People who use tobacco
are more susceptible to oral human papillomavirus type 16 (HPV-16), which is a
sexually transmitted infection, revealed a new US research.
Researchers state that oral
is one of the main reasons for the increase in incidence of
oropharyngeal squamous cell cancers
The study observed a
connection between self-reported number of cigarettes
currently smoked per
day and oral HPV prevalence.
Carole Fakhry from the Johns Hopkins
University School of Medicine, Baltimore, and along with her research team
examined connections between objective
reflective of all
exposures (environmental, smoking, and use of smokeless tobacco) and oral
The scientists used
results of the National Health and Nutrition Examination Survey (NHANES), a
probability sample of the U.S. population. Mobile examination center
participants aged between 14 and 69 years were eligible for oral HPV DNA
The analysis included
6,887 NHANES participants, of them 28.6% (2,012 people) were current tobacco
users and 1% (63) had oral HPV-16 detected.
The results showed
that current tobacco users were more likely than nonusers to be male, younger,
uneducated, and to have a higher number of lifetime oral sexual
Researchers conclude that self-reported and
biological measures of tobacco exposure as well as oral sexual behavior were
significantly linked with prevalent oral HPV-16 infection. Oral human
type 16 prevalence was greater in present tobacco
users (2.0 percent) compared with never or former tobacco users (0.6%).
Effect of Smoking Cigarettes
Tobacco contains more than 7,000 chemicals
and about 70 of them can cause cancer. Smoking
cigarettes is one of the main risk factors for lung cancer. It is also known to
cause cancer in the trachea, bronchus
, esophagus, oral
, lip, nasopharynx, nasal cavity, larynx, stomach
, kidney, liver
uterine cervix, colon and rectum
* Do Light Cigarettes Cause Cancer?
Cigarettes labeled as 'lights,' and 'milds,' are considered to have a 'lighter,' less
pronounced flavor than regular cigarettes. However, there is no such thing as a
safe cigarette. People who smoke any kind of cigarette are at an increased risk
for tobacco-related diseases.
* Do Menthol Cigarettes Cause Cancer?
A menthol cigarette is a cigarette flavored with
the compound menthol. Many people think menthol cigarettes are less harmful,
but there is no proof that these cigarettes are safer than regular cigarettes.
Like other cigarettes, menthol cigarettes harm nearly every organ in the human
body and cause many diseases, including cancer
