Lung Cancer Due to Tobacco Use

Introduction

The paper aims to highlight the health issue of lung cancer which is mainly caused by the usage of tobacco. Furthermore, the paper provides the impacts of using tobacco on the health of individual. Lung cancer is one of the most widespread cancers all around the world. It is found to be the leading reason of cancer deaths in the United States (Bjartveit & Tverdal, 2009, pp. 197-205). In view of the researchers, almost 87% of lung cancer incidents are caused by smoking of cigarettes. Cigarette smoking results in 30% of cancer related deaths in most of the developed states.

Smoking provides the body a number of carcinogenic substances that are very harmful to the lungs and can cause uncontrollable growth of cancer cells. Cigarette smoking causes recurrent and chronic airway inflammation, which contribute to the development of cancer. Tobacco smoke leads to abnormalities in the functioning of the cilia lining the respiratory tract, responsible for the removal of dirt particles. In addition, there is a hyper-secretion of mucus, and this can cause chronic cough (Barnoya & Glantz, 2004, pp. 689-95). It can also occur with chronic obstructive pulmonary disease (COPD). Alveoli may be destroyed, resulting in reduced gas exchange surface of the lungs and a reduced supply of oxygen to the tissues.

Thesis Statement

The use of tobacco is the leading cause of lung cancer in today`s world.

Background

Lung cancer was relatively uncommon a century ago, when the use of tobacco was not yet a general habit. Tobacco is the single most preventable reason of deaths in the world. Lung cancer is the most frequent tobacco associated cause of cancer mortality, with a case being created for each 3 million of cigarettes smoked (Alberg et. Al., 2005, pp. 3175-85). Tobacco is the most famous and the most important cause of cancer. Scientifically, there is no doubt that tobacco results in lung cancer. The tobacco industry claims only statistical connections and differences of opinion are to be oriented deception, which is based on the erroneous conclusions drawn from alignments and one-sided presentation of information (Shapiro, 2000, pp. 333-37).

The relationship between lung cancer and cigarette smoking, it is much easier to understand and much better known to most people than the relationship between exposure to carcinogens in the diet, and other types of cancer. Cigarette smoking is a major cause of lung cancer; smoking causes not only the effect of the formation of cancerous cells, but also to their regular diet (Karl, 2005). In other words, those who have smoked cigarettes from the beginning of the adult age, are exposed to more risk of developing cancer, due to the long-term harmful effects of carcinogens, which are generated during smoking. Unfortunately, statistics confirm these observations.

The smoker's risk of developing lung cancer is ten times greater than non-smokers as compared to their own. In view of the researchers, nine out of ten lung cancers found in smokers, and smoking cessation reduces this increased risk of lung cancer (Shapiro, 2000, pp. ...
