According to the National Cancer Institute

According to the National Cancer Institute, lung cancer is the second most common cancer and primary cause of cancer-related death in both men and women in the United States. The overall death rate for lung and bronchus cancers rose steadily through the 1980s, peaked in the early 1990s, and has been slowly declining since 2001. Trends in lung cancer incidence and death rates have closely mirrored historical patterns of smoking prevalence, after accounting for a gap period. Because the prevalence of smoking peaked later in women than in men, lung cancer incidence and death rates began declining later for women than men. The incidence rate has been declining since the mid-1980s in men but only since the mid-2000s in women; the mortality rate began declining in 1991 in men and but not until 2003 in women. Incidence and mortality rates are highest among African American men, followed by white men.
Although smoking is the main cause of lung cancer, lung cancer risk also is increased by exposure to secondhand smoke, environmental exposures, such as radon, workplace toxins (e.g., asbestos, arsenic), and air pollution. The risk of lung cancer can be reduced by quitting smoking and by eliminating or reducing exposure to secondhand smoke and environmental and workplace risk factors. The National Lung Screening Trial has shown that screening current or former heavy smokers with low-dose helical computed tomography (CT) decreases their risk of dying from lung cancer. Standard treatments for lung cancer include surgery, radiation therapy, chemotherapy, targeted therapy, laser therapy, photodynamic therapy, cryosurgery, endoscopic stent placement, and electro cautery.

    Lung cancer is “the uncontrolled growth of abnormal cells in one or both lungs”. These abnormal cells do not carry out the functions of normal lung cells and do not develop into healthy lung tissue. As they grow, “the abnormal cells can form tumors and interfere with the functioning of the lung, which provides oxygen to the body via the blood”. There are two major types of lung cancer, non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC). Staging lung cancer is based on whether the cancer is local or has spread from the lungs to the lymph nodes or other organs. Because the lungs are large, tumors can grow in them for a long time before they are found. Even when symptoms—such as coughing and fatigue—do occur, people think they are due to other causes. For this reason, “early-stage lung cancer (stages I and II) is difficult to detect. Most people with lung cancer are diagnosed at stages III and IV. Non-small cell lung cancer accounts for about 85 percent of lung cancers”(Lung Cancer 101.). The most common form is called Adenocarcinoma.…

    Lung cancer: Lung cancer is the uncontrolled growth of abnormal cells that start off in one or both lungs but is usually in the cells that line the air passages. The abnormal cells do not develop into healthy lung tissue, they divide rapidly and form tumours. It is health concern as "Doctors in Britain are 'missing opportunities ' to spot lung cancer at an early stage," BBC News reports. A study found around a third of people with the condition die within 90 days of their initial diagnosis. http://www.nhs.uk and because there are usually no signs or symptoms in the early stages of lung cancer it is hard to diagnose so more people are dying from this cancer. Lung cancer is on the increase especially in women because of the sharp decrease in the incidence of male lung cancer over the past two decades reflects the decline in smoking prevalence among men. ‘Female smokers are also twice as likely to develop lung cancer as male smokers’ http://www.nhs.uk it is on the increase becuase…

    Smoking causes the majority of lung cancers in smokers. The amount of lung cancer is powerfully connected with cigarette smoking, with about 90% of lung cancers rising ,as a result of tobacco use. The risk of lung cancer rises with the number of cigarettes smoked over time; doctors state to this risk in terms of pack-years of smoking history. Doctors believe smoking causes lung cancer by damaging the cells that mark the lungs. When one breathes in cigarette smoke, which is full of cancer-causing materials, changes in the lung tissue begin almost rapidly. In the beginning one’s body may be able to heal this harm. Even so, with each frequent exposure, normal cells that line one’s lungs are gradually damaged. As time passed, the damage leads cells to act oddly and finally cancer can progress.…

    When I was 14 my mother was diagnosed with lung cancer, which had quickly spread to her bones, then brain. I was so lost and confused; my mother never smoked a day in her life. She was a healthy woman who ate right and exercised regularly, the doctors gave her 6 months to live, and I lost her at 16. Although, there are so many people in the world who do not smoke and develop lung cancer, there’s many ways a non-smoker can get lung cancer: environmental, second hand smoking, as well as some other natural effects that can cause a person to develop lung cancer.…

    First of all, most people get lung cancer. For example, according to the article What Causes Lung Cancer states “That smoking causes about 90% of all lung cancer” (pg. 1). That means smoking causes the majority of lung cancer. For instance, the American Lung Association states “It is a proven fact that you are 23 times more likely for women and 13 times more likely for men to get lung cancer compared to people who don’t smoke.” It is more…

    Chronic obstructive pulmonary disease (COPD) is a common respiratory condition characterized by airflow limitation currently affecting more than 5% of the population and is associated with high morbidity and mortality. In the US COPD is ranked 3rd in cause of death responsible for killing more than 120,000 individuals per year. The National Health Interview Survey reports the prevalence of emphysema at 18 cases per 1000 persons and chronic bronchitis at 34 cases per 1000 persons. In the past males COPD was more prevalent than females but with an increase in women smoking there is less of a gap between sexes.…

    For example, in the nineteenth century, lung cancer death was low because tobacco was smoked in pipes and cigars. However, in the 1920’s, when tobacco was put in cigarettes, death from lung cancer increased (Cockerham, 2005). For smokers in the 1920’s, this meant a higher prevalence of lung cancer than those born in the nineteenth century. After accounting for age at time of cessation; there is a significant difference in life expectancy. When a smoker stops at age 30, they experience all the health benefit of a non-smoker; at 50, they get half the benefit; and at 60, they will gain 3 years (Cockerham, 2005).…

    “Lung cancer continues to be the leading cause of death in both men and women in the US, with over 158,900 deaths in 1999. Worldwide, lung cancer kills over 1 million people a year. Extensive prospective epidemiologic data clearly establish cigarette smoking as the major cause of lung cancer. It is estimated that about 90% of male lung cancer deaths and 75–80% of lung cancer deaths in the US are caused by smoking each year” (Hecht, 1999). Clearly, lung cancer is an important and widespread disease that constitutes a major public health problem. This was not always so. Some 150 years ago, it was an extremely rare disease. In 1878, malignant lung tumors represented only 1% of all cancers seen at autopsy in the Institute of Pathology of the University of Dresden in Germany. By 1918, the percentage had risen to almost 10% and by 1927 to more than 14%. In the 1930 edition of the authoritative Springer Handbook of Special Pathology it was duly noted that malignant lung tumors had begun to increase at the turn of the century and perhaps even more so after World War I and that, possibly, they still were on the increase. It was also noted that while most lung tumors occurred in men, there seemed to be a steady increase in women. Duration of the disease, from being recognized until death, was usually from half a year to 2 years and in practically all cases there had been a long history of chronic bronchitis.…

    With information gathered between the years of 1973 and 2007, the unfavorable lung cancer trend in white women born after circa 1950 in the southern and Midwestern states. Research showed that there was a decline in age-specific lung cancer death rates among women in the US slowed in those who were under the age of 50. This indicated that there was a low level recommendation for additional interventions that promote the end of smoking in high-risk populations. This was because it possibly could lead to a raise in the mortality trends not only for lung cancer but for additional smoking-related disease as well.…

    Lung cancer is the leading cause of cancer death in the United States. Identifying factors associated with stage of diagnosis can improve our understanding of biologic and behavioral pathways of lung cancer development and detection. We used data from a prospective cohort study to evaluate associations of demographic, health history, and health behaviors with early versus late stage at diagnosis of non-small cell lung cancer (NSCLC). This literature will give differences between smokers and non-smokers,…
