"Current smoking is a very important promoter of the disease," said Daling, also a professor of epidemiology at the University of Washington School of Public Health and Community Medicine."There's a fourfold increase in risk if you're a current smoker, regardless of whether you're male or female." "Even in controlling for other risk factors, like the number of sexual partners, anal intercourse, and HPV status, smoking was a strong risk factor for squamous-cell anal cancer," Daling said, referring to the most common type of anal cancer, which accounts for about half of all cases.The survey also reported that black men, the group with the highest anal-cancer incidence in the current study, were more likely than white men to report having had intercourse with another male in the last year."It could be that sexual practices have changed, but it also could be that people are just more likely to discuss their sexual behavior these days," Daling said.Thumbnails are automatically generated from the pictures.Please contact us if you have found inappropriate content.The five-year survival rate for black men with early stage disease was 62 percent as compared to 79 percent for white men with localized cancer.
Since the blood test can only detect HPV antibodies in a subset of those who are exposed to the virus, the overall HPV exposure among the control group was probably much higher, Daling cautions.Overall, regardless of the patient's sexual orientation or gender, the researchers found that 88 percent of the tumors were positive for HPV DNA.Of these, 73 percent tested positive for a strain called HPV-16, and 7 percent contained a strain called HPV-18.Disclaimer: Go HD is a fully automatic adult site with twink galleries.We do not own, produce, host or sell the content displayed on this website.
