Frequent question: How does hepatitis B and C cause cancer?

How does Hep C cause cancer?

About 30 percent of people who get exposed to the hepatitis C virus will clear it on their own. The rest will go on to have chronic hepatitis C. This ongoing infection causes inflammation in the liver. This extended inflammation can cause scarring, called cirrhosis, and can ultimately lead to liver cancer.

Does Hep B or C cause cancer?

People who are infected with hepatitis B virus (HBV) or hepatitis C (HCV) virus may develop a chronic infection that can lead to cirrhosis. The damage that results increases the risk of liver cancer (hepatocellular carcinoma).

What cancers are caused by hepatitis B?

Chronic HBV infection can lead to chronic hepatitis, liver cirrhosis, and hepatocellular carcinoma (HCC). HCC is one of the five major cancers in the world population. Hepatitis B virus (HBV) is the most important etiologic agent of liver cancer globally, particularly in high-prevalence areas of liver cancer.

Does hepatitis B always lead to cancer?

Individuals chronically infected with hepatitis B have a 25% to 40% lifetime risk of developing liver cancer. In the United States, chronic infection with the hepatitis C virus is the leading cause of liver cancer because of the greater number of Americans infected with this virus.

What does hep C pain feel like?

Many chronic HCV sufferers also complain of getting aches and pains. Large numbers get sharp pains over the liver (found in the upper right corner of the abdomen) which can sometimes be very alarming. These pains are not necessarily connected with severe liver disease.

How long does it take for Hep C to damage your liver?

After many years some people will have minimal liver damage with no scarring while others can progress to cirrhosis (extensive scarring of the liver) within less than ten years. On average it takes about twenty years for significant liver scarring to develop.

Can you survive liver cancer if caught early?

For people with early-stage liver cancers who have a liver transplant, the 5-year survival rate is in the range of 60% to 70%.

5-year relative survival rates for liver cancer.

SEER stage 5-year relative survival rate
Regional 12%
Distant 3%
All SEER stages combined 20%

What are the warning signs of liver cancer?

Some of the most common symptoms of liver cancer are:

  • Weight loss (without trying)
  • Loss of appetite.
  • Feeling very full after a small meal.
  • Nausea or vomiting.
  • An enlarged liver, felt as fullness under the ribs on the right side.
  • An enlarged spleen, felt as fullness under the ribs on the left side.

What are the chances of surviving hepatitis B?

The estimated 5-year survival rates were 97% for patients with chronic persistent hepatitis, 86% for those with chronic active hepatitis, and 55% for those with chronic active hepatitis with cirrhosis. The usual cause of death was liver failure and its sequelae.
