Lung cancer essay conclusion

Evidence on the barriers to diagnosis and treatment in country contexts — and the lessons learned in overcoming them — would be especially welcome contact at http: Therefore, by the time the public reads this report, there may be additional published studies or data.

The evidence is sufficient to infer a causal relationship between secondhand smoke exposure and lung cancer among lifetime nonsmokers. An extensive body of literature on the classification of exposures to secondhand smoke is reviewed in this and other chapters, as well as in some publications on the consequences of misclassification Wu WHO also welcomes requests from countries for information relevant to their specific needs.

The cure for lung cancer is not finalized, and remains an epidemic. This chapter considers these methodologic issues in anticipation of more specific treatment in the following chapters. However, it is rapidly diluted as it travels away from the burning cigarette.

The evidence is inadequate to infer the presence or absence of a causal relationship between chronic secondhand smoke exposure and an accelerated decline in lung function.

Pooled relative risks from meta-analyses indicate a 25 to 30 percent increase in the risk of coronary heart disease from exposure to secondhand smoke. Initial chapters were written by 22 experts who were selected because of their knowledge of a particular topic.

These mutations in the genetic material of the lung cells cause the instructions for those cells to go askew. Chapter 10 Control of Secondhand Smoke Exposure considers measures used to control exposure to secondhand smoke in public places, including legislation, education, and approaches based on building designs and operations.

Sudden Infant Death Syndrome 4. Consequently, exposure is only one determinant of variation in cotinine levels among persons; there also are individual variations in metabolism and excretion rates. This type of misclassification lessens the contrast between exposure groups, because some truly exposed persons are placed in the unexposed group and some truly unexposed persons are placed in the exposed group.

Separating smokers from nonsmokers, cleaning the air, and ventilating buildings cannot eliminate exposures of nonsmokers to secondhand smoke.

Lung Cancer Research Paper

The evidence is sufficient to infer a causal relationship between exposure to secondhand smoke and sudden infant death syndrome. Because of its dynamic nature, a specific quantitative definition of secondhand smoke cannot be offered.

A microenvironment is a definable location that has a constant concentration of the contaminant of interest, such as secondhand smoke, during the time that a person is there. Current heating, ventilating, and air conditioning systems alone cannot control exposure to secondhand smoke. Emerson and colleagues evaluated the repeatability of information from parents of children with asthma.

Workplace smoking restrictions lead to less smoking among covered workers. The evidence is inadequate to infer the presence or absence of a causal relationship between prenatal and postnatal exposure to secondhand smoke and other childhood cancer types. The extent of the data had increased substantially since Because of its dynamic nature, a specific quantitative definition of secondhand smoke cannot be offered.

Also, genetics and past lung illnesses can lead to the development of this type of cancer. The evidence is sufficient to infer a causal relationship between exposure to secondhand smoke after birth and a lower level of lung function during childhood.

The consequences for epidemiologic studies of misclassification in general are well established Rothman and Greenland The evidence is inadequate to infer the presence or absence of a causal relationship between exposure to secondhand smoke and cognitive functioning among children.

The challenge of accurately classifying secondhand smoke exposures confronts all studies of such exposures, and consequently the literature on approaches to and limitations of exposure classification is substantial.

The evidence is inadequate to infer the presence or absence of a causal relationship between secondhand smoke exposure and a risk of nasopharyngeal carcinoma among nonsmokers.

For example, in the multicenter study of secondhand smoke exposure and lung cancer carried out in the United States, Fontham and colleagues assessed exposures during childhood, in workplaces, and at home during adulthood.

Its main goal is to cure cancer patients or prolong their life considerably, ensuring a good quality of life.

Cause of Lung Cancer

The evidence is sufficient to infer that exposure to secondhand smoke causes atherosclerosis in animal models. The evidence is sufficient to infer a causal relationship between maternal smoking during pregnancy and persistent adverse effects on lung function across childhood.

They found a high reliability for parent-reported tobacco use and for the number of cigarettes to which the child was exposed in the home during the past week. A Research Study On Lung Cancer - Action plan Introduction Lung cancer is the uncontrolled growth of abnormal cells that begin in one or both of the lungs; usually found in the cells that line the air passage.

Tobacco use is the most important risk factor for cancer causing over 20% of global cancer deaths and about 70% of global lung cancer deaths. It is expected that annual cancer cases will rise from 14 million in to 22 within the next two decades. Conclusion for essay Ⅴ.

lung cancer Essay - Lung cancer is the most common cancer-related cause of death among men and women. Lung cancer can be undetected for many years causing it to become more dangerous and possibly fatal.

There is not cure for lung cancer or any cancer, but if detected in an early stage the lung cancer can be detected, treated, and hopefully. A plan for the diagnosis and treatment of cancer is a key component of any overall cancer control plan.

Its main goal is to cure cancer patients or prolong their life considerably, ensuring a good quality of life. What Lung Cancer is, How Cells Become Cancerous, and What Carcinogens Are - In this seminar (essay) we will be discussing cancer, specifically lung cancer, what it is, how cells become cancerous, and what carcinogens are.

Cause of Lung Cancer

While lung cancer remains a very challenging cancer to treat, new treatments that capitalize on advances in our understanding of cancer biology are providing both patients and physicians with a reason for cautious optimism.
