The majority of cancers is caused by viral infection, and Peyton Rous won a Nobel Prize for this discovery.Group of answer choicesTrueFalse

The statement is False.

While certain viruses are known to be associated with some types of cancer (such as human papillomavirus (HPV) with cervical cancer and hepatitis B and C viruses with liver cancer), it is not accurate to say that the majority of cancers are caused by viral infections. The causes of cancer are multifactorial and can include genetic factors, environmental exposures (like tobacco and radiation), lifestyle choices, and infections by multiple types of pathogens (including bacteria and fungi).

Peyton Rous was indeed awarded the Nobel Prize for his discovery of the relationship between viruses and cancer, particularly the Rous sarcoma virus and its ability to cause cancer in chickens, but it does not account for the majority of cancer cases overall.
