In fact, in a study involving 6887 participants, of which slightly more than 2000 smokers (predominantly young men having oral sex with multiple partners), links between the risk of developing oral cancer (a category that includes the cancers of the mouth and throat), smoking and oral sex have been clearly established.
According to the researchers, oral sex and smoking increase the incidence of oral infections. A papillomavirus, known among scientists as the HPV16 usually rejected by the body without causing any damage, then infiltrate in the latter to increase the risk of oral cancer. Earlier studies have also established a link between oral sex and disease.Surprising results
In reaching this conclusion, researchers from Johns Hopkins University (Baltimore) used mouth rinse method to detect the virus. Then, they analyzed the blood and urine of participants to identify the presence of cotinine and NNAL two elements present in tobacco users (smoked or chewed).
Results: The presence of cotinine in the blood, the equivalent of three cigarettes a day increases by 31%, no less, the risk of HPV infection. Worse: for every increase of NNAL levels in the urine (four cigarettes smoked daily), the probability of contracting an infection linked to HPV16 virus made a surprising jump of 68%. Bleak, especially as the number of cancers in this body area surged by 225% in 20 years, the United States only.What papillomavirus HPV16?
The HPV16 papillomavirus is responsible for skin lesions or genital mucosa. It is particularly involved in the warts, but also in some sexually transmitted infections, which can sometimes generate precancerous lesions of the cervix in women. It mainly affects genital mucosa and the risk of cancerous development is high, according to the description provided by Santemedecine.net **.
Now it papillomavirus is also sent to the oral mucosa during fellatio or cunnilingus. It would even be liable to 80% of cancers that affect the mouth and / or throat.
Despite the link between HPV and those dreaded cancers, researchers do not know the reasons that tie directly related cancers this virus and smoking. However, they believe that the body of a smoker would have more difficulty in getting rid of this pathogen.
Although researchers have established a direct link between increased risk of developing oral cancer, smoking and oral sex, more research is needed to identify the combination of factors that causes among some, the appearance oral cancer while others are exempt.Oral cancers in Canada
In Canada, oral cancer ranks thirteenth on 23 cancers that attack the human body. An estimated 4160 people, more men than women are diagnosed with oral cancer in 2013. The survival rate after five years is 63% compared to 75% for cancer victims the cervix. The main risk factors are age - that cancer develops in people over 40 years-smoking and alcohol, and a diet low in fruits and vegetables. Furthermore, the sun is also pointed, especially when oral lips are affected.
The signs and symptoms of oral cancer include:
Mouth sores that take more than two weeks to heal.
Dark red or white patches in the mouth.
Nodules on the lips, tongue or neck.
Bleeding in the mouth.
Itchy throat and difficulty swallowing.
White or red patches in the mouth and on the tongue.
Difficulty moving the jaw or tongue.
With respect to cancer of the throat (larynx and esophagus), Health Canada estimates that 2,405 men and 640 women were reached in 2013. It seems that alcohol consumption, higher among men, to be partly responsible this gender disparity.
Despite fears related to various types of cancer, couples need not abandon oral / genital sex. A healthy mouth, a healthy diet, quitting smoking and regular visits to the dentist reduce the risk of getting oral cancer. There goes your health ... and your enjoyment.
