Liver Biopsy

This coming November 19, my husband is scheduled to undergo a Liver Biopsy.  At first I was the one eager for him to have it before starting the treatment for Hepatitis C-genotype 3.  My main concern was to know exactly the medical status of his liver as supported with medical test and to know where we are at in this condition but when I became technically aware about the procedure and how will it be done, hesitation arose on my part.
