They link to HPV+ cancer head and neck provided for a different treatment plan than from head and neck cancer from risk factors, ie smoking and drinking mainly. It was found that HPV+ does not typically spread below the neck, and responds very well to radiation therapy. Outcomes are favourable. All I can say is thank God for the vaccine programes in schools to vaccinate for HPV at a young age so that the next generations can be spared from cancers caused by HPV. Not only head and neck, but cervical and other cancers as well that are linked to HPV.
