Lung Cancer : The Primary Reason For Americans

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

Brief Description: Lung cancer, as with all cancers, is an uncontrollable increase of cells. It happens within the lung tissue, but it could also go on to affect other nearby tissue and spread to further out than just the lungs.

Over decades, lung cancer globally continues to be the leading killer in both genders. In the United States, smoking is responsible for 90% lung cancer deaths in men and about 80% in women. About 15 decades ago, lung cancer was not considered as the leading killer because it was an extremely rare disease about 1% in total of cancer cases. However, by the year 1927, the percentage increased into 14%. During World War I, many soldiers and civilians started smoking to release stress. Eventually, that made the lung cancer rate and smoking addiction in the population started to increase. In a research that published in 2001, lung cancer annually kills over one million people worldwide (Witschi, 2001). The death rate, which caused by lung cancer,

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

The number one factor for getting lung cancer is smoking tobacco. Smoking causes cancers because the tobacco changes our DNA and

The type of cancer I chose to do this paper on is lung cancer. This paper will discuss many things about lung cancer like what it is, causes, symptoms, treatments, and diagnosis.

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

Lung cancer is the leading cause of cancer deaths in the United States, among both men and women. Lung cancer claims more lives each year than do colon, prostate, ovarian and breast cancers combined.

Cancer is one of the most common lethal diseases in the medical field. Cancer is a group of cells in any part of the body that grows abnormally. Cancer in the lungs causes many vital functions to be extremely no help, or negligible altogether (Mayo Clinic Staff). Lung cancer is the leading cause of cancer deaths in the United States, among both men and women. The Mayo Clinic states, “Lung cancer claims more lives each year than do colon, prostate, ovarian and breast cancers combined” (Mayo Clinic Staff). People who smoke or have smoked for a long period of time have the greatest risk of developing cancer within the lungs. Lung cancer’s risk is directly proportional to time using cigarettes and number of cigarettes that have been smoked (Mayo Clinic Staff).

From my studies, I have been able to demonstrate several links between lung cancer and smoking. It is indeed scientifically proven, that smoking is one of few factors that develop lung cancer – in fact it is the greatest. There are several pieces of evidence that support this theory, and are included later in this report.

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 the number one leading cause of cancer deaths in the United States. Lung cancer kills more people than any other cancer, such as; breast cancer, colon, prostate, or ovarian. There are two types of lung cancer, small cell lung cancer and non-small lung cancers. These two lung cancers grow and spread differently. Small cell lung cancer tends to spread quickly and makes up about 10-15 percent of the lung cancers. Non-small lung cancer is the most common type, it attributes to about 85 percent of lung cancers. The sub types of non-small cell lungs cancer are; squamous cell carcinoma, adenocarcinoma, and large cell carcinoma. People who smoke have the greatest risk of lung cancer. If you quit smoking you can significantly reduce your chances of developing lung cancer. The overall prognosis is poor, lung cancer is usually not found until it is in its advanced stage. According to the Mayo Clinic “Five-year survival is 40% to 50% for early stage lung cancer, but only 1% to 5% in advanced, inoperable lung cancer.”

Now what causes lung cancer? Well the number one leading cause of lung cancer is smoking. According to www.webmd.com ,around ninety percent of lung cancers arise because of tobacco use. The risk of lung cancer increases with the number of cigarettes over time. Pipe and cigar can also cause lung cancer, although the risk is not as high as cigarettes. While someone who smokes one pack a day has a risk for the development of lung cancer that is twenty-five higher than a non-smoker, pipe and cigar smokers have a risk of lung cancer that is about five times that of a non-smoker.

While much research has been conducted on the causes and treatments of lung cancer, there is much to be done to help promote good health choices. The risks of smoking increase the chance of being diagnosed with lung cancer. Air pollution is also a contributor. Marketing better health choices, public awareness, and education can help prevent this disease. Lung cancer is defined as abnormal cell tissue that forms in tissues of the lungs . It is estimated that there are 224,210 new cases every year, while the estimated deaths are numbered at 159,260 per year. There are several options of treatment and are as follows: Surgery, Chemotherapy, Radiation Therapy, Immunotherapy and Vaccine Therapy. Research and advertisement has brought about much change to the public awareness.
