Why Do Common Viruses Rarely Become Cancer?

This documentary investigates why infection with a human oncogenic virus does not automatically lead to cancer. It examines the viruses associated with human malignancies and the roles of host factors, tissue context, immune status, and cellular processes. The film examines what researchers know about viral carcinogenesis, biomarkers, and treatment resistance—and what remains unanswered about why cancer develops in particular circumstances.
