I think that there are plenty of other things that are safer to help reduce inflammation in chronic hepatitis patients and thus reduce the risk of liver cancer then Asprin. Asprin has a negative side effect of causing gastritis and thus disrupts your ability to effectively digest your food not to mention can cause intestinal bleeding.

Here is an invitro study looking at a couple of herbs. I bet that if the above study was run looking at the same patients but using a clinically effective dose of curcumin which is a extract of tumeric that there would be even better or equivalent results while also having positive rather then negative side effects.
