BIMARIDUR HEALTH ENCYCLOPEDIA

Liver Cancer

Liver cancer is cancer that begins in the liver. The main types of primary adult liver cancer are hepatocellular carcinoma and intrahepatic bile duct cancer.

ICDC22.0
Affected areaLiver and, in advanced disease, nearby lymph nodes, blood vessels, lungs, bones, adrenal glands or other organs.
ContagiousnessLiver cancer itself is not contagious. However, hepatitis B and hepatitis C infections, which can increase liver-cancer risk, can be transmitted between people.
01 • QUICK UNDERSTANDING

What is Liver Cancer?

Primary liver cancer most commonly occurs as hepatocellular carcinoma. Risk is strongly associated with chronic liver disease, especially hepatitis B, hepatitis C and cirrhosis. Treatment depends on tumor extent, liver function and overall health.

02 • BODY & MECHANISM

What happens in the body?

Body structure involved

The liver is the largest internal organ and lies mainly in the upper right abdomen beneath the diaphragm. It has right and left lobes and performs major metabolic, detoxification, digestive and protein-production functions.

How it starts

Primary liver cancer develops when liver or bile-duct cells acquire changes that disrupt normal growth. Chronic inflammation, fibrosis and cirrhosis can create an environment that increases the risk of malignant transformation.

What happens inside the body

Abnormal liver cells acquire genetic changes that allow uncontrolled growth and survival. A tumor may remain within the liver, invade blood vessels or spread to other parts of the body.

03 • TYPES & CLASSIFICATION

Types and classification

Primary adult liver cancers include hepatocellular carcinoma, which arises from hepatocytes, and intrahepatic cholangiocarcinoma, which arises from bile-duct cells. Other rare primary liver tumors also exist.

The main adult primary liver cancers are hepatocellular carcinoma and intrahepatic cholangiocarcinoma. Less common tumors include hepatic angiosarcoma and other rare cancers.

04 • SYMPTOMS

Symptoms and warning signs

Jaundice

Unexplained weight loss

Right-upper-abdominal discomfort

Abdominal swelling

Loss of appetite

Unusual fatigue or weakness

Nausea or vomiting

Easy bruising or bleeding

Dark urine

Pale or chalky stools

Fever

Feeling full after eating a small amount

05 • LESS OBVIOUS SIGNS

Signs that may be easy to miss

Early liver cancer may cause few or no symptoms and may be detected during surveillance imaging in people with chronic liver disease.

06 • CAUSES

What can cause this disease?

Risk factors include chronic hepatitis B or C infection, cirrhosis, heavy alcohol exposure, metabolic liver disease, aflatoxin exposure, smoking and certain inherited disorders.

07 • RISK FACTORS

Who may have a higher risk?

1

Chronic hepatitis B

2

Chronic hepatitis C

3

Cirrhosis

4

Heavy alcohol use

5

Obesity and metabolic disease

6

Type 2 diabetes

7

Aflatoxin exposure

8

Smoking

9

Family or inherited liver disorders

08 • DIAGNOSIS

How is Liver Cancer diagnosed?

Evaluation may include physical examination, liver-function tests, AFP testing, ultrasound, multiphasic CT or MRI and additional imaging. Biopsy is used selectively when imaging does not establish the diagnosis or another tumor type is suspected.

Clinical evaluation

Examination for jaundice

Abdominal examination for liver enlargement or mass

Assessment for abdominal fluid accumulation

Assessment for weight loss

Assessment for bruising or bleeding

Review of chronic liver disease history

Assessment of liver-function status

Review of hepatitis B and hepatitis C history

Laboratory tests

Liver function tests

Alpha-fetoprotein

Complete blood count

Serum bilirubin

Albumin

Prothrombin time or INR

Kidney function tests

Hepatitis B testing

Hepatitis C testing

Imaging and scans

Liver ultrasound

Multiphasic contrast-enhanced CT

Contrast-enhanced MRI of the liver

Chest imaging when staging requires it

Additional imaging for suspected metastatic disease

Special or confirmatory tests

Image-guided liver biopsy when required

Assessment of portal-vein or hepatic-vein invasion

Assessment of liver reserve and cirrhosis severity

Genetic or molecular testing in selected tumor types

Multidisciplinary liver-cancer assessment

09 • DIFFERENTIAL CONTEXT

Conditions that may look similar

Liver abscess

Metastatic cancer to the liver

Regenerative or dysplastic nodules in cirrhosis

10 • EXTENT / STAGE

Stages or severity

Liver cancer staging considers tumor burden, vascular invasion, spread outside the liver, liver function and overall health. The Barcelona Clinic Liver Cancer system commonly describes very early, early, intermediate, advanced and end-stage disease.

Important:

Staging or grading systems differ between diseases. The information here is educational and should be interpreted by a qualified healthcare professional in the context of the individual case.

11 • TREATMENT

How is Liver Cancer treated?

Treatment can include surveillance of selected very small lesions, surgical resection, liver transplantation, tumor ablation, radiation therapy, transarterial treatments such as TACE and systemic therapy for advanced disease. Treatment is individualized according to tumor stage and liver function.

Medicines that may be used

Systemic immunotherapy for selected advanced hepatocellular carcinoma

Targeted therapy for selected advanced hepatocellular carcinoma

Antiviral treatment for chronic hepatitis B or C when indicated

Pain-control medicines

Medicines for symptoms or complications of chronic liver disease

Supportive and palliative medicines when appropriate

Medicine safety:

Medicines listed here are for educational information only. Do not start, stop, or change a medicine without professional medical advice.

12 • COMPLICATIONS

Possible complications

Complications can include liver failure, jaundice, ascites, gastrointestinal bleeding, cancer-related pain, blood-vessel invasion, cancer spread and complications from treatment.

URGENT SAFETY INFORMATION

When should urgent medical help be considered?

Vomiting blood or passing black, tarry stools

Severe abdominal swelling with breathing difficulty

Confusion or marked drowsiness

Severe jaundice with rapid deterioration

Fainting or severe weakness

Severe abdominal pain

Sudden neurological symptoms or severe breathing difficulty

If symptoms are severe, rapidly worsening, or life-threatening, seek emergency medical care immediately.

13 • OUTLOOK

Prognosis and recovery outlook

Earlier detection can provide potentially curative treatment options. Prognosis is influenced by cancer stage, liver function, cirrhosis, general health and treatment response.

How to interpret these statistics

Survival statistics describe outcomes in groups of people and cannot predict exactly what will happen to one individual. Prognosis depends on factors such as cancer stage, tumor biology, treatment response, overall health, and follow-up.

14 • EPIDEMIOLOGY

How common is it?

Primary liver cancer is an important global cancer. Hepatocellular carcinoma is the most common adult primary liver cancer, and chronic hepatitis B and C and cirrhosis are major risk factors.

15 • PREVENTION

Risk reduction and prevention

Hepatitis B vaccination, prevention and treatment of viral hepatitis, reducing harmful alcohol exposure, maintaining a healthy weight, controlling metabolic disease and avoiding tobacco can reduce liver-cancer risk.
