Research Paper On 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

A common form of cancer that is very popular today is lung cancer. Lung cancer is a very dangerous form that can cause problems in simple body functions. These simple body functions are short breath and general fatigue. Lung cancer is commonly formed from smokers that has been exposed to that activity for numerous years. Lung cancer can also be spread by being exposed to asbestos or other pollutants. This form of cancer has many risk factors to it. These risk factors are high levels of air pollution, arsenic drinking water, and radon gas. Radon gas is a gas that is highly radioactive and is very sensitive to the body. Once radon is exposed to the body, it has a very high respiration rate which initially divide its radioactive cells- causing more significant damage to the body.

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.

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

Cancer is very common throughout the United States and has shown increase numbers of cancers around the world. As the term cancer is referred to the condition where the body's cells begin to grow and reproduce in an uncontrollable manner. Cancer cells are able to invade and destroy healthy tissue, including organs. As cancer cells can sometimes begins in one part of the body before spreading throughout the entire body systems. Cancer was never a high-priority disease and was often pushed to the side due to the fact that there was no treatment, harsh conditions, and low diagnosis; but today's century we have the technology to overcome cases and able to handle them and find treatments for various cancers. There are many types of cancers that

Cancer is the leading cause of death in the world. An astounding average of 1.6 million deaths occur due to lung cancer every year, making it the most common type of cancer worldwide (1). Lung cancer is broadly classified into two types: small cell and non-small cell lung carcinoma (NSCLC). 85% of all lung cancer cases are NSCLC. NSCLC has several different histologic subtypes, some of which are: squamous cell carcinoma, large cell carcinoma, and adenocarcinoma. Of the three, adenocarcinoma accounts for more than 50% of all NSCLC cases, making it the most common subtype of NSCLC (2).

Lung cancer is the deadliest form of cancer in the United States. It kills more men and women than a number of cancers combined. The disease has many risk factors that affect the chances of obtaining it. The leading risk factor is one that can be avoided, that is smoking. This paper will look at methods to find, diagnose and treat lung cancer. It will show ways to reduce chances of getting lung cancer and also look at preventive methods used.

From all the cancers the body can be diagnosed with, lung cancer is the leading cause of death among men and women in the United States. About 14% of all new cancer cases are lung cancers, and it is likely that this percentage will continue to grow. The reason for the rise of this disease is due to one’s environment and lifestyle. And if you are not willing to change, you are at the risk of being affected with lung cancer.

Lung cancer is a deadly class of disease that is specifically composed of uncontrolled cell growth in the pulmonary extremities of the body (Crosta. 2009). When left untreated, the abnormal lung tissue eventually develops into life-threatening tumors (Crosta, 2009). Lung cancer is a disease that is particularly caused by smoking, nonetheless there are cases where it is simply developed naturally. The disease can severely harm the health of an individual over the course of years. In addition, researchers have determined that lung cancer is the leading cause of cancer deaths among both men and women (Mayo Clinic Staff, 2014). As of today, about 210,828 people in the United States have been diagnosed with lung cancer (CDC, 2015). In 2012, about

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:

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.

1. Medical terminology definition – cancer of a highly malignant form that affects the lungs.

Although cancer of the lung is the number one cause of death by cancer, it is the least funded out of all major carcinomas. Even without including the number of smokers that die from this disease it continues to be the largest cancer killer of all. Lung cancer can be prevented to an extent in a variety of ways and different approaches, but usually isn’t well detected before it’s too late.

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.
