Liver biopsy is a medical procedure in which a doctor uses a special needle to remove a small piece of tissue from your liver to check for signs of damage. A liver biopsy will help you and your doctor find out more about the health of your liver.
This is important if you have hepatitis C or another liver disease and you are trying to decide about treatment. A liver biopsy also can be helpful if your doctor is not sure what is causing your liver problem. Not everyone, however, will need a liver biopsy.
