Oral sex increases neck cancers

It was news that the global incidence of cervical cancer is declining, largely because fewer people smoke (the snuff and alcohol are the major traditional risk factors), but now there is a rise in the incidence of some cancers of the neck among Americans for oral sex, according to the Faculty of Medicine and Public Health at the University of Wisconsin in Madison. The alarming thing is that it is targeting older people, but are cases in middle-aged and younger. The reason some experts say has to do with the increased popularity of oral sex in the last decades.

Oral sex and cancer human papilloma virus (HPV) is an important cause of these cancers, and that HPV can be transmitted through oral sex. A 2007 study found that young people with head and neck cancers who tested positive for oral HPV infection were more likely to have multiple oral and vaginal sex partners over their lifetime. It was the conclusion that having six or more oral sex partners in life increased the risk 3.4 times higher oropharyngeal cancer, ie cancer of the base of the tongue in the back of the throat or tonsils. Having 26 or more vaginal sex partners tripled the risk. Moreover, as cancers of the tonsils and base of the tongue have increased every year since 1973, suggests that the widespread practice of oral sex among teens may be a contributing factor in this increase. Another Swedish study in 2010 suggested that the increase in oropharyngeal squamous cell cancer in several countries is a slow epidemic caused by HPV infection. According to experts explain, HPV tends to remain in first place entering the body , so it has been affected the mouth and throat.

More oral sex now in 1992 showed that about three quarters of men aged 20 to 39 years and about 70 percent of women age 18 to 59 made and received oral sex in 2002, nearly 90 percent of men and 88 percent of women 25 to 44 reported having oral sex with a partner of the opposite sex, according to the Centers for Disease Control and Disease Prevention (CDC). UU. HPV and cancer of the only good news is that cervical cancers associated with HPV are more treatable than those due to smoking or drinking, although the former tend to be diagnosed at a later stage. You can use less intensive radiation and about 85 percent of nonsmokers and positive HPV survive suffer. After this is important there is a vaccine redordar relatively new to prevent HPV infection. It will not help those already infected, but it might help those who are not yet infected.
