A liver biopsy is performed primarily to check for which disease?

• A. Hepatitis B virus
• B. Hepatitis C virus
• C. Hepatitis A virus
• D. Liver cancer

Answer: (B)

A liver biopsy is primarily performed to check for liver damage or disease, particularly in the context of chronic liver diseases such as those caused by the Hepatitis C virus. This virus is known for causing chronic infection that can lead to significant liver inflammation, fibrosis, and ultimately cirrhosis or liver cancer.

During a liver biopsy, a small sample of liver tissue is extracted for histological examination, enabling healthcare providers to assess the degree of liver damage, determine the extent of fibrosis or inflammation, and rule out other conditions. While a biopsy can be used to investigate the effects of other types of hepatitis, such as Hepatitis B, it's most commonly associated with Hepatitis C due to the long-term damage it can cause, making it crucial for diagnosis and treatment planning.

In contrast, Hepatitis A generally causes acute illness rather than chronic disease, which means a liver biopsy is not typically necessary. Liver cancer could be investigated through biopsy, but it is more of a secondary reason to perform the procedure following suspicion from imaging or symptoms rather than a primary reason.
