Cancer that starts in our liver is liver cancer. The size of this organ is like of football.
There are many types of liver cancer in which some of them given as:
- Hepatocellular carcinoma
Hepatocellular carcinoma is the most common type of liver cancer. It begins in the hepatocyte that is the main type of liver cells. Other types of liver cancer are less common. Cancers may be metastatic i.e. Some cancers start in areas of the body other than liver and then affect the liver. Examples include colon cancer. Metastatic cancers are more common.
Mostly in the early stages, people have no signs and symptoms of liver cancer. Some symptoms include:
- Loss of weight without any effort
- Lesage of appetite
- Pain in the upper abdomen
- Swelling of abdomen
Stages of liver cancer:
Causes of liver cancer:
In some cases, one cannot know its causes. However, in some cases, one may know the cause. Some causes include:
- Hepatitis virus with infections (chronic)
- Mutations in DNA
These mutations cause to change in the instructions that DNA provides.
- Chronic infections of HBV (Hepatitis B Virus) and HCV (Hepatitis C Virus)
- Cirrhosis (a continual and irreversible process of formation of scar tissue in the liver)
Inherited liver diseases
- Non-alcoholic fatty liver disease (accumulation of fat in the liver)
- More alcohol usage
- Aflatoxins: Some molds grow on those crops, which are stored badly. These molds produce Aflatoxins. This type of contamination is more common in Asia and Africa
- Reduce the consumption of alcohol
- One should have a healthy weight (reduce your healthy weight of 0.5 to 1 kilogram each week until you have a moderate weight)
- Use chemicals with instructions
- Have vaccination against Hepatitis B; it provides 90% protection.
There is no vaccine against hepatitis C. Therefore, one should take preventive measures against hepatitis C.
- Do not use Intravenous (IV) Drugs; it reduces the risk of HCV.
- Use sterile or clean needles
- When you are getting piercing or tattoo, use hygienic shops.
- Liver Cancer Screening:
This does not generally recommend. But The American Association for the Study of Liver Diseases usually recommends this for those who suffer from:
- Hepatitis C
- Liver cirrhosis
- Biliary cirrhosis
- Blood tests:
One can use blood tests for the diagnosis of liver cancer.
- Testing the sample of liver tissue:
One can also use a part of liver tissue. This piece of tissue undergoes from the process of laboratory diagnosis.
- Imaging tests:
Imaging tests include ultrasound, CT scan (computerized tomography) and MRI (Magnetic resonance imaging).
Treatment of liver cancer includes:
Any doctor can use surgery methods if the functions of the liver are good or the size of the liver tumor is small. In this method, the doctor removes the affected area. Doctors can also use liver transplant surgery.
- Heating or freezing cancer cells:
Doctors can also use electric currents to destroy tumors cells. When inserting needles reach the infected area, doctors pass the current through it and destroy tumor cells. During the freezing process, doctors use cryoprobe (an instrument that contains nitrogen in liquid form).
- Radiation Therapy;
Doctors can also use this method for destroying harmful cancerous cells.
