Cancer has caused a total of 7.6 million deaths annually, or about 13% of deaths worldwide. Lung cancer being the most common type, accounts for 1.37 million of those deaths. But what are the leading factors that cause this type of cancer and what can be done to prevent the increasing number of deaths? Lung Cancer can be defined as an uncontrolled growth of abnormal cells in either one or both lungs of an organism. These abnormal cells divide and multiply to create unhealthy tissue or tumors inside of the lungs. These tumors interfere with the lungs ability to deliver oxygen to the body. Though lung cancer can originate inside of the lungs, it can also originate in other parts of the body. When the cancer begins inside of the lungs it’s called Primary Lung Cancer, when the cancer begins in other parts of the body and spreads to the lungs this is called Secondary Lung Cancer. These two different origins of the cancer cause the treatments and symptoms to very in similarity, though Primary Lung Cancer is the main cause of lung cancer deaths worldwide. Lung Cancer can be divided additionally into types and stages of development to determine the severity of the disease, there are several types of lung cancer and four stages of development. The two major types of lung cancer include Non-Small Cell Lung Cancer (NSCLC) and Small Cell Lung Cancer (SCLC). According to the American Cancer Association, 85% of lung cancers are Non-Small Cell Lung Cancer, while Small Cell Lung Cancer occurs less frequently with the remaining 15% of lung cancers. However, there are several subtypes of NSCLC. The most common include: Squamous cell (epidermoid) carcinoma, Adenocarcinoma, and Large cell carcinoma. The subtypes of NSCLC ... ... middle of paper ... ...cer Society. N.p., n.d. Web. 25 Apr. 2014. "Lung Cancer." Basics of Lung Cancer. Mayo Clinic, n.d. Web. 27 Apr. 2014.

However, other forms of treatment may also depend much on the type of lung cancer that is being treated and it's staging. Be it the more rapid growing Small Cell Lung Cancer (SCLC) that makes up for between 10% - 15% of all diagnosed cases, or the more common and slower growing Non Small Cell Lung Cancer (NSCLC).
Smoking is the most preventable cause of death in our society. During 1995, approximately 2.1 million people in developed countries died as a result of smoking. One tobacco use is responsible for nearly one in five deaths in the United States. Lung Cancer mortality are about 23 times higher for current male smokers and 13 times higher for current female smokers compared to a lifelong never-smoker.
There are more than a million people suffer from cancer in the United States every day. Lung cancer is not the only type of cancer but it affects many people and families every day. Lung cancer makes the lives of its patients and the families. Lung cancer is one of the deadliest types of cancer and also one of the most common. Hundreds of thousands of people get diagnosed with lung cancer every year in just the United States. Also close to just as many people die from lung cancer in the US every year. I am going to talk about lung cancer and what it is, how to lower your risk of getting it, statistics of it, and the research and treatment of it.
Both small cell and non-small cell lung cancer affect different types of cells in the lung and spread in different ways. Small cell lung cancer is limited to a section of the chest known as the hemithorax and regional lymph nodes (World Book, “Lung Cancer';). Small cell lung cancer usually exists early and spreads out abruptly (Virtual Hospital, 3/23/99). Non-small cell lung cancer is first confined to the lung, then spreads throughout the chest (MSKCC, “Lung Cancer';). Small cell lung cancer spreads quickly (World Book, “Lung Cancer';).
The working of the lungs is vital to the human physical structure. They provide the body with oxygen to keep the cells happy and help to maintain homeostasis. There are many carcinogens that cause cancer leading to the lungs not to doing their job. Sometimes the cancer spreads and causes metastases. The patient’s medical diagnosis is malignant neoplasm of the bronchus and lung brain metastases.
Over the years, the partnership between health ministers and health groups has produced some very substantial gains on the subject of tobacco use. Smoking bans that were thought of as radical 20 years ago are now commonplace. Public awareness of smoking risks has never been higher. And our new Tobacco Act sets a world standard for anti-tobacco legislation.
Lung cancer is arguably the most devastating of all cancers, leading to more annual deaths than breast, prostate, and colon cancers combined (Crosta). 228,000 new cases are found every year (Marks) and there are approximately 1,370,000 deaths per year. Cancer in general accounts for 7.6 million deaths all around the globe. Cancer alone stands for thirteen percent of global deaths (Crosta). The percentage for the survival rate of lung cancer is a devastating sixteen percent (Marks)! More females are diagnosed with this cancer over men, but does not mean men cannot get this cancer as well. Actually, my uncle was diagnosed with lung cancer this past Summer. Shockingly, a couple of months later, my cousin, who I call my grandmother was diagnosed

Non-small-cell lung cancer is more common than small-cell lung cancer. It makes up about 80 percent of all diagnosed lung cancers. It is actually four different kinds of lung cancers that grow and respond to treatment in about the same way. These four types of non-small-cell lung cancer are termed squamous cell, adencarcinoma, large cell, and mixed cell. Two other related cancers that are also included in the non-small-cell lung cancers group are carcinoid and mesothelioma. Non-small-cell lung cancer grows more slowly than small-cell lung cancer. Non-small-cell lung cancer tends to grow first in the area where it started then invades the surrounding lung tissue and ribs. It eventually spreads to other areas of the body, mainly bones, brain, and liver.
The leading cause of death in America is lung cancer. Lung cancer is ranked top 10 fatal cancers in the United States. There are many types of ways to get lung cancer. There is radon gas it occurs outdoors naturally. Then there is second hand smoke that comes from other people smoking. People are even getting lung cancer from cancer causing agents, this happens from carcinogens. You can also get it from air pollution indoors and outdoors. Also there are gene-mutations that form cancer causing cells. Then there is the one everyone blamed lung cancer is smoking.
Cancer Cancer is a disease in which cells grow out of control and invade, erode, and destroy normal tissue. Damaged genes cause this development of cancer. These damaged genes are often a factor caused by such things such as the environment, and can be influenced by inherited factors. As the very early damaged cells divide they can evolve into a malignant cell population, and lose the control mechanism that govern normal cell division. These malignant cells can then go on to form solid tumours that start to destroy normal tissue.
Amongst the different types of fatal diseases, which humanity still has not been able to treat, cancer stands as one of the greatest feared illnesses. Unlike malaria, AIDS or other diseases that are contagious and easily transmittable in underdeveloped and low income countries, Cancer affects people all around the world, including equally rich and poor countries. Among the different forms of cancer, lung cancer remains the most common. The environment in which the public lives in plays a huge role in the development of this cancer. Cancer develops when cells in the body are mutated, and thus causing uncontrollable and rapid growth. Lung cancer is the uncontrollable development of atypical cells that form in either both or one lung. Lung cancer
This represents 4.0% of all male 1.8% of female hospitalisations respectively. The epidemiologic evidence and the corresponding biological understanding of respiratory cancer have supported the conclusion that smoking causes lung cancer. It is well documented that cigarette smoke: · is the major cause of lung cancer (primary carcinoma of the lung). · is a cause of heart disease, chronic lung disease, and oesophageal cancer.
