Cancer: but what if it were a disease caused by an association between microorganisms?
This article makes an analogy and compares the biological behavior of bacteria, viruses and neoplasms, showing several common points in their mechanisms of growth and survival, questioning cancer as a distinct living organism and introducing the hypothesis of synergy between viruses and bacteria in the development of neoplasms. Up to now, there are no experimental studies that effectively investigate the association between more than one microorganism as an etiologic factor of cancer.RESUMO Apesar dos avan ços no conhecimento do comportamento das neoplasias, o entendimento exato dos processos biológicos que envolvem os t...
