A new study suggests that smoking that the risk of head and neck cancer plus oral sex may be a fatal combination for men.
The main factor is the transmission of oral strains of cancer related human papillomavirus (HPV) that can undergo oral sex.
Dr. Otis Brawley,who is CTO of the American Cancer Society, says:
When reviewing the new study, it probably said that the incidence of intraoral HPV infection in white men in their 50s and 60s is rising, due to increased oral intrinsic acceptance.
Certain groups are at high risk. One recent study found that 11 million American men are infected with oral HPV. This means that 1 out of 9 men in the United States between 18 and 69 years are infected.
Researchers found that male and female with one or no intraoral sexual partners had the lowest prevalence of oral HPV causing cancer.
However, the rate of HPV infection increased in smokers, and men and women had two or more oral sex partners, but the rates were still low.
The risk of smokers and men with 2-4 oral sex partners dramatically increased to 7%. Mr. Dusa's team found that the risk of men who are not smoking but who have five or more oral sex partners rose to nearly 7.5%.
Also, the greatest risk (about 15%) was seen among male smokers with more than 5 oral sex partners.
Patti Gravitt is a professor in the department of global health at George Washington University in Washington, D.C. She said that the relevance between oral HPV and smoking is unclear. She says "We also see a connection between smoking and cervical cancer, so it's likely that smoking and HPV interact in some way to increase the risk of cancer."
While various religions forbid adultery, in fact, both males and females usually had multiple partners in their lifetime.
There is also a research result that it was the spread of venereal disease, the biggest reason why we moved from polygamy to monogamy. In addition to classical venereal diseases such as syphilis and gonorrhea, deaths caused by cancer also seem to have caused many causes. For people over 1000 years old, it is not difficult to imagine that "cancer" was a death of unknown causes. People just died without reason. Empirically, it is found that people are healthy and live longer when they are monogamy. For this reason, it is said that it shifted to monogamy.
