Lung Cancer : The Highest Mortality Rate

What are lung cancers? Lung cancers are the abnormal cells which grow in uncontrolled manner in one or both lungs. They do not function as normal lung cells and do not develop into healthy lung tissue. The abnormal cells can grow, form tumours and interfere with the normal functions of the lung (Lungcancer.org, 2015). Lung cancers can be divided into two major types, namely non-small cell lung cancers (NSCLC) and small cell lung cancers (SCLC). NSCLC can be further classified into three main subtypes, namely adenocarcinoma, squamous-cell carcinoma and large-cell carcinoma (Longo & Harrison, 2012). Lung cancers can be diagnosed by chest X-ray, computerised tomography (CT) scan, positron emission tomography-computerised tomography (PET-CT) scan, bronchoscopy and biopsy (Nhs.uk, 2015). Unfortunately, lung cancers are often diagnosed at the later stages. This is due to the unrecognisable symptoms and warning signs at the earlier stages. NSCLC are often diagnosed at stage IV which accounts for 30-40% of cases whereas 60% of SCLC is diagnosed at stage IV. Lung cancer usually originates from the cells lining the bronchi, bronchioles and alveoli. Carcinogens especially tobacco smoke will alter the gene expression of the normal human lung cells, resulting in cell mutation. The proto-oncogenes will be converted to mutated form, oncogenes. Mutation leads to the decreased expression of the tumour suppressor genes. This results in uncontrolled cell proliferation, cell

Throughout life, many individuals experience difficulties due to growing up in everyday life. While going in depth of the human life, it is discovered that there are many diseases and disorders that affect humans’ everyday functions. A very popular disease that has traumatically affected the human body is cancer. Cancer is a disease that spreads throughout your body in many ways. The purpose of cancer is to attach to a blood cell in your body and cause a plague within itself, causing the body to initially shut down and die. This disease contains many forms and have many causes to it. However its main goal is to destroy the human body.

However, there are stages in the lives of all humans when the body finds itself in a position where it is no longer able to defend itself against ailments and diseases and eventually may even lose the battle. One such disease which claims many lives every year in this manner is Cancer. So far so, there has been no cure for Cancer but some medicines and treatments are now available which can slow down and in some cases can even alter the effects of Cancer, depending on the stage at which the disease is at that moment. For this paper however we would concentrate on Lung Cancer and its effects.

Lung cancer can be caused by multiple factors and many factors can work together to cause someone to have lung cancer. Besides smoking, radon, secondhand smoke, the environment and someone’s occupation can all cause lung cancer. As we already know smoking is the number one cause of lung cancer cases worldwide and over forty-three million people just in the United States smoke cigarettes. There are more than fifty chemicals in tobacco smoke that are ingested each time someone smokes. Some of these chemicals include benzene (which can be found in pesticides and gasoline), Formaldehyde (which preserve dead bodies), pesticides (which are found on lawns and gardens) and Tobacco-specific N-nitrosamines (Martin, 2012). When a person inhales the chemicals in cigarettes, they inhale thousands of poisons, toxic metals, and

Lung Cancer. Two words that nobody wants to hear. A dreadful and frightening disease that can seriously injure a human being. A horrible disease that can kill somebody that doesn’t deserve such a thing. “Lung cancer is a serious health problem that

Lung cancer is a type of cancer is found in men and women lung cancer have something to do with your lungs. Your lungs which help pump oxygen into your body and also release carbon out of your body which helps you live because you need oxygen. Lung cancer is a common cancer in ages 60 and up it can also be found in any age but is most commonly in 60 year olds and older. Lung cancer is the leading cause of cancer deaths in the U.S. in both men and women. Lung cancer is also one of the most preventable kinds of cancer, but smoking is mainly the leading cause of lung cancer.

The cancers that are most common in men's are lung cancer, prostate cancer, and colon cancer. Lung cancer kills more over 50,000 men a year. More men are likely to get lung cancer because in general men smoke more than women. Non-small cell lung cancer referred as NSCLC. This is a dangerous disease that can immediately affect your quality of life by causing breathing difficulties. Two types of lung cancer have different subtypes that can affect your overall prognosis. The main subtypes of NSCLC are adenocarcinoma which starts in the outer part of lungs. Squamous cell carcinoma where it starts in the middle portion of lungs, and undifferentiated carcinoma where its fast-growing cells that can start in any portion of the lungs. The expectations of survival rate of having NSCLC is on a five year survival rate; which lung cancer can not be reversed. It was suggested that loss of control of cell cycle checkpoints is a common occurrence in lung cancers, and support of the idea that functional cooperation between different cell cycle inhibitor the proteins constitutes to another level of regulation in cell growth control and tumors suppression. Present review of literature mainly describes the cell cycle control, the lung cancer molecular pathogenesis, the catalog of known genetic alterations and the recent advances in the global expression profiles of lung tumors. As lung cancer cells are not

Cancer is the leading cause of death in the world. An astounding average of 1.6 million deaths occur due to lung cancer every year, making it the most common type of cancer worldwide (1). Lung cancer is broadly classified into two types: small cell and non-small cell lung carcinoma (NSCLC). 85% of all lung cancer cases are NSCLC. NSCLC has several different histologic subtypes, some of which are: squamous cell carcinoma, large cell carcinoma, and adenocarcinoma. Of the three, adenocarcinoma accounts for more than 50% of all NSCLC cases, making it the most common subtype of NSCLC (2).

Our respiratory system is very critical part of our body. It consists of the airways which are comprised of the nose, mouth, pharynx, larynx and trachea, the lungs and the muscles that allow us to breathe. This system supplies oxygen rich blood to our body and removes carbon dioxide. The main organs that carry out this gas exchange are the lungs.

Lung cancer is the deadliest form of cancer in the United States. It kills more men and women than a number of cancers combined. The disease has many risk factors that affect the chances of obtaining it. The leading risk factor is one that can be avoided, that is smoking. This paper will look at methods to find, diagnose and treat lung cancer. It will show ways to reduce chances of getting lung cancer and also look at preventive methods used.

Lung cancer is the leading cancer killer of men and women in the U.S. The main cause of lung cancer is smoking. (Health Risks, n.d.) Smoking weakens our body’s immune system due to the chemicals (carcinogens) that are found in cigarettes. People don’t realize how damaging these chemicals are in their bodies or maybe they do and just don’t think it will happen to them. Smoking not only causes cancer it, also causes other health issues such as heart disease, COPD, obesity and many others. The sad thing is cigarette companies know they are slowly killing people, yet they continue to advertise and sell their products. Although, this isn’t very hard for them to do with all the help they get from actors and actresses making films with them smoking. This is why kids start smoking at such a young age, because they see actors/actresses they idol doing it.

Lung cancer is a deadly class of disease that is specifically composed of uncontrolled cell growth in the pulmonary extremities of the body (Crosta. 2009). When left untreated, the abnormal lung tissue eventually develops into life-threatening tumors (Crosta, 2009). Lung cancer is a disease that is particularly caused by smoking, nonetheless there are cases where it is simply developed naturally. The disease can severely harm the health of an individual over the course of years. In addition, researchers have determined that lung cancer is the leading cause of cancer deaths among both men and women (Mayo Clinic Staff, 2014). As of today, about 210,828 people in the United States have been diagnosed with lung cancer (CDC, 2015). In 2012, about

As usual he feels weak and unrested, he has become acquainted to the discomfort in the chest as bronchitis has become a recurring issue. However, the irritation in the chest seems aggravating than normal. Richard thinks nothing of it and puts a cigarette in his mouth as he prepares to leave for a long fourteen hour shift as a truck driver. He catches a glimpse of himself on the mirror and notices lumps near the surface of the body. As Richard ponders the possibilities of what it might be he starts to realize recent happening that got him concerned. He has been coughing up blood, has had little to no appetite and has had sounds of wheezing from the chest. The long time heavy smoker finally decided it what time to get checked out by the

Lung Cancer is by far the most common cause of cancer related death in the world. Every year more than 200,00 Americans are diagnosed with lung cancer and over 100,000 Americans die from lung cancer.

Lung cancer is one of the most significant and preventable causes of death in the United States and other developed countries today. Some states within the US have higher instances of lung cancer than others, and there are various factors that affect that. For the state of Tennessee, which will be the focus of this paper, the most current year for which lung cancer statistics are available is 2007. According to the CDC, there were 78.4 to 97.7 people per 100,000 who got lung cancer in Tennessee in 2007 (CDC, 2010). Among people in that state who had lung cancer, 56.8 to 74.6 per 100,000 died in that same year (CDC, 2010). The Tennessee Department of Health also released 2007 figures on the 10 leading causes of death in that state, which were:
