Oral Sex Cause Throat Cancer

The virus is spread during oral sex is now known as the main cause of throat cancer in people under the age of 50, so the scientists warn.
They say, Human Papilloma Virus (HPV) is spread during sex is not safe is suspected as the cause of increased cases of oral cancer is potentially lethal in recent decades.
Doctors have called for boys to be vaccinated against HPV as well as teenage girls to stop the spread of disease.
HPV is known as a major cause of about 70 percent of cervical cancer. Since 2008, girls have been vaccinated against this virus at the age of 12 and 13 years. Besides this virus can also cause warts, verrucas and other cancers.
Cancer of the mouth and oropharynx - the top of the throat - was primarily diagnosed in older men who drink or smoke. But then, this jug disease seen in young men.
Prof Maura Gillison of Ohio State University of Columbus said that sexually transmitted HPV is the cause that is bigger than some oral cancers caused by tobacco.
He said: "We do not know of rigorous scientific evidence whether the vaccine would protect against oral HPV infections that cause cancer. For us in the field, we are optimistic will be able to protect the vaccine - a vaccine that is given each body part so far has proved very effective, about 90 percent effective, to prevent infection '.
'When one of my patients ask if they can vaccinate their children, I said sure. "
Girls aged 12 and 13 years at the school offered the HPV vaccine to protect them against cervical cancer - a disease that kills nearly 1,000 women each year in England. The vaccine is given at the school in three doses over six months.
Doctors are increasingly concerned that a sexually transmitted virus is behind the increase in cancer cases.
In the UK the incidence of throat cancer in the U.S. increased sharply while the incidence of oral cancer associated with HPV have doubled in the last 20 years.
In Sweden in the 1970s about a quarter of thyroid cancer associated with HPV, but in the mid-2000s that figure to 90 per cent said Prof Gillison.
"It is very interesting data in a population that increased tonsular cancer or oropharynx cancer cases that we see in several places around the world might be caused by HPV," she said.
A person infected with HPV 16-related tension, oral cancer has increased 14-fold risk for oropharynx cancer, he said.
He added: "What is most strongly associated with oral HPV infection is the number of sexual partners a person has in their lives, especially the number of individuals on whom they had been performing oral sex."
"The higher the number of partners you have, the more likely that you will have a mouth infection."
Yesterday, the researchers told a conference of the American Association for the Advancement of Science (American Association for the Advancement of Science) in Washington, that teenagers consider oral sex as a 'casual, socially acceptable, with no consequences and low risk to their health than sex " real ". "
Last year a study at Johns Hopkins University found that HPV pose a greater risk of cancer than cigarettes or alcohol.
American study of 300 men showed that those couples who have more than six people is almost nine times higher risk of contracting the disease while those who have experienced previous oral HPV infection is 32 times more likely to develop cancer.
Most HPV infections have no symptoms and people often do not require treatment.Sara Hiom, director of health information Cancer Research UK, said: "Cancer of the mouth and throat have increased dramatically in Britain since the mid-1980s, especially in people in their 40s, 50's and 60's.
'The proportion of total cancer cases associated with infection by HPV appears to have also increased. "
'Although for a while it makes sense to assume that HPV vaccination in girls and boys will protect them against this cancer, but there is no evidence whether the current HPV vaccine is effective for preventing cancer.
'Tests conducted so far been only against cervical cancer or genital warts, so we need new studies to demonstrate the effectiveness of this vaccine-related HPV and head and neck cancer.
'But oral cancers are diagnosed in people aged over 50 years in the UK is still associated with the use of tobacco and alcohol. "
