Re: My two cents

As a matter of fact yes. As an example the Rous sarcoma virus, the first cancer virus ever identified, was found to be airborne transmitted. So why don't we see epidemics or pandemics of cancer? Simple, the immune system has to be sufficiently suppressed to allow the viruses to take hold. Why do AIDS patients develop cancers from the same exact viruses that most people harbor but don't cause cancers in those healthy individuals? For example Epstein Barre Virus (EBV), which infects the majority of the population. EBV has been proven to cause B cell lymphoma as evidenced by "David the bubble boy". In order for a virus to be "active" in the body the immune system must be sufficiently suppressed to allow the virus to become active. Why do people with herpes infections only get outbreaks when under a lot of stress or are affected by other immune suppressants? Because stress, and other immune suppressants like stimulants and steroids, weaken the immune system sufficiently to allow the viruses to take hold.

Hepatitis viruses can be transmitted, and they have been shown to cause cancer. Human papilloma virus (HPV) causes a host of cancers, and it is also transmittable. And Helicobacter pylori bacteria has been implicated in stomach cancer, and it has been shown to be transmissible as well. So why are we not all dying from cancer? Because not everyone has immune systems suppressed enough to allow these microbes to take a good hold.
