It helped both my husband and me to know that his cancer was caused by HPV. Plus, he was treated at Hopkins where much of the research on the role of HPV is being studied and we liked feeling that we were contributing to a greater understanding of oral cancer (something positive out of a bad situation). But, I think it's a very individual decision as knowing his was HPV+ has made us wonder how that could be given our very long-term, monogamous relationship (e.g., how long does this virus stay in the body or are there other means of transmission?), what about risks to me?, has the virus really gone away?, etc. So, you answer one question but are left with others.
