Overview
Liver cancer begins in the cells of your liver. Metastatic cancer — that is, cancer that starts in another area of the body and spreads to the liver — is more common than cancer that begins in the liver itself.
Types of Liver Cancer
1. Benign Liver Tumors
These tumors do not grow into nearby tissues and do not spread to distant sites.
2. Primary Liver Cancer
This type of cancer starts within the liver itself and is often referred to as hepatocellular carcinoma (HCC).
3. Secondary (Metastatic) Liver Cancer
It begins in another area of the body and spreads to the liver through the bloodstream or lymphatic system.
Causes of Liver Cancer
- Cirrhosis: Scar tissue replaces healthy liver cells due to alcohol abuse or chronic damage.
- Chronic Hepatitis B or C: Long-term infection can lead to cirrhosis and liver cancer.
- Fatty Liver Disease: Caused by excessive fat buildup in liver cells.
- Tobacco Use: Smoking increases the risk of liver cancer.
- Type 2 Diabetes: Often linked with obesity and fatty liver disease.
- Hemochromatosis: A condition causing excess iron accumulation in the liver, which may lead to cirrhosis or cancer.
Symptoms of Liver Cancer
- Unintended weight loss
- Jaundice (yellowing of skin or eyes)
- Enlarged liver or spleen
- Abdominal pain or swelling
- Nausea or vomiting
- Loss of appetite
- Fluid buildup in the abdomen
- General weakness or fatigue
Prevention of Liver Cancer
- Maintain a healthy weight
- Avoid smoking and excessive alcohol consumption
- Get timely treatment for Hepatitis B and C
- Eat a balanced diet with sufficient protein
Diagnosis of Liver Cancer
- Blood Tests: To check liver function and detect abnormalities.
- Imaging Tests: Ultrasound, CT scans, or MRIs help visualize the liver and detect tumors.
- Biopsy: A small sample of liver tissue is examined in a lab to confirm cancer diagnosis.
Treatment of Liver Cancer
Surgery: Removal of cancerous tissue or a liver transplant in early-stage cases.
Cryoablation: Freezing liver tumors with liquid nitrogen to destroy cancer cells.
Radiofrequency Ablation: Using electric current to heat and destroy tumor cells through inserted needles.
Immunotherapy: Strengthening the body’s immune system to fight cancer.
Radiation Therapy: High-energy X-rays or protons are used to target and kill cancer cells.
Targeted Therapy: Specialized drugs target tumor cells with minimal harm to normal tissue.
Chemotherapy: Drugs that stop cancer growth by killing cells or preventing division, administered orally or intravenously.
Takeaway
Liver cancer can be managed effectively with early detection and proper medical care. Understanding its causes, symptoms, and treatments empowers individuals to take timely action.
Regular checkups, healthy habits, and preventive measures are key to reducing the risk and improving recovery outcomes.
