Lung Cancer: Beware of Death

1. Smoking is One of the biggest causes of cancer in the world. For many years of researching links between smoking and cancer are now very clear.

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 is the most common cancer-related cause of death among men and women. Lung cancer can be undetected for many years causing it to become more dangerous and possibly fatal. There is not cure for lung cancer or any cancer, but if detected in an early stage the lung cancer can be detected, treated, and hopefully terminated. There are many new and developing treatments being tested now that may save lives in the future. Through understanding what the lung cancer is, doctors can easily diagnose and assess cancer patients.

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

Lung Cancer is a disease which consists of uncontrolled cell growth in lung tissues. Lung cancer consists of two types, Non-small cell lung cancer, and small cell lung cancer. (NSCLC) is the most common type of lung cancer. The bronchi are the large air tubes leading from the trachea to the lungs that convey air to and from the lungs, and where most lung cancers begin. The body normally maintains cell growth only

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 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.

Cancer, it can affect anyone; it can affect any part of the body but what is it? Cancer results from the abnormality in the body's cells. This occurs when the cells divided and grow. Disruption in the system of the growth and division of a cell results in an uncontrolled division and proliferation of cells that form a mass which leads to cancer. The patient outcome for cancer is different for everyone, but it is also different with each type. In the respiratory department, a major type of cancer we will deal with is lung cancer. Lung cancer, however, has different types and stages, but for this paper, we are going to talk about Stage IIIA non-small cell lung cancer (NSCLC). In the article titled “Stage IIIA Non-Small Cell Lung Cancer” it states

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 is a tumor that affects either one or both of the lungs.A primary cancer begins in the lungs and a secondary cancer begins in another place in the body and makes its way up towards the lungs. Lung cancer is the 5th most common cancer. In Australia 59% of males were diagnosed were as 41% of Australian females were diagnosed.

The Lung Cancer is the major of the cancer death. According to the data from Australian government on 2011, it showed the death rate is far higher than other disease, all because its early symptoms are non-evident, that lead to most of the sufferers are often missed the best time for treatment. Lung Cancer occurs when there has the uncontrolled cells growth in the lung tissues, these cells normally lining on the air passages, then forms a tumour which can be small-cell carcinoma or non-small-cell carcinoma. The five year survival rate of the person who with Lung Cancer is less than 14%(EWTERY).

We should know the meaning of cancer particularly before be informed of the definition of lung cancer. Cells are a big part of our body, most of which are able to split and replicate themselves so the body can

Lung cancer is one of the leading causes of death around the world because of its high mortality rate. Smoking is a very common risk factor for lung cancer and other pulmonary diseases. Asthma, pulmonary tuberculosis (TB), and pneumonia are diseases in the lungs, which cause inflammation in the passages of air the lungs and are said to increase the risk of lung cancer, these diseases also affect people at any age.

Lung cancer has many causes, symptoms, and effects which occur throughout the body and have a substantial impact on the function within the human body. The five main topic that will be discussed is providing background on lung cancer, causes of lung cancer, symptoms and treatment, the effects that lung cancer has, and what researchers are doing today to cure and prevent lung cancer. Providing background information on lung cancer will work towards the rest of the paper so theres a better understanding, explain the two main stages of lung cancer, and specifically the different stages. Talking about the causes of lung cancer will include explaining about the carcinogens and ways to help prevent lung cancer for future instances. With symptoms and treatment this will include medicines used for lung cancer, surgeries performed to help or cure it, therapy used, and lastly signs to know when you have lung cancer. For the subject of the effects that lung cancer has it will include, side effects, how you might feel, internal conditions, and the after effects when the lung cancer is cured. Finally the last topic that will be covered is what researchers are doing today to cure and prevent lung cancer, this will talk about new treatments being looked into, early detection, immune treatments, and New Therapy.

Cancer is a disease that results to an abnormal growth of the cells and form tumors which may spread throughout the body leading to the body malfunction (Radon & Raymond, P4). While there are various types of cancer such as lung cancer, prostate cancer, breast cancer among others, this paper will focus on lung cancer and will major in the following:
