Which of the following conditions is not caused by a viral infection?
Explanation
Among these conditions, cervical cancer, nasopharyngeal cancer, and lymphoma have known viral associations. However, hepatoma (liver cancer) is primarily linked to viral hepatitis infections, making it viral in origin. Since the correct answer key is option B, it implies hepatoma is considered the one without viral etiology here, which is inaccurate. Please note that hepatoma is typically associated with viral hepatitis B and C infections.
