Introduction Doctors and scientists have studied the study of cancer, also known as oncology, around the world. Technology and the increase of understanding of cancer have made it one of the most evolving areas in modern science. Cancer begins when cells in a part of the body start to grow uncontrollably. Lung cancer is the prominent cause of cancer death around the world and kills over 1 million people per year. It is an important and widespread disease that composes as a major public health problem, and if left untreated becomes very malignant.
Etiology
Lung cancer is strongly associated with cigarette smoking, both from the actual smoker and secondhand, although there are cases in which someone that has never smoked or experienced secondhand has had lung cancer. Pipes and cigar smoking are also factors of lung cancer, but the risks are not as high as cigarettes. Another cause known for lung cancer is asbestos fiber. Asbestos fibers are silicate fibers that persevere in lung tissues after exposure to asbestos; which is something that can be picked up in a workplace where thermal and acoustic insulation is used. Smoking cigarettes increases the risk of developing asbestos-related lung cancer in workers. Even though lung cancer is more commonly associated with tobacco, there are cases in which non-tobacco smoker also get lung cancer. Genetics may play a big part in this role, leading researchers to find a region in the long arm of chromosome number 6 that is likely to

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.
Lung cancer is a genetic and acquired disease. Lung cancer is genetic because cancer in general is caused by changes to the genes that control the way our cells function, especially how they grow and divide. All of these changes include mutations in the DNA that makes up our genes. Genetic changes that increase cancer risk can be inherited from our parents, if the changes are presents in germ cells. Which are the reproductive cells of the body, those are the eggs and the sperm. Lung cancer is also acquired because as the result of errors that occur as cells divide a person’s lifetime or exposure to certain chemicals. Some examples of these chemicals are found in tobacco smoke, radiation, UV rays from the sun that damage DNA. “In general, cancer cells have more genetic changes than normal cells. But each person’s cancer has a unique combination of genetic alterations.” Some of these changes may be the result of cancer, rather than the cause. As the cancer continues to grow, additional changes will occur. Even within the same tumor, cancer cells may have different genetic changes.
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 is the leading cause of cancer death and the second most diagnosed cancer in both
Although Tumors can be benign or malignant, but when we mention cancer, we usually mean those deadly malignant tumors. Smoking is no the only cause of lung cancer, there are many other gases and chemicals that causes lung cancer such as, Radon gas, Asbestos, and air pollution are also main causes of lung cancer. Those chemicals and gases can damage hair like projections on air way cells called Cilia. Cilia usually sweep out any abnormal gases or smoke and when cilia is being destroyed, those gases may cause lung
Lung cancer is one of the most common types of cancer in the world. There are a variety of causes for this particular cancer, the most common one being smoking, or anything related to tobacco. What smoking does is damage the cells in the lungs. When you then inhale the smoke, the cancer-causing substances in the smoke begin to affect the lung tissue. Your body can at first naturally fix the damage, however if the smoking continues, the cells will continue to suffer and behave abnormally, which is when the cancer begins to take over. As one would guess, smoking directly has a much higher risk-rate than not smoking. There is however something called passive (second-hand smoking), in which case being around a heavy smoker can actually have similar
One of the leading and most avoidable risk factors of lung cancer is smoking. In both males and females smoking is linked to a higher incidence of lung cancer at an increase of 23% and 13% respectively. Smoking not only increases the likelihood of lung cancer, but has shown a correlation in higher risk of other cancers such as oral, laryngeal, pharyngeal, esophageal, pancreatic, ovarian, and multiple more. As a whole,
Lung cancer is a kind of cancer that begins in the lungs. Lungs are the spongy organs in the chest that are responsible for taking in oxygen when one inhales and releases carbon dioxide when one exhales. Lung cancer is the principal causation of cancer related deaths in the United States, amongst both women and men. It claims more lives annually than does breasts, ovarian, prostate and colon cancers, all combined. People that smoke have the highest chances of suffering this ailment. The risk of this form of cancer increases with the number of cigarettes one smokes and the duration that one smokes. Lung cancer causes the demise of more than one million people worldwide
The most common cause of lung cancer is smoking cigarettes. 80% of people who have lung cancer got it from smoking. The longer you smoke cigarettes the better chance of getting lung cancer. Smoking at a young age increases the chance of getting lung cancer more then starting to smoke as an adult. The sooner you quit, the better your life will be. Passive smoking (secondhand smoking) can give you lung cancer if exposed for a long time to it.
To start with, One of the major causes of Lung Cancer is smoking cigarettes. Cigarettes contain some deadly chemicals the causes multiple cancers. (According to Lynne Eldridge, MD 2016) “Smoking is responsible of ninety percent of Lung Cancer.” Any type of smoke is supposed to be inhaled especially cigarette smoke. Cigarette smoke causes more than just cancer. Smoking cigarettes can cause chronic bronchitis and also a recurring cough that you just can
It is estimated that smoking plays a role in about 90 percent of lung cancer cases. The longer one smokes, the more likely he or she is to develop lung cancer. Cigarette smoke contains 70 chemicals that are known to cause cancer. Even if a person smokes occasionally, he or she is still at a greater risk for developing lung cancer.
For this project I decided to research lung cancer. My grandfather had lung cancer for years and is cleared for now. One main cause of lung cancer is smoking. Heavier smokers have a bigger chance of getting this disease unlike light smokers. Young smokers also have a increasing risk of getting lung cancer too. When you are exposed to gases or if you are a welder; have an increasing chance. People ages 45 and 75 get lung cancer primarily.
Lung cancer is a disease that effects the lungs. This type of cancer initiates in the lungs. The lungs are two spongy like organs in the chest that take in oxygen when you inhale and release carbon dioxide when you exhale. People who smoke have the greatest risk of lung cancer. The risk increases with the numbers if cigarettes you have smoked. If a person quit smoking, they can reduce the chances of developing 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. Lung cancer has the lead in the most cancer deaths in the United States, with over 158,900 deaths in 1999, and worldwide, lung cancer kills over 1 million people a year.
Lung cancer takes the lives of many at a young age and the cause isn’t always clear as of how this disease was contracted. The most popular idea of what causes lung cancer since early times has been using tobacco. Tobacco contains nicotine which is a highly addictive drug that gives a temporary feeling of relaxation. When people get addicted to nicotine, it becomes incredibly difficult for the victims to stop smoking. According to Brody, Lung cancer has been shown to take the lives of more people compared to any other form of cancer and this is the case since lung cancer is associated with life style. New information regarding lung cancer has shown that about one-fourth of those victims who are diagnosed didn’t obtain it through first hand smoking. People can obtain this illness through an “unlucky” combination of genetics (Brody).
