Lung Cancer : Causes, Symptoms, And Treatment

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.

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.

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

The leading cause of cancer death for both men and women in the United States and worldwide is lung cancer. Lung cancer is responsible for thirty percent of cancer deaths in the United States. The deaths caused by breast cancer, colon cancer and prostate cancer combined do not add up to the deaths that lung cancer causes. In 2007, 158,683 people, 88,243 men and 70,354 women died from lung cancer in the United States (Eldridge, 2012). Out of the 158,683 people that died from lung cancer in 2007, 135,000 of them died of lung cancer caused by smoking cigarettes. The overall survival rate of those with lung cancer is at about fifteen percent.

Cancer is the leading cause of death in economically developed countries and the second leading cause of death in developing countries. Based on the GLOBOCAN 2008 estimates, about 12.7 million cancer cases and 7.6 million cancer deaths are estimated to have occurred in 2008. The leading cause of cancer mortality in females is breast cancer, accounting for 23% followed by lung cancer and cervical cancer accounting for 11% respectively. Furthermore, estimates show that, the leading cause of cancer mortality in males is lung cancer accounting for 17% of the total new cancer cases and 23% in total cancer deaths. [2].

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 with 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.

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.

Lungs are a major part of the respiratory system. They are responsible for filtering carbon dioxide out of the air we inhale and sending oxygen into the bloodstream to aid in breathing. When that system is tampered with, things can go wrong. Different treatment methods have different levels of success and each target certain areas of the cancer in attempt to destroy the disease. This report investigates the effects of cancer on the lungs and will look at whether or not physical activity positively affects the growth/diminishment of the cancerous cells.

Lung cancer is one of the most common types of cancer, but more importantly, it has a very low survival rate. The sad truth is that nearly all cases of lung cancer could have been prevented, simply by not smoking. Mr. Ward is a perfect example of this in the case study. Having smoked for approximately 67 years, it was only a matter of time before he developed some type of cancer, in this case lung cancer. This paper will describe how lung cancer, specifically squamous cell cancer of the right lung, affects Mr. Ward’s body, beginning with the potential and actual risk factors for lung cancer. Followed by changes that occur in the respiratory system as a result of lung cancer, and ending with the organs at risk as lung cancer spreads.

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.

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

• Lifestyle changes can be made to reduce the risk of getting lung cancer. These include quitting smoking, testing for and removing radon in the home, and protecting the lungs at

Lung cancer is a disgusting disease that many have died from. It is the largest single cause of cancer deaths in America. It causes more deaths than colon, breast and pancreatic cancer combined. People shouldn’t have to suffer from this disease. We have to prevent any more cases of lung cancer.

Lung Cancer, like any other types of cancer, is an excessive production of lung cells. Human body has a maintain system of checks and balances on cell growth thus cells divide to produce new cells as it needed. Any changes of this balance system such as smoking Cigarette, high levels of air pollution, Arsenic poisoning, Radiation therapy and etc. These causative agents will lead to uncontrolled cell division which result excessive amount of cells eventually forms a mass known as a tumor.
