Causes. Liver cancer happens when liver cells develop changes (mutations) in their DNA. A cell's DNA is the material that provides instructions for every chemical process in your body. DNA mutations cause changes in these instructions. One result is that cells may begin to grow out of control and eventually form a tumor — a mass of cancerous ...
What Causes Liver Cancer? Primary liver cancer (hepatocellular carcinoma) tends to occur in livers damaged by alcohol misuse, or chronic infection with diseases such as hepatitis B and C ...
What is the main cause of liver cancer? Liver cancer happens when something affects healthy liver cells’ DNA. DNA carries the genes that tell our cells how to function.
Cancers can be caused by DNA changes (mutations) that turn on oncogenes or turn off tumor suppressor genes. Several different genes usually need to have changes for a cell to become cancerous. Certain chemicals that cause liver cancer, such as aflatoxins, are known to damage the DNA in liver cells.
Liver cancer causes and risk factors. The most common type of liver cancer in adults, hepatocellular carcinoma (HCC), typically develops in people with chronic (long-lasting) liver disease caused by hepatitis virus infection or cirrhosis. Men are more likely to develop HCC than women. People with multiple risk factors have an even higher risk.
We don't know the precise causes of liver cancer, but risk factors include excessive alcohol use, smoking, liver infections such as hepatitis B and hepatitis C, certain other medical and genetic conditions, and other concerns. Liver cancer can affect both children and adults but occurs most often in adults.
Key points. You can lower your risk of getting liver cancer in several ways. Keep a healthy weight and get enough physical activity. Get vaccinated against hepatitis B and tested for hepatitis C. Avoid drinking too much alcohol. Don't smoke cigarettes. What it is. Liver cancer is a disease in which cells in the liver grow out of control.
Metabolizing fats, carbohydrates and protein. Storing vitamins and minerals from food. Aiding with digestion. Liver cancer begins in the cells of the liver. Some cells may start rapidly dividing and form one or more tumors that interrupt the organ’s function. Liver cancer statistics and facts.
Anyone can get primary liver cancer. It's not always clear what causes it. You might be more likely to get it if you: are over 60 – it's most common in people over 85; are a man; have certain medical conditions, such as hepatitis, liver cirrhosis, gallstones, diabetes, a parasite in the liver (liver flukes) or HIV; have a brother, sister or ...
