Oral sex may raise risks of head, neck cancer

Gorkha Post



LONDON —Oral sex can raise the risk of head and neck cancer by seven times, according to a new study published online in ‘JAMA Oncology’.

The Albert Einstein College of Medicine research shows a strong connection between the human papillomavirus (HPV), which can be spread through oral sex, and head and neck cancer.

The study, which involved nearly 97,000 people in two studies, also shows that the virus can be detected in a mouthwash. The virus can also be prevented with a vaccine.

The virus can raise the risk of getting head and neck cancer by as much as seven times, and maybe by far more, the Independent reported.

Head and neck cancers were long thought to have been caused by smoking and drinking. But a sharp rise in the number of cases led doctors to speculate that there may be another cause, and the new study is the first to show conclusively that HPV-16 precedes the development of those cancers.

The explanation gained particular publicity when actor Michael Douglas said that he believed he had contracted his cancer through oral sex. The new study is proof of the strong connection between those two activities.

NEW YORK — People who are suffering from urinary or respiratory tract infections may face nearly double the risk of heart attacks and strokes than obesity, researchers have warned.

The study — led by a researcher of Indian origin — found that if the frequency of these common infections causing hospitalisation continues for a longer period it may even lead to death.

Patients diagnosed with any one of these common infections were three times more likely to die than those without prior infection after developing heart disease, and almost twice as likely to die if they had a stroke.

“Our figures suggest that those who are admitted to hospital with a respiratory or urinary tract infection are 40 per cent more likely to suffer a subsequent heart attack, and 2.5 times more likely to have a stroke, than patients who have had no such infection, and are considerably less likely to survive from these conditions,” Rahul Potluri, researcher at Britain’s Aston University, said in a statement.

The effects of the common infections were of similar magnitude among the people suffering from diabetes, hypertension, and cholesterol, researchers said.

“It is notable that infection appears to confer as much, if not more, of a risk for future heart disease and stroke as very well established risk factors such as high blood pressure and diabetes,” Potluri added.

Researchers conducted the study over 34,027 patients who had been admitted with a urinary or respiratory tract infection with an age and sex-matched control group without infection.

Factors such as age, gender, ethnicity, obesity and tobacco use, as well as medical conditions including excess cholesterol, high blood pressure, diabetes and kidney disease, heart failure and atrial fibrillation were also taken into account.
