Lung cancer was a less known condition till after the WWI when a sudden increase in number of cases affected by tumors of the lower respiratory tract was noticed. Prior to the WWI, the tobacco industry has increased its production manifold which was directly related with the increase in number of patients with lung cancer. Even though the tobacco industry denied having anything to do with this increase, it was

diseases i.e. lung cancer, childhood leukemia, obesity and Alzheimer's disease. In each explanation, I have included a definition of the disease, risk factors, treatments, prognosis, and prevention. Later, I have provided short literature reviews of four articles. Lung Cancer Lungs are those organs in the body that help the human beings to breathe i.e. inhale and exhale oxygen. Their primary function is to provide oxygen to every cell in the body.

Lung Cancer Cancer is a complex genetic disease in which a series of processes give rise to the final processing of the normal cell to cell tumor. In case of a tumor cell, the fundamental characteristic of the cell is lost which performs the usual function of normal cells of a particular organ. Tumor cells also deteriorate rapidly and without limit, having lost one of the features that normal cells have,

Apical growth may lead to shoulder pain radiating in an ulnar distribution. "The superior vena cava can become obstructed and involvement of the heart and pericardium can occur. Lymphatic obstruction and spread can lead to dyspnea, hypoxia, and pleural effusions. Distant metastatic disease can affect most organs. Neurologic symptoms may suggest brain metastases or spinal cord compression, and pain could indicate bone metastases" (Mazzone 2004). Treatment Surgery is the usual recourse

Cancer nurses with sufficient knowledge of the biological basis of these therapies would be better equipped to deal with the practical clinical implications and provide better symptoms management. The technical understanding of the nurses is also crucial in educating and in enabling the patients to take care of themselves. Further, it also goes without saying that nurses, as the primary caregivers are responsible for the emotional well being of

Smoking and Lung Cancer Cohort, cross sectional, and case-control studies are together known as observational studies. These studies are frequently the only feasible manner of analyzing certain problems (Mann, 2003). In this particular case, the observational studies shall concentrate on smoking together with lung cancer. COHORT STUDY This is the most appropriate manner of establishing the condition's prevalence and natural history. Conducting Study A group of individuals that do not have the desired outcome
