My son was diagnoised with chronic Hep B. He had it for 12yrs. before we found out, Drs. say it is biochemical , meaning that he got it from chemo radiation or blood transfusions as he had AML leukemia as a baby 16 mths old. As of Aug. 31, 07 he now has cirrhosis of the liver! He's 21 and a fighter for life!
