Symptoms And Treatment Of Lung Cancer

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

Lung Cancer, like any other type of cancer, is the uncontrollable growth of cells in the lung tissue. The main causes that contribute to lung cancer include inhaling carcinogens (basically, smoking), exposure to ionizing radiation, viral infections and even air pollution. These factors basically damage the tissues lining the bronchi in the lung, leading the cancer to develop further (Vaporciyan & Nesbitt JC, 2000). Primary lung cancers that develop in the epithelial tissues of the lung are known as carcinomas and claim the top spot in terms of leading cancer-related death causes. As of 2004, lung cancer

Causes: The foremost reason for lung cancer is cigarette smoking which causes around 90% of all deaths caused by lung cancer in the world. However, smoking is not the only way to get it. The second most frequent cause of lung cancer is exposure to radon gas, which

Beneath the lungs, a slender, arch formed muscle called the stomach isolates the mid-section from the guts. When you inhale, the stomach climbs and down, compelling air all through the lungs. Lung tumor begins when cells of the lung get to be anomalous and start to become crazy. As more disease cells create, they can frame into a tumor and spread to different regions of the body. Non-little cell lung growth is a gathering of lung tumors that act likewise, for example, squamous cell carcinoma and adenocarcinoma. Side effects are a hack that won't leave, shortness of breath, weight reduction, or hacking up blood. Medicines incorporate surgery, chemotherapy, and radiation. Lung disease begins when cells of the lung get to be strange and start to become crazy. As more malignancy cells create, they can frame into a tumor and spread to different ranges of the body. Around 80% to 85% of lung growths are non-little cell lung malignancy (NSCLC). There are subtypes of NSCLC, which begin from various sorts of lung cells. Be that as it may, they are assembled together as NSCLC on the grounds that the way to deal with treatment and guess are regularly

Lung cancer is a very common to be diagnosed with and harmful to anyone who is exposed to many resources around the world: smoking (first hand and second hand) and pollution. Any resource that is made up of chemicals that are exposed into the air that people breathe, give the risk of affecting others with lung cancer. However, since smoking is the most popular way to cause lung cancer, many people are exposed to it from either firsthand or second hand. First hand smoking is when the person being affected is indirect contact with the source that is giving off the toxins, while secondhand is when the one being affected is not directly connected to the main source. Either way the chemicals and toxins that come from harmful resources soon will build up and affect one’s normal body

Lung cancer happens to be the top cause of deaths in the United States for both genders. It tends to people who smoke are at a higher risks for this type of cancer. Even people who are exposed to secondhand smoke are at risk. Others can get this cancer even if they aren't near smoke at all. Smoke is believed to cause lung cancer because it's damaging the cells that line the lungs. It causes cells to act abnormally.

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

What is cancer?-Cancer is a disease caused by an uncontrolled division of abnormal cells in a part of the body.Malignant growth or tumor resulting from the division of abnormal cells.Some of the body's cells begin to divide without stopping and spread into surrounding tissue.

Lung cancer is a type of cancer that starts on the cells lining the bronchi and other parts of the lungs. Lung cancer claims more lives than colon, prostate, ovarian, and breast cancer combined. It is thought that lung cancer starts in areas of pre-cancerous changes in the lungs. It then will develop into lung cancer over time. There are 2 main types of lung cancer, small cell and non-small cell lung cancer. Non-small cell lung cancer is the most common type of lung cancer. Symptoms of lung cancer do not usually appear until a later stage of lung cancer. Some

The risk of getting diagnosed with lung cancer increases depending on the length of time a person smoke and the amount a person smokes. People that smoke more than 5 cigarettes a day have 200 times the chance of developing the cancer than the non-smoker. Second hand smoking can also cause lung cancer. Another cause is being exposed to radon for a long time. Radon is a radioactive gas. Some environmental toxins that can cause lung cancer are asbestos, hydrocarbon products, nickel, vinyl chloride, uranium, and pitchblende. Coal tars or roofing products are some examples of hydrocarbon products. One more cause for lung cancer can be the continuous damage of lungs for any

Quit Organization (2016) stated that a Tobacco smoke is compose of thousands of chemicals and many of them are very damaging. Around 70 of them can cause cancer. Not only does smoking increase the chance for lung cancer, it is also a risk factor for cancers like the: Mouth, Larynx , Pharynx, Esophagus, Kidney, Cervix, Liver, Bladder, Pancreas, Stomach, Colon/rectum and Myeloid leukemia. Cigarettes, cigars, pipes, and spit and other types of smokeless tobacco can all cause cancer.

Most people know that smoking is one of the main causes of lung cancer. However, there are also other things that increase your cancer risk you are doing everyday. This includes breathing air full of smog to breathing the fumes from a running automobile or any gas powered engine.

Lung cancer is a condition that occurs when an abnormal cluster of cells develop inside of the lungs. Because this is one of the most common forms of cancer, it is important for everyone to learn all that they can about it. Below is a list of some of the important facts about lung cancer:

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.

Aside from the obvious cause of lung cancer, which is smoking, there are several others. However, almost all of these can be avoided. Preventable risk factors include smoking marijuana, inhaling certain chemicals like gasoline fuel or diesel exhaust, undergoing radiation therapy, and having a poor diet. But, the American Cancer Society affirms that about 87% of lung cancer cases are a result of smoking tobacco, and that some of the other 13% are caused by secondhand smoke (11). Out of all the risk factors for lung cancer, smoking has the biggest impact. This is also ironic, as smoking is the easiest factor to avoid. Theoretically this should be the least prominent factor, as it is a voluntary decision to start smoking and is easier to avoid than any of the other factors. Yet, about 47.1 million people in the United States smoke (American Heart Association), and willingly put themselves at risk for lung cancer. At the same time though, people do not start smoking just because they want to develop lung cancer later in life; there are numerous factors that play into their decision. For example, people are influenced to smoke for reasons such as peer pressure, a way to deal with stress, and people they look up to that smoke (Bonas). They think it will help them relieve stress, or fit in, and they do not think about the consequences that come with their newfound hobby. Eventually smokers find that they cannot quit, for both physical and psychological
