Essays on Lung Cancer

Freudenheim, Van den Brandt, Colditz, Goldbohm, Harnack et al. (2005) hypothesized that alcohol consumption increases the risk of lung cancer. Smoking is known widely as the primary cause of cancer of the lungs but a lot remains unknown on the etiology of lung cancer. The study involved a pooled analysis of standardized covariate and exposure data from 7 different prospective studies comprising 3137 lung cancer cases and 399,767 participants. In terms of collection of information, the authors collected information by pooling cohorts, which were arrived at using the criteria of incident lung cancer cases, dietary assessment, a validation

Lung cancer (also called – carcinoma of lungs) is a type of malignant tumor. It emerges from cells paving lungs and bronchi. Usually it takes years for this type of cancer to develop. But if a person gets this type of disease most likely other organs will be affected as well. Lung cancer is a really dangerous for a human, as it is hard to diagnose it and it might be too late to treat it. This disease contributes to the major part of deaths throughout the developed countries. Annually there are about 1 million cases of lung cancer around

Introduction

Lung cancer has remained the leading cause of cancer deaths in both men and women in United States. According to International Agency for Research on Cancer (IARC), approximately 1.35 million new cases of lung cancer are diagnosed across the world each year. There are a wide number of risk factors associated with lung cancer. These are smoking, exposure to asbestos, silica exposure, and diesel exhaust. The most common cause is the exposure to tobacco smoke through either active or passive smoking. Males are at a higher risk of lung cancer than females, a ratio of 7.8 to 5.8 respectively.

Smoking cigarette may although appear as an attractive practice trying to captivate the interest of a lot of people particularly the youth, but is the practice actually that attractive to be allowed to play with the health of a person? Does smoking cigarette have no ill effects on the health of an individual? Surely is does have, rather a lot of them! The most adverse effect that a cigarette can have on an individual’s health is lung cancer, which if not treated within the right time period even possesses the power to become a fatal disease. Lung cancer

Immunity Regulation in Natural Killer (NK) Cells

Introduction
Research indicates that lung cancer forms a 24.5% of all the malignant tumors that can happen in the body of a human being. There have been efforts to find the treatment that would eliminate or reduce the spread of cancerous cells to no avail. The procedures that remain as viable options could include surgical resection, which only works to prolong the life of a victim of lung cancer. The natural killer cells can be an option in fighting the spread of cancerous cells. They are nonspecific killer cells, which denotes to their being able to fight all kinds

- Apparently, pollution has been a topic that requires lots of attention during the past and predominantly the present time. This topic had been a phenomenon, beginning at the time when the relationship between human beings and the environment became apparent. Pollution became rampant the time when human beings begun destroying the environment with no regards to the aftermath effects like pollution. In this way, the pollution problem developed and became a huge issue of concern. With developments and innovations, people began depending on machines a fact that made the issue of pollution more sophisticated.
- Owing the gradual

Biology

Introduction
Lung cancer is a leading cause of death worldwide. Natural killer cells play a critical role in immunotherapy for cancer patients. The natural killer or NK cells play a crucial role in cancer patients and developing an understanding of the mechanisms through which their activity is inhibited or enhanced in the case of cancer patients, shall contribute a great deal in finding the most suitable and effective treatment of cancer patients and also enhance their life. The present research paper is restricted to the study of cell mechanisms involving NK cells and their inhibitor and activators in the

Lung Cancer in Canada

Lung Cancer in Canada

Problem Identification

Lung cancer is the most commonly diagnosed cancer in Canada, not counting non-melanoma skin cancers. Lung cancer is also the most common cause of death in Canada for both men and women. Particularly high rates are seen in the elderly, especially those over the age of 75. While Canada’s system of socialized medicine is applauded as a model for other countries struggling to establish government subsidized healthcare, there are also problems in Canada’s system. In a socialized medicine system, cost is always a factor, and there are rarely as many services as needed

As a nurse, understanding health education helps one to solve many medical challenges facing patients. Unless people understand key concepts about their health, it is, however, the role of nurses and other stakeholders in the health care sector to ensure that people understand these concepts.

Part 1

In my nursing experience, I had the opportunity to interact with a patient who was suffering from lung cancer. The patient who was a chain smoker believed that death is inevitable, and his fate was already predetermined long before he started suffering from lung cancer. He did not believe that his smoking habit has

Lung cancer is a deadly disease that jeopardizes health of people globally. Diagnosis of this disease has made it difficult to be prevented or treated since no single test has been found to diagnose lung cancer accurately. Hence, series of tests have been implemented to test for this disease. The diagnosis of the disease has enabled doctors to come up with some specific and accurate preventive measures that have been put in place to reduce the incidences of this disease. The section of this paper will therefore discuss laboratory measures and diagnosis of lung cancer, useful tumors of cancer

The epidermal growth factor belongs to the HER family receptor tyrosine kinases and it regulates cell differentiation and cell growth and interlinked with several human cancers. The signal transductions in the cells are controlled by EGFR. It is one of the oncogene which is involved in producing cancers via over expression of the ligands and the continuous activation and amplification of EGFR. The activity of the EGFR can be reduced by monoclonal antibodies against them. The activation of the EGFR is activated by binding of the transforming growth factor. The EGFR binds to receptor of HER family in order

The lung cancer is of primary concern among western population in the western world by virtue of exaggerated rate of smoker compared to non smokers. The pathology of lung cancer comprises of genomic instability resulting in abnormalities over a long span. The variations occur at gene level via process called as gene silencing mediated methylation; amplification of DNA, sequence changes in DNA along with looses and gains of whole chromosome. The genetic alterations observed in cell lung cancer contain a loss of regions which are in turn part of the genome especially chromosomes 9p and 3p and it is
