An analysis of environmental tobacco smoke and lung cancer

an analysis of environmental tobacco smoke and lung cancer Between exposure to environmental tobacco smoke and the risk of lung cancer on the basis of a meta-analysis of 13 studies, 10 of which were retrospective and the remaining 3 prospective in nature, the council concluded that non-smokers who are exposed to environmental tobacco smoke are at greater risk of acquiring lung cancer than non-smokers not so exposed.

Smoking and lung cancer at the same time the tobacco industry's own research began to find carcinogens in smoke and began to confirm the relationship between smoking and cancer. The environmental protection agency noted in its report from 1992 that there was an increased risk for lung cancer from ets and estimated that it accounts for approximately 3000 lung cancer deaths in the us. Given the limitations of the underlying data in this and the other studies of environmental tobacco smoke and the small size of the risk, it seems premature to conclude that environmental tobacco smoke causes death from coronary heart disease and lung cancer. Methods: we performed a meta-analysis in 2003 of data from 22 studies from multiple locations worldwide of workplace environmental tobacco smoke exposure and lung cancer risk estimates of relative risk from these studies were analyzed by fitting the data to fixed and mixed effects models.

Tobacco smoking is by far the leading cause of lung cancer about 80% of lung cancer deaths are caused by smoking, and many others are caused by exposure to secondhand smoke about 80% of lung cancer deaths are caused by smoking, and many others are caused by exposure to secondhand smoke. A recent meta-analysis [1] of tobacco smoke exposure and lung cancer was carried out by statisticians in the british consulting firm pn lee statistics and computing ltd they studied more than a hundred of publications and the potential causal relationship between passive smoking and lung cancer. Environmental risk factors for lung cancer at about the time that the association between tobacco smoking and lung cancer was confirmed, evidence also was obtained regarding the causal relationship between asbestos and lung cancer.

Secondhand tobacco smoke is the combination of the smoke given off by a burning tobacco product and the smoke exhaled by a smoker it is also called environmental tobacco smoke, involuntary smoke, and passive smoke. A meta-analysis of the relationship between environmental tobacco smoke and lung cancer risk of nonsmoker in china sheng l(1), tu jw, tian jh, chen hj, pan cl, zhou rz author information: (1)department of respiratory medicine, jinhua municipal central hospital, jinhua, zhejiang, china. Passive smoking is the inhalation of smoke, called second-hand smoke (shs), or environmental tobacco smoke (ets), by persons other than the intended active smoker it occurs when tobacco smoke permeates any environment, causing its inhalation by people within that environment.

As smoking rates declined, we continue to see more patients diagnosed with lung cancer who do not have a prior smoking history, said reckamp, who wasn't involved in either study. Core tip: we present an up-to-date meta-analysis of the evidence relating non-smoker lung cancer to environmental tobacco smoke (ets) exposure we demonstrate a clear risk increase for spousal, at-home, workplace and total exposure, but not childhood exposure. In this study, we evaluated the secondhand smoke-lung cancer relationship by histological type based on pooled data from 18 case-control studies in the international lung cancer consortium (ilcco), including 2,504 cases and 7,276 control who were never smokers and 10,184 cases and 7,176 controls who were ever smokers. This comparison would help determine whether lung cancer development in smokers versus non-smokers exposed to shs is merely a question of smoking doseā€”ie, to verify whether the different risks of lung cancer development is only dependent on smoking dose since shs is still only cigarette smoke.

A meta-analysis was carried out to calculate a pooled estimate of relative risk of lung cancer following exposure to environmental tobacco smoke (ets) and to determine whether there was any heterogeneity in the pooled estimates according to selected characteristics of the studies. Secondhand smoke (shs) is also called environmental tobacco smoke (ets) it's a mixture of 2 forms of smoke that come from burning tobacco: mainstream smoke: the smoke exhaled by a smoker sidestream smoke: smoke from the lighted end of a cigarette, pipe, or cigar, or tobacco burning in a hookah. Asbestos, for example, enhances the carcinogenicity of tobacco smoke, so the rate of lung cancer was especially high among people who smoked and also were exposed to asbestos in their workplaces.

More than 50% of women worldwide are exposed to environmental tobacco smoke (ets) the impact of ets on lung cancer remains unclear cohort studies since the late 1990s have provided new evidence of female lung cancer risk due to ets the objective of this meta-analysis and systematic review was to. Environmental tobacco smoke (ets) is considered a possible cause of lung cancer in never-smokers, as confirmed by many studies a meta-analysis of 55 studies of never-smoking wives, living with smokers, showed a significant increase of lung cancer [ 7 . Environmental tobacco smoke (ets) are relatively important methods an age-matched case-control study was designed to investigate the effects of cumulative environmental exposure to tobacco smoke during childhood and adult.

  • We performed a meta-analysis in 2003 of data from 22 studies from multiple locations worldwide of workplace environmental tobacco smoke exposure and lung cancer risk estimates of relative risk from these studies were analyzed by fitting the data to fixed and mixed effects models.
  • In 1993, the epa published a report claiming that secondhand smoke (shs -- also sometimes known as environmental tobacco smoke or ets) causes three thousand deaths from lung cancer every year.

Place environmental tobacco smoke exposure and lung cancer methods we performed a meta-analysis in 2003 of data from 22 studies from. Chapter 3 smoking prevalence and lung cancer death rates introduction the use of cigarettes, in contrast to other tobacco prod- ucts, is a behavior that has developed relatively recently. Second-hand smoke, also known as environmental tobacco smoke or passive smoking, exposes people to cancer-causing chemicals [3] people who have never smoked have their risk of lung cancer increased by around a quarter if they have a spouse who smokes [1,5. One good example is the challenge to the united states environmental protection agency's risk assessment of passive smoking, also known as environmental tobacco smoke (ets) in 1992, the environmental protection agency (epa) published a risk assessment of lung cancer (and other) risks from ets.
