What Is Liver Cancer?: Types, Causes, Stages amd Treatment
Written by Medicover Team and Medically Reviewed by Dr S K Azharuddin , Oncologist
Liver cancer is a serious illness that starts when abnormal cells begin to grow uncontrollably in the liver. The liver is your body's largest internal organ and plays a crucial role in keeping you healthy, it helps digest food, stores energy, filters out toxins, and supports your immune system. Because the liver is essential for life, any damage to it can become life-threatening if not treated in time.
There are two main types of liver cancer:
- Primary liver cancer: Begins in the liver itself.
- Secondary (metastatic) liver cancer: Spreads to the liver from another part of the body (like the lungs, breast, or colon).
What arew the Stages of Liver Cancer?
Liver cancer is classified into stages to describe how far the disease has progressed. Staging assists doctors both in assessing the size of the tumor and whether it has spread to surrounding tissues and organs as well as in choosing the most effective treatment. Understanding the various stages is important for prognosis and for individualizing care to each patient state.
Doctors utilise the Barcelona Clinic Liver Cancer (BCLC) staging system which takes into account:
- Size and number of tumors
- Liver function
- Overall health
- Cancer spread
Liver Cancer Stages
Stage 0/Stage I (Very Early)
- Single tumor less than 2 cm
- No symptoms, normal liver function
Stage A/Stage II (Early)
- Single tumor leaas than 5 cm or multiple small tumors
- Liver function is preserved
Stage B/Stage III (Intermediate)
- Several tumors in the liver
- No spread beyond the liver
Stage C/Stage IV (Advanced)
- Cancer has spread to blood vessels, lymph nodes, or other organs
Stage D/Stage V (End Stage)
- Severely damaged liver
- Advanced symptoms
- Limited treatment options
What Are the Different Types of Primary Liver Cancer?
Primary liver cancer originates from different cell types within the liver. Knowing the type is important for diagnosis, treatment, and prognosis. The main types include:
- Hepatocellular Carcinoma (HCC): The most common type, accounting for nearly 75% of cases. It begins in hepatocytes, the main liver cells, often seen in people with chronic hepatitis or cirrhosis.
- Intrahepatic Cholangiocarcinoma (IHC): Also called bile duct cancer, it originates in the bile ducts inside the liver and makes up about 10-20% of cases.
- Hepatoblastoma: A rare liver cancer mostly seen in children under 3 years old. It is highly treatable when detected early.
- Hepatic Angiosarcoma: A very rare, fast-growing cancer starting in the liver's blood vessels, often diagnosed late.
Liver Cancer Causes and Risk Factors
Liver cancer occurs when liver cells develop mutations in their DNA,leading to uncontrolled growth and tumor formation. While the exact cause may be unclear in some people, certain factors are known to increase risk.

Get Second OpinionRisk Factors for Liver Cancer
Chronic Liver Infections
- Hepatitis B (HBV) and Hepatitis C (HCV) infections are the leading risk factors
- Long-term infection leads to liver inflammation, cirrhosis, and eventually cancer
Cirrhosis
- A condition where healthy liver tissue is replaced by scar tissue
- Causes include alcohol abuse, hepatitis infections, and nonalcoholic fatty liver disease (NAFLD)
Genetic or Inherited Conditions
- Hemochromatosis, excess iron in the body
- Wilson's disease, copper buildup in organs
- Alpha-1 antitrypsin deficiency
- Tyrosinemia
Lifestyle and Environmental Risks
- Heavy alcohol consumption
- Smoking tobacco
- Obesity and Type 2 diabetes
- Exposure to aflatoxins (toxins from moldy grains/nuts)
- Anabolic steroids used for bodybuilding
- Prolonged exposure to industrial chemicals (e.g., vinyl chloride)
What are the Liver Cancer Symptoms and Warning Signs?
Liver cancer often develops silently in its early stages, with few or no noticeable symptoms. As the disease progresses, various signs may appear, reflecting the liver's declining ability to function properly.
Being aware of these symptoms can help in early detection and prompt medical intervention, which can improve outcomes. Symptoms may include:
- Unexplained weight loss
- Loss of appetite
- Persistent fatigue or weakness
- Nausea or vomiting
- Pain in the upper right abdomen
- Swollen or bloated abdomen
- A hard lump under the right ribcage
- Jaundice-yellowing of the skin and eyes
- Dark urine and pale or white stools
- Fever
- Itchy skin
- Easy bruising or bleeding
How Is Liver Cancer Diagnosed?
Diagnosing liver cancer usually involves a physical exam, blood tests, imaging scans, and in some cases, a biopsy. Since early-stage liver cancer often doesn't cause noticeable symptoms, these tests are important to catch the disease early and figure out how advanced it is. Early detection helps doctors decide on the most effective treatment plan.
The various tests to diagnose liver cancer are as follows:
- Blood test: It includes liver function tests (LFT) that gives information about the state of the liver. Serum AFP level estimation, Viral screening such as HBsAg and HCV testing are important tests.
- Ultrasound scan: The ultrasound scan or USG scan uses high-frequency sound waves to generate images of the internal body structures of the body. This scan can help to know liver abnormalities.
- Computed tomography or CT scan: A CT scan is a x-rays test is used to determine if liver cancer has spread to other organs of the body.
- Magnetic resonance imaging (MRI): MRI scans are useful to inspect liver tumours. At times they can differentiate between a benign tumour from a malignant one. An MRI scan can examine blockages in the blood vessels surrounding the liver, and to diagnose liver metastases.
- Liver biopsy: A small tissue sample is removed and tested for cancer cells, making this the most accurate way to confirm a diagnosis.
Liver Cancer Treatment Options
The treatment for liver cancer varies depending on a number of factors including the stage of the cancer, a patient's overall health and liver function. Options may range from surgery and liver transplantation to targeted therapy, immunotherapy, and other minimally invasive procedures.
A personalized treatment plan is essential to manage the disease effectively and improve quality of life.
Medical (Non-Surgical) Treatments
Targeted Therapy
- Blocks specific proteins that help cancer grow
- Example: Sorafenib, Lenvatinib
Immunotherapy
- Stimulates your immune system to fight cancer cells
- Example: Atezolizumab + Bevacizumab
Chemotherapy
- Uses drugs to kill fast-growing cells
- Less commonly used for liver cancer than other cancers
Chemoembolization (TACE)
- Delivers chemotherapy directly to the liver tumor
- Blocks blood supply to starve the tumor
Radioembolization (TARE)
- Injects radioactive beads into liver blood vessels
Radiation Therapy
- Uses high-energy beams to kill cancer cells
- Especially helpful for pain relief or when surgery isn't possible
Surgical Treatments
Liver Resection (Hepatectomy)
- Removes part of the liver containing the tumor
- Best for patients with good liver function and small tumors
Liver Transplant
- Entire liver is replaced with a healthy donor liver
- Ideal for those with multiple small tumors and damaged liver
Ablation Therapies
- Radiofrequency ablation (RFA) or Microwave ablation (MWA)
- Use heat or cold to destroy cancer cells without removing them
When to visit a doctor for Liver Cancer?
Liver cancer may not cause symptoms in its early stages, but catching it early makes treatment more effective. It often develops in people with liver diseases like hepatitis B, hepatitis C, or cirrhosis.
See a doctor if you notice:
- Pain or discomfort in the upper right side of the belly
- Unexplained weight loss or loss of appetite
- Feeling full after eating a small amount
- Yellowing of the skin or eyes (jaundice)
- Ongoing fatigue or weakness
- Swelling in the belly
You should get checked especially if:
- You have a history of liver disease, alcohol use, or hepatitis
- You've been diagnosed with fatty liver or cirrhosis
- You are in a high-risk group (such as people with chronic hepatitis B or C)
Early medical advice can help detect liver cancer early and begin treatment quickly.
