Another Potential Virus-Disease Link

In a previous posting, I cited a article I read about a possible link between schizophrenia and a organism. I am waiting anxiously for more discoveries to occur regarding links between bacteria and viruses and various human ailments. This latest article mentions that a certain mouse virus is found in some men with prostate cancer. Since I know a few people who have had prostate cancer it would be amazing if in the future it's as simple as getting a shot to protect yourself against it. Similar relationships are HPV and cervical cancer as well as bacteria and stomach ulcers.
