The report above also indicates that you are unsure about why Whites are affected by HPV cancer, both in number and increase, when you read this report on page 26 shows of course that any increase is not found in other groups than just white, is someone completely seriously claim that only whites have or have had an increase in oral sex? http://www.cancer.org/acs/groups/content/@epidemiologysurveilance/documents/document/acspc-031941.pdf
No increase in the percentage of groups african american, asian or pacific, American Indian, Alaska Native or Hispanic Latino, these groups have not oral sex?




"However, existing data do not provide a clear explanation for the observed differences by race. Additional research is needed to clarify the routes of oral HPV transmission and to develop appropriate, targeted prevention strategies."
