...Pollution cause Lung Cancer cases Many people who suffer from Cancer have lived in the environment with lost of toxins around them. There are many sources of such toxins, and some of them are Tobacco and Car emissions. The government has recently tired to prevent people from smoking, In 2009 President Obama came out with an act called Tobacco control Act of 2009 and said, “ The legislation takes measures to prohibit tobacco companies from marketing to children such as making candy flavored cigarettes. It also further limits misleading advertising such as the use of word such as "light" with tobacco products.” As you can see that the government of America and also the government of Canada are trying their best to prevent young people and old from smoking and preventing the retailers selling tobacco to people under age or below 19-20. As I was researching for my project, I came across very interesting articles but they were all different from each other, some said that tobacco and pollution (car emission) are the cause of Lung cancer cases, or that no they are not, or that the rates have gone up for tobacco and car sales, or some would say they haven’t. I tired my best to collect the best of the best. It is suspected that tobacco with its negative reputation that is the larger causes of lung cancer, but other says that car emission is also a cause of lung cancer, so I decide to pick this study and find that data’s for which is really the cause of lung cancer or nether are the...

...Smoking and Lung Cancer Most people are aware of the fact that smoking causes lung cancer but people hardly know how or why the cancer develops. What does tobacco contains that gives the smoker the deadly disease of lung cancer? How many packs a day and for how long does a person have to smoke in order for him or her to develop this cancer? Are there any other conditions that are caused by smoking besides lung cancer? According to Jonathan Foulds in the article “Smoking and Lung Cancer,” the smoke contains dangerous chemicals such as benzopyrene and methylnitrosamino which are deposited into the lungs. Further, the chemicals cause DNA damage, oxidative stress and inflammation which end into malignant tumor growth (Foulds). Lung cancer destroys the respiratory tract from the mouth to the alveoli; in addition, major organs of the body are affected. Symptoms of lung cancer are coughing with blood in sputum, fever, and chest pain (Foulds). There are three main methods by which lung cancer may be diagnosed. According to Mark H. Beers of The Merck Manual of Medical Information, an x-ray of the chest, CAT scan, or biopsy may be done to diagnose lung cancer. Lung cancer is usually detected at a late stage, which does not give an individual many options for treatment. The treatment options include quitting smoking, radiation therapy, chemotherapy, oxygen therapy, and surgery (Beers). The purpose of this paper is to examine smoking and lung cancer by summarizing two articles on the topic...

...Chronic Disease Description of Lung Cancer: Lung cancer disease develops inside the lung tissue, specific within the cells that line the air passages. Lung Cancer has two principal developments: non-small cell and small cell. The actual diagnosis is created by how the lung cells and cancer cells materialize under a microscope. Risk factors for lung cancer: The great number of all lung cancer affecting situations are caused by smoking cases are smoking nicotine in which is toxic. The carcinogens in cigarette smoke cause physical harm to lung tissue. If a human being smokes for a continuing period of time, the impairment can cause the cells in the lung living tissue to act irregular, which can grow and divide into cancer over time. The definition of small cell lung cancer is most often seen in excessive smokers. Non-small cell is most frequently often seen in consistent smokers and includes numerous types of lung cancers. The risk factors for lung cancer embrace smoking, being visible to secondhand smoke, a family history of cancer particularly lung cancer, excessive use and abuse of alcohol and having been unprotected to asbestos, or other hazard chemicals. In many different cases, the symptoms of lung cancer do not occur during the early stages of life cycle. Most patients do not encounter the symptoms of lung cancer until the cancer is in a leading period. The symptoms of lung cancer comprise persistent cough, harshness, breathless, coughing up blood, chest discomfort and...

...Group 6: HPV as a leading cause of Cancer Human papillomavirus (HPV) was founded in the 1950s as a virus infection that is associated to many cancers. It is primarily transmitted through sexual contact and less intimate skin-to-skin contact. Preventions have been implemented to raise awareness of the virus. The first vaccine for HPV approved as a widespread use in the US was in 2006. The virus acts to infect the keratinocytes in the skin and mucosal membrane. Other areas the HPV acts as a carcinogen are the cervix, anus, penis, vulva, vagina, oropharynx, benign genital and cutaneous warts, respiratory papillomatosis, and nasal or oral papilloma. Some researchers have concluded that the HPV infection which is more common during the active period of age is directly related to certain cancers. Researchers have found that HPV is associated with certain types of cancers and also have found that HPV can have no association with certain cancers. The research we did will explain the various cancers associated with HPV and attempt to answer the question “is HPV the leading cause of cancer?” In the United Stated and around the world, cancer is and continues to be a very serious disease that affects millions of people. Head and neck cancers are “the sixth most common cancer in the world” (Lajer et al. 2012). While the link between HPV and cervical cancer has been established; it is still unclear to researchers how HPV is related to head and neck cancer. The authors assert that alcohol...

If left untreated, this growth can spread beyond the lung by process of metastasis into nearby tissue or other parts of the body. Most cancers that start in the lung, known as primary lung cancers, are carcinomas that derive from epithelial cells. The main primary types are small-cell lung cancer (SCLC), also called oat cell cancer, and non-small-cell lung cancer (NSCLC). The most common symptoms are coughing (including coughing up blood), weight loss, shortness of breath, and chest pains.[1] The most common cause is long-term exposure to tobacco smoke,[2] which causes 80–90% of lung cancers.[1] Nonsmokers account for 10–15% of lung cancer cases,[3] and these cases are often attributed to a combination of genetic factors,[4] and exposure to; radon gas,[4] asbestos,[5] and air pollution[4] including second-hand smoke.[6][7] Lung cancer may be seen on chest radiographs and computed tomography (CT) scans. The diagnosis is confirmed by biopsy[8]...

...What is Lung Cancer? Lung cancer is cancer that usually starts in the lining of the bronchi (the main airways of the lungs), but can also begin in other areas of the respiratory system, including the trachea, bronchioles, or alveoli. It is the leading cause of cancer death in both men and women. Lung cancers are believed to develop over a period of many years. Nearly all lung cancers are carcinomas, a cancer that begins in the lining or covering tissues of an organ. The tumor cells of each type of lung cancer grow and spread differently, and each type requires different treatment. “About 85 percent to 90 percent of lung cancers belong to the group called non-small cell lung cancer” (University Hospitals, 2011). Lung cancers are generally divided into two types: Non-small cell lung cancer is much more common than small cell lung cancer; Small cell lung cancer, sometimes called oat cell cancer because the cancer cells may look like oats when viewed under a microscope, grows rapidly and quickly spreads to other organs. It is important to find out what kind of lung cancer a person has. The different types of carcinomas, involving different regions of the lung, may cause different symptoms and are treated differently. Lung cancer usually does not cause symptoms when it first develops, but they often become present after the tumor begins growing .Each individual may experience symptoms differently .A cough is the most common symptom of lung cancer. Other symptoms include: constant...

...lung cancer Lung cancer is one of the main causes of death in men and women. People think that the cause of lung cancer is only smoking which in cases it is the main cause of this specific cancer but there are other ways to get lung cancer. Another way you can catch lung cancer is second hand smoke someone can be so healthy and yet be around someone and easily get lung cancer. There are two types of lung cancer small cell lungs (SCLC) and the other is non-small cell lung cancer (NSCLC). Doctors say that (SCLC) is better to treat than (NSCLC) because (SCLC) spreads more slower and more able to catch then (NSCLC). But just because doctors can find it doesn’t mean they find it in time to treat the cancer in time. Lung cancer prognosis...

...CAUSES OF LUNG CANCER Lung cancer is a disease in which a primary cancer (the original site where the cancer occurred) develops in the tissue of the lungs. Lung cancer was first described by doctors in the mid 1800's. At the turn of the century, it was still considered a rarity ;that has changed dramatically. What has not changed is the difficultly of detecting lung cancer in its earliest stages when it has the greatest chance of being successfully treated. "Lung cancer is the leading cause of death from cancer among both men and women, with 168,000 new cases in 1992 and 146,00 deaths" ;(Winawer 283). "If you fall into the following categories of people who have been heavy smokers, you have the greatest chance of being diagnosed with lung cancer: a male over 60 ;someone who has smoked one for more packs of cigarettes a day for 20 years or longer ;someone who began to smoke before the age of 20 and is still smoking: a worker in a industrial plant with a high risk material, such as asbestos, who also smoke. Someone who has persistent or violent smokers cough ;someone who does not smoke but is frequently exposed to unnecessary passive smoke" ;(Cooper 114-120). Numerous studies all over the world have shown a link between cigarette smoking and lung cancer, as well as other cancers, with an increase in cigarette smoking followed by an increase of lung cancer. Most of these studies involve the testing of non-smokers and smokers to see how things can affect them differently and...

...Occupational lung cancer and smoking: a review in the light of current theories of carcinogenesis ALAN C. CHOVIL, MA, MB, B CHIR MPH, DAB PREy MED This paper considers modern theories of carcinogenesis as they apply to the induction of lung cancer by tobacco smoking and occupational exposure to carcinogens. Some of the known and postulated factors affecting carcinogenesis are discussed, with particular reference to syncarcinogenesis and thresholds. Factors affecting the intensity of smoking exposure are reviewed, and the generally accepted occupational lung carcinogens are listed. Relative risks for the various carcinogens according to smoking status (where known) are presented. The carcinogens are considered individually, and known or postulated interactions with smoking are discussed. It is concluded that the effects of lung carcinogens can be explained on the basis of current theories that support a rational definition of priorities for the prevention of occupational lung cancer.

...Cancer is one of the most terrifying medical conditions in the world, and it has touched nearly everyone's life in one way or another. It can affect any part of the body and there is no way to exactly predict who will or will not develop it, or when it will appear. Lung cancer is the leading cancer killer of women and men in the U.S. About 170,000 people in the United States are diagnosed with lung cancer each year. British scientist Sir Richard Doll discovered the connection between smoking and lung cancer. Doll published a study in 1950 that confirmed that "smoking was a major cause of lung cancer." Doll was knighted in 1972 for his work, which saved millions of lives. Lung cancer appears when a cycle of mutations in normal lung cells cause them to become abnormal and grow out of control. These changes can occur anywhere from the windpipe, down to the small air sacs in the area around the edge of the lungs where oxygen exchange takes place. Lung cancer is an uncontrolled, very deadly division of cells in the lung. Lung cancer is a disease where cancer cell go out of control taking over normal cells and organs cells in the body. There are two main types of lung cancer; non-small cell lung cancer and small cell lung cancer. There are many symptoms that are hard to notice in the early stages of lung cancer. Doctor’s use special machines to identify the awfulness of each stage. Treatments and cures are different in each person case. Small cell lung...

...Smoking and Lung Cancer Smoking and Lung Cancer The devastating cause of lung cancer is creditable to cigarette smoking. Introduction Fatalities due to cancer are widespread around the globe. One of the leading cancers, worldwide, is lung cancer affecting both men and women; killing more than 1 million people in a year, according to estimation. Smoking has by and large contribution in the cause of lung cancer. Obviously, lung cancer is a significant and prevalent disease that comprises a key public health problem. It is evidently established by widespread epidemiological data that cigarette smoking is the main motive of lung cancer. Overall, 75- 80% of lung cancer fatalities and particularly 90% deaths among males are contributable to smoking in United States every year. (Hecht, 1999) Discussion There is a dose-response association exist among smoking and lung cancer, and the possibility for lung cancer amplifies with duration of smoking, quantity of smoked cigarettes, age at beginning of smoking, unfiltered cigarettes’ usage, content of tar and nicotine, and extent of intake. In 1956, a pivotal trial was performed by Doll and Hill which illustrated that a cessation in smoking minimizes the potentiality of lung cancer relatively to those who keep on smoking. Reproduction of this verdict by Pathak et al. in a study in 1986 weighed against cases and controls more than 65 years of age to less than 65 years of age to those and furthermore displayed that there was...
