One in Six Cancer Worldwide are Caused by Infection

The Lancet Oncology review recently looked at what started some 27 cancers in multiple countries, and came across the conclusion that four main infections (human papillomaviruses, Helicobacter pylori and hepatitis B and C) are are major causes for cervical, gut and liver cancers.
These cases usually happen in the wild. But even so, it does happen in more civilized areas of the world. This is hypothesis-based science, since the scientists and researchers were able to pin point what started certain cancers.
Knowing that some cancers are caused by certain viruses is helpful to the human race because this way, one can vaccinate for those viruses in anticipation, and prevent that cancer. The problem, however, is that these viruses are more common in areas that don't have the vaccinations available. So it makes it easier to prevent getting the viruses in places where the viruses are already less common.
