My girlfriend's father was cured a few years ago using an experimental biotech therapy at Stanford University. He had "terminal" liver cancer at the time caused by the HepC, which incidentally was cured by another experimental therapy at the same time. He was the perfect guinea pig; he was terminal with only a couple months to live and had two incurable diseases, so they could try some exotic stuff that they normally wouldn't use on a healthy human. Two-for-two is either phenomenally lucky for experimental medicine, or our technology is getting better fast.
Anyway, there is hope. The woman's father is perfectly healthy today a few years later, with neither a trace of HepC nor liver cancer.
