Papers 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

However, there are stages in the lives of all humans when the body finds itself in a position where it is no longer able to defend itself against ailments and diseases and eventually may even lose the battle. One such disease which claims many lives every year in this manner is Cancer. So far so, there has been no cure for Cancer but some medicines and treatments are now available which can slow down and in some cases can even alter the effects of Cancer, depending on the stage at which the disease is at that moment. For this paper however we would concentrate on Lung Cancer and its effects.

|Specific Purpose: |To inform readers on the causes, effects and treatments of lung cancer. |

Specifically, lung cancer has become a major health problem worldwide. With specific reference to USA, the disease causes nearly 31% of the deaths in men and 26% if cancer deaths in women. Because of such statistics, Lung cancer has received a lot of attention in terms of research reports. Recent studies show that one in eight lung cancer patients can only live for five years after their diagnosis. These studies have reported that lung cancer would be reduced if people stopped smoking tobacco products.

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

Each year there are about one million three hundred seventy thousand deaths worldwide from lung cancer. Lung cancer is a particular type of cancer that is more deadly and common from other types of cancer. Lung cancer for most people can be avoided because cigarette smoking is the primary cause of lung cancer. Of course, there are other ways that increase the chance of lung cancer that can’t be avoided, like if it runs in the family. There are two different types of lung cancer small cell lung cancer, and non-small cell lung cancer. In order to determine what the specific type is it needs to be looked at under a microscope as the two types have different treatments. There are many symptoms that may be associated with lung cancer, not all are present in the chest, some symptoms occur in different regions of the body. Lung cancer had a variety of treatment options. The patient's doctor will decide what treatment is best for them depending on their type of cancer and what stage of cancer they have. In the novel The Longest Ride Ira Levinson, a ninety-one-year-old man had been battling lung cancer for the past few months. Sadly his cancer did not get found early enough, so his last few years turned into only a few more weeks.

What is cancer? Cancer is a disease caused by an uncontrolled division of abnormal cells in a part of the body. Cancer kills roughly seven and a half million people annually. The deadliest is lung cancer, with a whopping thirty-one percent of them dying from it. There are two types of lung cancer: non-small cell lung cancer and small cell lung cancer. The three main types of non-small cell lung cancer that are named for the type of cells in which the cancer develops: they’re squamous cell carcinoma, adenocarcinoma, and large cell carcinoma. The other lung cancer, small cell lung cancer, which sometimes is referred to as oat cell cancer, is less common than non-small cell lung cancer and grows quicker. Therefore, it’s more likely to spread to

     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.

Cancer is a disease that plagues millions of people annually (“Lung”). Lung cancer develops when healthy cells in the lungs are compromised by chemicals, pathogens, or radiation (Henderson). In the early twentieth century, before cigarette smoking and toxic man-made air pollutants became more commonplace, lung cancer was relatively rare (Henderson). It is now the leading cause of cancer deaths worldwide, resulting in an estimated 1.3 million deaths annually (“Lung”). Lung cancer is second only to breast cancer as the leading cause of death in women worldwide (“Lung”). In the United States, however, lung cancer is the leading cause of death in women (“Lung”). Lung cancer can occur at any age, but it occurs primarily between the ages of forty-five and seventy-five (“Lung”). The four leading causes of lung cancer are smoking cigarettes, exposure to radon, secondhand smoke, and asbestos exposure.

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 leads with both the number of diagnostics and deaths of cancer. Although it is typically caused by smoking, Lauren developed lung cancer because of the harmful chemicals and radiation that she was exposed to on a daily basis. She began to experience a cough that would not go away, chest pain, wheezing, shortness of breath, and even coughing up bloody phlegm. Some patients are lucky. Cancer is caught in the first or second stage, but because the symptoms are not common or regular until a later stage, it sometimes goes undetected until it is too late. Lauren was diagnosed with stage 3 because she was unable to detect any problems early on. In Jane E. Brody’s article, “Screening, and Enabling, Smokers” she interviewed Dr. Russell P. Harris, who stated, “’At best,’ he said, ‘screening might reduce lung cancer deaths by 8,000 a year. But in the year 2000 alone, smoking cessation reduced lung cancer deaths by 70,000’” (Brody 1). Cancer is not a death sentence, and one can often prevent it from developing in extremely simple ways. If it is not prevented, cancer patients go through a number of symptoms that drastically affect their life, and their loved ones’ lives. The first symptom begins with drowsiness and loss of energy.

The good news is that people who smoke can drastically decrease their risk of lung cancer by quitting. Keep

Lung cancer is considered to be the leading cause of cancer death worldwide. There are approximately about 180,000 cases that are diagnosed in America, considering that 90% dies thru lung cancer alone. Despite of its number, it is the most preventable of all the cancers. Like every cancer it spreads out fast if not taken seriously, this due the abnormal growth of cells. The abnormal cell growth often leads to the formation of tumor. This cancer is very common and very deadly. The following common symptoms of lung cancer may include excessive coughing, chest pain, shortness in breath, hoarse voice, swelling on the face and neck, unexplained loss of appetite and tiredness. It may be hard to determine, if a person has a lung cancer. The

Lung cancer takes the lives of many at a young age and the cause isn’t always clear as of how this disease was contracted. The most popular idea of what causes lung cancer since early times has been using tobacco. Tobacco contains nicotine which is a highly addictive drug that gives a temporary feeling of relaxation. When people get addicted to nicotine, it becomes incredibly difficult for the victims to stop smoking. According to Brody, Lung cancer has been shown to take the lives of more people compared to any other form of cancer and this is the case since lung cancer is associated with life style. New information regarding lung cancer has shown that about one-fourth of those victims who are diagnosed didn’t obtain it through first hand smoking. People can obtain this illness through an “unlucky” combination of genetics (Brody).

As far back as Jean can remember she’s always been attracted to Alan. Jean belonged to the poorest family in the clan and her father is the Laird’s farrier. Her mother Brenda, works in the castle’s kitchen preparing food for the royals. Her first glimpse of the castle was when she turned 16 and was employed as an extra hand to do the dishes and clean the kitchen floors. Those were also the few times she’d chance upon Alan who was 22 at that time. He’d come in sometimes dressed in his armor as he practiced jousting with his father’s men. Alan, being the first-born male in the family was the successor to the Lairdship. He was tall with blue eyes, robust physique, and blonde hair. He was always preoccupied with so many things his father would
