Oral sex more than tobacco as a cause of cancer of garga

(In this way, the sexual transmission of human papillomavirus (HPV)) than tobacco as the leading cause of these diseases in that country.


This was stated by Maura Gillison, researcher at the University of Ohio (United States), in the course of the meeting of the American Association of scientific advances (AAAS, in English) which these days is held in Washington. Its conclusions are consistent with previous studies, which concludes that the citizens who performed oral sex with more than six individuals have eight times more likely to develop this disease than the less promiscuous.


The researchers found a 225% increase in cases of oral cancer resulting from infection by HPV between 1974 and 2007, especially among white males. As he published the newspaper El Mundo, the center of Control and prevention (CDC) estimates that over the past two decades has doubled the number of infected by HPV in the United States and predicted that half the American population sexually active contract the virus throughout his life.


In most cases, infection is without symptoms and the human body is able to control it without further problem. However, as a percentage of the cases, infection persists in a latent manner and can cause premalignas injuries, first step towards cancer (as in the case of tumors of the cervix in women).


There are two vaccines approved by health authorities, both in the U.S. and Europe: Gadasil and Cervarix. They were given the go-ahead in 2006 to combat the HPV in cases of cancer of the uterus and genital warts, but still not demonstrated its effectiveness in oral cancer infections.


Despite this, Gillison calls for vaccinating young men as that for now the girls tend to be covered more frequently than men. “They have more risk of contracting cancer of the mouth or throat due to unsafe sex.” According to the National Institute of cancer in the United States, there are 150 different types of HPV and 40 of them can be sexually transmitted.


John Curtis is Professor of Gynecologic Oncology of the University of New York and stressed that “oral cancer is usually diagnosed too late and that tends to be a stumbling block to recovery”.


“It is true that there is much to go and that still found no evidence that vaccination is able to give protection against papillomavirus in oral infections.” “Even so I am optimistic and I think that they should be more accessible to the people (its price is around 400 euros), will be so that every time there is more protected persons”. Hygiene and annual visits to the dentist are still, according to the Professor, an effective way to control possible infections.


Curtis States that the recent results that show the rise in cases of oral cancer by HPV on tobacco, are worrying. “The conclusions represent a message clear: oral sex has the same risks that either vaginal or anal, therefore need to educate young people so it can be prevented”.


In the Argentina, in early February, President Cristina Kirchner announced the inclusion of HPV vaccine in the mandatory vaccination schedule. “The vaccine is now on sale, but it must be a certain level purchasing and information to access it,” said the President during the announcement, and stressed that “now it will be part of the immunization schedule and will allow thousands of women lose their life for this cause”.
