What is Liver Cancer?
Liver cancer is the abnormal growth of cells within the liver tissue, leading to the formation of tumors. These tumors may be primary, originating in the liver itself, or secondary, resulting from the spread of cancer from another organ.
It is considered one of the most dangerous types of cancer due to the delayed onset of symptoms and the difficulty in detecting it in its early stages.
Causes of Liver Cancer
Liver cancer can be caused by several factors, including:
- Chronic infection with hepatitis B or C virus.
- Cirrhosis of the liver resulting from chronic diseases.
- Excessive alcohol consumption over extended periods.
- Obesity and fatty liver disease.
Symptoms of Liver Cancer
Symptoms appear gradually as the disease progresses and include the following:
- Pain or heaviness in the upper right abdomen.
- Loss of appetite and significant weight loss.
- Jaundice (yellowing of the skin and eyes).
- Abdominal swelling due to fluid accumulation.
How is Liver Cancer Diagnosed?
The disease is diagnosed through several medical tests, including:
- Blood test to detect AFP (a tumor marker for the liver).
- Ultrasound or CT scan to detect tumors.
- Magnetic resonance imaging (MRI) to accurately determine the size and location of the tumor.
- Taking a liver tissue sample and examining it under a microscope to confirm the diagnosis.
Treatment for Liver Cancer
Treatment depends on the stage of the disease and the overall condition of the liver. The most important methods include:
- Surgery to remove the tumor or part of the affected liver.
- Liver transplantation in advanced cases.
- Radiation or chemotherapy to reduce the growth of cancer cells.
- Targeted or immunotherapy to improve the body's response to treatment.
When to See a Doctor?
You should see a doctor immediately if you experience persistent abdominal pain, unexplained weight loss, or yellowing of the eyes and skin, especially if you have a history of liver disease or chronic hepatitis.
Tips for Preventing the Disease
Liver cancer can be prevented by following important preventive measures, such as:
- Getting vaccinated against hepatitis B virus.
- Avoiding sharing personal items to prevent hepatitis virus infections.
- Maintaining a healthy weight and eating a balanced diet.
- Abstaining from alcohol and limiting the use of over-the-counter medications.
Frequently Asked Questions
Can a patient with liver cancer be cured?
Yes, it can be cured if detected early, especially if the tumor is small.
Is liver cancer contagious?
No, liver cancer itself is not contagious, but the viruses that cause it, such as hepatitis B and C, can be transmitted from person to person.
Is liver cancer fatal?
It can be fatal in advanced cases if not treated promptly.
Article Summary
Liver cancer is one of the most dangerous types of cancer and often develops as a result of chronic liver diseases.
Early detection, prevention of hepatitis viruses, and avoiding alcohol help reduce the risk of developing the disease and improve the chances of recovery.
