Lung Cancer

Lung cancer occurs when a odd cells in the lung grow in an uncontrolled way. It often spreads to other parts of the body before the cancer can be identify in the lungs. Lung cancer is 1 of the 10 most common cancers in both men and women in Australia.

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

Surgery is the most common method used to treat lung cancer followed by chemotherapy or radiation. Surgery can be used if the cancer is benign. Surgery removes the cancer inside the patient. Although surgery is the most popular method, the chance of the doctor being able to remove all of the cancer is highly unlikely. Since the cells are so small and there are thousands of them it is very difficult to remove every one. When a patient uses surgery to treat the cancer, the cancer has a good chance it can come back, because it only takes a few bad cells to spread and create a tumor.

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

Cellular / Molecular Basis: Lung cancer has two types; small cell and non small cell. The two types can be identified by their appearance when looked at with a microscope. It usually affects the cells that are lined along air passages in the lungs.

Lung cancer is a cancer that originates in the lungs. Lung cancer often goes undetected in the early stages, since symptoms don't usually present themselves until the advanced stages of the disease.

There are different types of lung cancers. NSCLC occurs when abnormal cells grow uncontrollably. The abnormal tissues multiply, and they form malignant tumors. The tumors can spread to other organs and tissues. Smokers have the highest rates of NSCLC. Prolonged exposure to radon can also cause NSCLC.

Although many people have heard about lung cancer, they don't know that there are two major types of lung cancer. The types of lung cancer are non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC). NSCLC breaks down into three different types and approximately makes up 85-90% of the cancers that patients are diagnosed with. The first type of NSCLC is adenocarcinoma. This type of cancer is usually found in smokers however it is the most common lung cancer found in nonsmokers. This cancer typically attacks younger adults and targets women. This cancer tends to develop on the outside layers of the lungs and it can be found before it spreads throughout the body. The second type of NSCLC is squamous cell carcinoma. This cancer is linked to smoking and forms in the inner airways of

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

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 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.

Cancer of the lung was nearly nonexistent in the early 1900’s. By the middle of the 20th century an epidemic became apparent throughout the United States and the rest of the world. It is primarily correlated with the widespread abundance of cigarette smoking in the world. The tobacco industry has multiplied its production immediately prior to World War I. There was a typical 20 to 30 year lagging period between the initiation of cigarette smoking and the actual tumor formation in the lungs. Lung cancer is the cancer that originates in the tissues of the lungs. It occurs when cells in the lung start to grow rapidly in an uncontrolled manner. Lung cancer can start anywhere in the lungs and affect any part of the respiratory system. Most of

Lung cancer is a type of cancer is found in men and women lung cancer have something to do with your lungs. Your lungs which help pump oxygen into your body and also release carbon out of your body which helps you live because you need oxygen. Lung cancer is a common cancer in ages 60 and up it can also be found in any age but is most commonly in 60 year olds and older. Lung cancer is the leading cause of cancer deaths in the U.S. in both men and women. Lung cancer is also one of the most preventable kinds of cancer, but smoking is mainly the leading cause of lung cancer.

Cancer can be one of the hardest battles that one must face, whether that battle is lost or won, it changes the lives of everyone involved. Lung cancer is one of the most diagnosed cancers and it affects the lining of the lungs and the ability to breathe. Lung cancer is the number one killer of men and women than any other cancer worldwide. This cancer is mostly found in smokers and this is why professionals are targeting this population for testing for diagnosing early and possibly saving a life (www.ncb.nlm.nih.gov). Lung cancer refers to the malignancies that originate in the airways or pulmonary parenchyma.
