Caught in the act: Papillomaviruses promote non-melanoma skin cancer

UV radiation has been known for a long time to be a risk factor for the development of skin cancer. Simultaneous infection with human papillomaviruses (HPV) has also been suspected to promote skin cancer, particularly in organ transplant recipients. Scientists have now been able to show for the first time in a natural system that papillomaviruses associated with UV light promote the development of non-melanoma skin cancer.
