A New theory that how viruses contribute for Cancer

A new study suggests that viruses may contribute to cancer by causing excessive death to normal cells while promoting the growth of surviving cells with cancerous traits. Viruses may act as forces of natural selection by wiping out normal cells that support the replication of viruses and leaving behind those cells that have acquired defects in their circuitry. When this process is repeated over and over, cancer can develop say study authors, led by Preet M. Chaudhary, M.D., Ph.D., professor of medicine at the University of Pittsburgh School of Medicine. Their findings are published by Public Library of Science in the Oct. 24 issue of PLoS ONE.
Infection with viruses has been linked to many human cancers, including some forms of Hodgkin’s and non-Hodgkin’s lymphomas, sarcomas and cancers of the throat and liver. Over the years, scientists have proposed a number of mechanisms to explain this link. One commonly held belief is that when a virus infects a cell, its genetic material alters the cell, making it grow uncontrollably, eventually leading to cancer. Some viruses also are thought to promote cancer by causing chronic inflammation. In his study, it is proposes that viruses also can lead to cancer in a less direct manner.

Thanks Aftab for posting this information,
that is excellent news. Did they prove this by experimentation or was it a review of years of works?

thanks

I'd like to add this great link to a Virology chapter on Oncogenic Viruses ---> [Only registered users see links. ]
