NEW YORK (Reuters Health) – Smoking and oral sex can be a deadly cough that increases a man’s risk of head and neck cancer, according to a new study.
The main factor is the transmission of oral strains of human papilloma virus (HPV), which can be transmitted through oral sex.
In fact, men who smoke and have five or more partners with whom they have oral sex (in this study, which usually means swelling of the flesh) have the highest risk of a type of head and neck cancer known as oral pharynx.
D. Otis Brawley is a senior physician of the American Cancer Society. “The incidence of oral HPV appears to be higher among white men in the 1950s and 1960s, possibly because of the greater acceptance of oral sex,” he said.
However, the risk of head and neck cancer associated with HPV remains very high for most people, said research team leader Amber Desosa. An associate professor of epidemiology at the Bloomberg Johns Hopkins School of Public Health in Baltimore.
“The risk is much lower among women and non-smokers, and people with few oral partners,” he said.
Trialix Desouza said the new findings “should reassure people that the spread of human papilloma virus (HPV), which causes cancer, is low among most groups.”
But some groups have higher risks. A recent study found that 11 million men in the US UU They are infected with HPV orally. That means one in nine American men aged 18 to 69.
Brawley said the increase was due in part to the sexual revolution in the 1960s and 1970s. “The increase in oral sex has led to an increase in the number of people infected with HPV [by mouth],” he said.
For the new study, D’Souza’s team reviewed data on more than 13,000 people between the ages of 20 and 69 who participated in a large federal government survey and tested human papillomavirus infection.
This survey is a nationally representative group, so it is likely that the vast majority of male participants who said they were active partners in oral sex were heterosexuals who shared cunnilingus.
To predict the risk of cancer from an HPV infection, the researchers used the number of cases of throat cancer and deaths from cancer registries in the United States.
The researchers found that men and women who have one or no partner in oral sex have the lowest rate of HPV spread that causes cancer.
The incidence of HPV in smokers increased, but the rate also increased when men and women had oral sex partners, although rates were still low.
The risk increased significantly, up to 7 percent, among men who smoked and had two to four couples in oral sex. The risk increased to around 7.5 percent among men who did not smoke but had five or more partners in oral sex.
Testo Drive 365 The results showed that the highest risk (around 15 percent) was observed among men who smoked and who also had five or more oral sex partners.
D’Souza detects more than 100 types of HPV, but only a few types of cancer, including cervical cancer, are detected by D’Souza.
Brawley noted that most people who use HPV get rid of it naturally within nine months. “But there is a group of people who become infected and maintain the infection for 20 or 30 years, those people who end up with head, neck or cervical cancer,” he said.
Each year in the United States, about 16,500 cases of throat cancer are diagnosed. Among them, 11,500 (70 percent) are associated with HPV infection, said D’Souza
He said that d. Susa said that testing for HPV infection by mouth may not be the solution because cancer is extremely rare. “Current tests can determine who has oral HPV but does not predict cancer risk in the future,” he said.
Brawley suggested that prevention is available: the HPV vaccine. He said that at an early age he protects against cervical cancer and anal cancer and probably protects head and neck cancer. Canada
Brawley said the hope is that as time passes with more children vaccinated, the types of cancer caused by HPV will be greatly reduced.
Patty Graft is a professor in the Department of World Health at George Washington University in Washington, D.C. She said the link between the oral oral papilloma virus and smoking was unclear.
“We also see a relationship between smoking and cervical cancer, so smoking and HPV probably interact in some way to increase the risk of cancer,” Graft said.
