Hepatocellular Carcinoma

Hepatocellular carcinoma is the most common type of primary liver cancer. It begins in the main cells of the liver, called hepatocytes. This cancer often develops in people who already have long-term liver disease, such as cirrhosis caused by chronic hepatitis or heavy alcohol use.

Hepatocellular carcinoma usually grows slowly at first and may not cause noticeable symptoms in its early stages. As the disease progresses, it can interfere with normal liver function and spread to other parts of the body. Early detection improves treatment options and survival outcomes.

Symptoms

In the early stages, hepatocellular carcinoma may not cause symptoms. As the cancer grows, symptoms may gradually appear.

Common symptoms include:

• Unexplained weight loss

• Loss of appetite

• Upper abdominal pain or discomfort

• Abdominal swelling

• Nausea or vomiting

• Fatigue or weakness

• Yellowing of the skin and eyes

• White or chalky stools

• Easy bruising or bleeding

Symptoms often overlap with those of chronic liver disease, which can delay diagnosis.

Causes

Hepatocellular carcinoma develops when liver cells undergo genetic changes that cause uncontrolled growth.

Common causes include:

• Chronic hepatitis B infection

• Chronic hepatitis C infection

• Liver cirrhosis from any cause

• Long-term heavy alcohol use

• Fatty liver disease related to obesity or diabetes

• Exposure to aflatoxins, which are toxins produced by certain molds

• Inherited liver diseases, such as hemochromatosis

Ongoing liver inflammation and scarring increase the risk of cancerous changes.

Risk factors

Several factors increase the risk of developing hepatocellular carcinoma:

• Chronic hepatitis B or hepatitis C infection

• Cirrhosis of the liver

• Heavy alcohol consumption

• Obesity and type 2 diabetes

• Fatty liver disease

• Male sex

• Older age

• Family history of liver cancer

• Smoking

People with multiple risk factors require regular liver monitoring.

Complications

Hepatocellular carcinoma can cause serious complications, especially as it advances.

Possible complications include:

• Liver failure

• Internal bleeding

• Blockage of bile ducts

• Spread of cancer to lungs or bones

• Severe weight loss and malnutrition

• Reduced response to treatment due to poor liver function

Complications are often life-threatening and require specialized care.

Prevention

Hepatocellular carcinoma may be prevented by reducing the risk of chronic liver disease and detecting liver damage early.

Preventive measures include:

• Vaccination against hepatitis B

• Early testing and treatment for hepatitis B and C

• Limiting alcohol intake

• Maintaining a healthy weight

• Managing diabetes and metabolic conditions

• Avoiding exposure to contaminated food sources

• Regular liver screening for people with cirrhosis or chronic hepatitis

Early prevention and routine surveillance play a key role in lowering the risk of liver cancer and improving long-term outcomes.
