Thank you Stefano for the clarification, something didn't sound right while I was listening to her theory.
My best
As far as I know, it is the X protein (of the HBV) which is responsible for causing liver cancer (HCC).
consider also that doctors and liver specialist are ignorant about hbv.....graduated have the same knowledge of hbv as a baby, i tell this because i happened to hear during a train trip students studying it for an university exam, old views about 5-10 years old about hbv....mostly superficial and wrong
just graduated, too ignorant to understand immune modulators pathways of interferon on hbx protein, the one with main hcc promoting activity, they clear HCC at least liver hcc
antidiabetes drugs or bitter melon may help to get rid of hbx influence (especially antidiabetes drugs show even regression in vitro), interferon beta also clears hbx and blocks HCC development
