This is an article from an internal publicity publication by the medical school that is doing the research, so it's a bit more thorough than a press release, but no more skeptical. It may be that the Stanford Cancer Institute is doing great research on cancer that will bring us a cure for many cancers during our lifetime, but the stage of research on mice reported in this article must still be followed by carrying out "plans to begin human clinical trials of the therapy in late 2013 or early 2014." I hope this all works out, but we'll have to check back for more news about the safety and effectiveness of the treatment in human subjects later.
I agree, but having already encountered cancer in the family, I'm going to keep a close eye on this development with hope that it leads to a cure.
I always operate extreme skepticism when looking at cancer stories as there are so many potential motivations for their publication. I try to ignore them unless their is published research that has been interdependently replicated. Even when their is confirmed new research the chances of it developing into practical treatment are small and even smaller that it will make a significant dent in survival rates.
