Cellular terrain, toxins, food and cancer
As you know, diseases such as cancer are mostly all about terrain and what is introduced into the terrain. That is why industrialized countries have seen such an increase in cancer - the toxic chemicals and the crap food we have, along with increased radiation exposure.
Granted, there are cancers in less develped countries too - but what do those countries often have in common? Poor nutrition and thus unhealthy cellular terrain and immune systems. Where you find less chemicals and plenty of good nutrient dense unadulterated food you find much lower incidence of cancer.
Have you ever noted how many of the chemical and food companies are behind cancer programs which direct attention and research away from toxins, toxic products, additives and crap foods such as those they produce?
See for example:

While there certainly are viruses that can produce cancer and many viruses which have been assoiciated with increased incidence of cancer, I believe that in many instances it is the damage caused by viruses which leads to cancers which are associated with viruses - especially when those viruses are introduced into cellular terrain which is already compromised. Another way of looking at it is that when immune systems are not strong enough to beat back viruses they often are also not strong enough to beat back cancer and other illness - so naturally there would be an association between viruses and increased cancer incidence.
If there truly were compelling evidence that viruses cause most cancers, don't you think that vaccination-loving Big Pharma and mainstream medicine would be jumping all over the connection in order to produce a whole plethora of new anti-cancer vaccines? One can only shudder, given the horrors the HPV vaccine has produced.
