New Screening Method May Identify Tumor Viruses

For the first time, a new screening method shows promise for identifying new human tumor viruses, as well as determining which cancers are caused by infection and which are not. Statistics now show that infection contributes to over 20% of human cancers worldwide. Presently, the list of confirmed carcinogenic infectious agents is short, however studies suggest that new infectious agents yet to be identified contribute to a wide range of diseases, including cancers.
