomfort, especially on the right side
• Swelling in your abdomen from fluid buildup
• Yellowing of your skin and eyes (jaundice)
• Unusual fatigue that doesn't improve with rest
• Nausea and vomiting
• White or chalky-colored stools

Some people also notice their urine becoming darker than usual. These symptoms can develop gradually over weeks or months. Remember, having these symptoms doesn't automatically mean you have liver cancer, as many other conditions can cause similar feelings.

What are the types of liver cancer?

Primary liver cancer starts in your liver and comes in several forms. The most common type is hepatocellular carcinoma, which accounts for about 80% of all primary liver cancers.

Hepatocellular carcinoma typically develops in people who already have liver disease or cirrhosis. It often grows slowly at first but can spread to other parts of your liver or body over time.

Other less common types include cholangiocarcinoma, which starts in the bile ducts inside your liver. This type is rarer but can be more challenging to treat because it's often discovered later.

Secondary liver cancer, also called metastatic liver cancer, is actually more common than primary liver cancer. This happens when cancer from another part of your body spreads to your liver through your bloodstream or lymphatic system.

What causes liver cancer?

Liver cancer develops when the DNA in liver cells becomes damaged, causing them to grow uncontrollably. This damage can happen for several reasons, and understanding these causes can help you make informed decisions about your health.

The most common causes include:

• Chronic hepatitis B or hepatitis C infections
• Cirrhosis from long-term alcohol use
• Non-alcoholic fatty liver disease
• Exposure to aflatoxins (toxins from moldy grains or nuts)
• Certain inherited liver diseases like Wilson's disease
• Diabetes, especially when combined with other liver conditions
• Obesity and metabolic syndrome

Some rare causes include exposure to certain chemicals like vinyl chloride or thorium dioxide. Anabolic steroids used long-term can also increase your risk, though this is uncommon.

Having one of these risk factors doesn't mean you'll definitely develop liver cancer. Many people with these conditions never develop cancer, while others without obvious risk factors sometimes do.

When to see a doctor for liver cancer?

You should contact your doctor if you experience persistent symptoms that worry you, especially if they last more than a few weeks. Early detection can make a significant difference in treatment outcomes.

Seek medical attention promptly if you notice yellowing of your skin or eyes, as this could indicate a serious liver problem that needs immediate evaluation. Severe abdominal pain or sudden swelling in your belly also warrant quick medical assessment.

If you have risk factors like chronic hepatitis or cirrhosis, regular check-ups with your doctor become even more important. They can monitor your liver health and catch any changes early.

What are the risk factors for liver cancer?

Several factors can increase your chances of developing liver cancer, though having risk factors doesn't guarantee you'll get the disease. Understanding these factors helps you and your doctor make the best decisions for your health.

The most significant risk factors include:

• Chronic hepatitis B or C infection
• Cirrhosis from any cause
• Heavy alcohol consumption over many years
• Non-alcoholic fatty liver disease
• Diabetes
• Obesity
• Family history of liver cancer
• Being male (men are more likely to develop liver cancer)
• Age over 60

Some less common risk factors include certain genetic conditions like hemochromatosis, which causes your body to absorb too much iron. Primary biliary cholangitis and alpha-1 antitrypsin deficiency are other rare genetic conditions that can increase risk.

Geographic factors also play a role. Liver cancer rates are higher in parts of Asia and Africa where hepatitis B infections are more common.

What are the possible complications of liver cancer?

Liver cancer can lead to several serious complications as it progresses, affecting both your liver function and overall health. Understanding these possibilities helps you and your medical team prepare and respond appropriately.

Common complications include:

• Liver failure as cancer cells replace healthy liver tissue
• Fluid buildup in your abdomen (ascites)
• Bleeding from enlarged blood vessels in your esophagus
• Confusion or altered mental state from toxin buildup
• Kidney problems
• Spread of cancer to other organs

Some people develop portal hypertension, which happens when blood flow through the liver becomes blocked. This can cause dangerous bleeding and requires immediate medical attention.

Rare complications include blood clots in the liver's blood vessels or severe infections. Your medical team will monitor you closely to catch and treat any complications early.

How can liver cancer be prevented?

While you can't prevent all cases of liver cancer, you can take meaningful steps to reduce your risk significantly. Many prevention strategies focus on protecting your liver from damage that could lead to cancer.

The most effective prevention steps include getting vaccinated against hepatitis B if you haven't already. This vaccine is highly effective and can prevent one of the leading causes of liver cancer worldwide.

Limiting alcohol consumption protects your liver from cirrhosis, which greatly increases cancer risk. If you drink alcohol, try to stay within recommended limits or consider avoiding it altogether if you have other liver risk factors.

Maintaining a healthy weight through regular exercise and a balanced diet helps prevent fatty liver disease. Focus on eating plenty of fruits, vegetables, and whole grains while limiting processed foods and added sugars.

If you have hepatitis B or C, work closely with your doctor to manage the infection with antiviral medications. These treatments can significantly reduce your risk of developing liver cancer.

How is liver cancer diagnosed?

Diagnosing liver cancer typically involves several tests that help your doctor see what's happening inside your liver. The process usually starts with blood tests and imaging studies to get a clear picture.

Your doctor will likely begin with blood tests to check your liver function and look for tumor markers like alpha-fetoprotein (AFP). Elevated AFP levels can suggest liver cancer, though not everyone with liver cancer has high levels.

Imaging tests like CT scans, MRI, or ultrasound help doctors see the size, location, and number of tumors in your liver. These tests are painless and provide detailed pictures of your liver structure.

Sometimes a liver biopsy is needed to confirm the diagnosis. During this procedure, your doctor removes a small sample of liver tissue to examine under a microscope. This gives the most definitive answer about whether cancer cells are present.

In some cases, doctors can diagnose liver cancer based on imaging alone, especially if you have cirrhosis and the tumor has characteristic features on scans.

What is the treatment for liver cancer?

Treatment for liver cancer depends on several factors, including the size and location of tumors, how well your liver is functioning, and your overall health. Your medical team will work with you to create a personalized treatment plan.

Surgery offers the best chance for a cure when the cancer is caught early and hasn't spread. Options include removing part of your liver (partial hepatectomy) or, in some cases, liver transplantation.

For tumors that can't be surgically removed, several other treatments can help control the cancer and improve quality of life:

• Ablation therapy destroys cancer cells using heat, cold, or alcohol
• Embolization blocks blood flow to tumors
• Radiation therapy targets cancer cells with high-energy beams
• Targeted drug therapy attacks specific cancer cell features
• Immunotherapy helps your immune system fight cancer
• Chemotherapy, though less commonly used for liver cancer

Some people benefit from combining treatments. For example, you might have ablation therapy followed by targeted drugs, or surgery combined with chemotherapy.

Palliative care focuses on managing symptoms and improving comfort when curative treatment isn't possible. This specialized medical care can significantly enhance your quality of life throughout treatment.

How to manage liver cancer at home?

Taking care of yourself at home plays an important role in your overall treatment plan. Simple changes in your daily routine can help you feel better and support your medical treatments.

Eating well becomes especially important when you have liver cancer. Focus on getting enough protein to help your body stay strong, and try eating smaller, more frequent meals if you feel full quickly.

Stay hydrated by drinking plenty of water throughout the day. Avoid alcohol completely, as it can further damage your liver even in small amounts.

Gentle exercise like walking can help maintain your strength and energy levels. Listen to your body and rest when you need to, but try to stay as active as possible within your comfort level.

Keep track of your symptoms and any changes you notice. This information helps your medical team adjust your treatment plan as needed.

How should you prepare for your doctor appointment?

Preparing for your doctor visits helps you make the most of your time together and ensures you get the information you need. A little preparation can make these appointments more productive and less stressful.

Write down all your symptoms, including when they started and how they've changed over time. Include details about pain levels, appetite changes, and any other concerns you've noticed.

Bring a complete list of all medications, supplements, and vitamins you're taking. Include the dosages and how often you take them, as some substances can affect your liver.

Prepare a list of questions you want to ask your doctor. Don't worry about asking too many questions - your medical team wants to help you understand your condition and treatment options.

Consider bringing a family member or friend to your appointments. They can help you remember important information and provide emotional support during difficult conversations.

What's the key takeaway about liver cancer?

Liver cancer is a serious condition, but understanding it empowers you to make informed decisions about your health. Early detection and treatment significantly improve outcomes, which is why paying attention to symptoms and risk factors matters.

Remember that having risk factors doesn't mean you'll definitely develop liver cancer, and many effective treatments are available. Your medical team is your best resource for personalized advice and care.

Focus on what you can control - maintaining a healthy lifestyle, following your treatment plan, and staying connected with your healthcare providers. Each person's journey with liver cancer is unique, and hope remains an important part of the healing process.
