This year thousands will be affected by some form of lung cancer. Many do not know what lung cancer is and what its effects are. Also, unknown to most are the causes of this cancer. Another factor of lung cancer people do not understand is how many are victims to this disease. Lung cancer is a disease of which many people have heard of but do not understand what it is and what it does, what causes it, and how many it is affecting.
Many people may have heard of lung cancer but do not know the specifics. The cancer comes in a few forms of which are all tumors. According to U·X·L Encyclopedia of Diseases and Disorder, “Lung cancer is the uncontrolled growth of malignant cells in one or both lungs. There are two major types of lung cancer, small cell lung cancer (SCLC) and non-small cell lung cancer (NSCLC)” (pg. 670). Non-small cell lung cancer accounts for 85 percent of all forms of lung cancer. Small cell lung cancer follows with 10 to 15 percent and less than 5 percent are carcinoid tumors. Normal symptoms of

Smoking is the major cause of lung cancer, but other major causes are radon, asbestos, and air pollution. Going into the 1900’s only 134 cases of lung cancer had been recorded. This number would mostly increase due to smoking; however, due to the increasing air pollution in countries such as China, more cases would arise. For the most part, lung cancer would disappear if it was not for smoking. As Charles A. LeMaistre explains, “And yet, the most difficult type of cancer to cure is also the easiest to prevent in the first place -- 80 percent to 85 percent of all lung cancers are directly -- unequivocally -- linked to prolonged tobacco use” (para. 4). Cigarette smoking caused 150,000 new cases of lung cancer in 1986. Due to lung cancer having such common causes thousands are affected by it each year and place it at the top in the most common and deadly
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).
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.
Lung cancer dates back to 1761 when it was called disease. In 1878 only 1% of the populations were thought to have it. When the 1900s came by that number rose to 15%. There was only 374 case filed by 1912. It wasn’t until 1929 when smoking became a factor in lung cancer. Fritz Lickint was the first person to tell the public about the dangers of smoking that which went into a campaign act to tell worldwide about the dangers of smoking.
In addition to being responsible for 87% of lung cancers, smoking is also associated with cancers of the mouth, pharynx, larynx, esophagus, pancreas, uterine cervix, kidney, and bladder. Smoking accounts for at least 29% of all cancer deaths, is a major cause of heart disease, and is associated with conditions ranging from colds and gastric ulcers to chronic bronchitis, emphysema, and cerebrovascular disease. Women have a better chance in getting lung cancer then men do. This year the disease will kill 68,000 women in the United States, more than one and a half times as many as breast cancer. Even if a woman smoked for awhile and quit, her chances are much greater then a man that smoked 2 times longer then the woman did.
Initially, cancer kills many people. There are over one hundred different types of cancer, and half of them have been cured at a time. Even at that there is still no guaranteed cure. Sure you’ll have a higher chance of curing cancer if you catch it early in the making, but not everyone does. A cancer report by a leading US health organization estimates that cancer kills 7.4 million people worldwide this year. Every four out of ten patients are diagnosed with cancer, but only four out of ten people that have been diagnosed with this ugly disease catch it early. That leaves 60% of everyone with cancer a guaranteed death. So why are so many people dying from it and why hasn’t this disease been extinguished, even after fighting with it for over a hundred years? The obvious answer is because cancer is a very hard disease to cure.
Since the 1950s, more than 70,000 scientific articles have left no doubt that smoking is an extraordinarily important cause of premature mortality and disability around the world. In populations where cigarette smoking has been common for several decades, about 90% of cases of lung cancer, 15–20% of cases of other cancers, 75% of cases of chronic bronchitis and emphysema and 25% of deaths from cardiovascular diseases in those 35–69 years of age are attributable to tobacco. Studies have shown that half of all long-term smokers will die of a tobacco-related disease and, of these, half will die before the age of 65 (World bank, 1999).
As most of you know, smoking is bad for your health, but what some of you might not know is that you don’t actually have to smoke to be harmed by smoking. Lung cancer, which is the leading cause of cancer deaths in men and women, is mainly caused by cigarette smoking. Secondhand smoking causes approximately 2 percent of lung cancer deaths each year. It causes respiratory disease, Sudden Infant Death Syndrome (SIDS), middle ear disease, and asthma attacks in children.
Cancer is defined as where the abnormal cells are divided without any control and they are able to invade into tissues. At times cancer can be cured right away once it is detected through treatments that the doctor recommends, but at times cancer cannot be cured based on what stage the cancer is at. It is very important that every individual gets a physical check up to see if they are diagnosed or detected with any sort of cancer or disease. There are 100 types of cancers out there, but the type of cancer that I will be focusing on is Lung cancer. One of the controversial issues on a lung cancer is the ...
Small cell lung cancer is one of two main types of lung cancers. “Small cell and non-small cell lung cancers are treated differently” (American Cancer Society). You have a ten to fifteen percent chance of your lung cancer being small cell lung cancer. The most common lung cancer is non-small cell lung cancer, which is eighty to eighty-five percent of the type of lung cancer you have. Your left lung is smaller than your right lung because that is the side your heart is located on, which means it has to work a little harder than your right lung.
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.
Lung cancer is the number one cause of cancer-related deaths in the United States. It occurs when a malignant tumor develops within the lungs causing cell mutations. There are two main types of lung cancer: non-small cell lung cancer and small cell lung cancer. Non-small cell lung cancer is the most common type of lung cancer. According to the American Cancer Society (ACS), non-small cell lung cancer accounts for 85 percent of lung cancers whereas small cell lung cancer accounts for 10-15 percent. Non-small cell lung cancer can be categorized into three different types: adenocarcinoma, squamous cell carcinoma, and large cell carcinoma. Adenocarcinoma is the most common subtype of non-small cell lung cancer. It accounts for 30 - 35 percent of primary lung tumors. Squamous cell carcinoma occurs when abnormal lung cells multiply out of control resulting in the formation of a tumor (Harvard Health Publications). Squamous cell carcinoma is the second-most common type of non-small cell lung cancer. It
Lung cancer is one of the wide spread cancers related death in the world (1). The most widely recognized destinations of metastatic spread in lung cancer are the adrenal organs, cerebrum, bones and liver.
As mentioned earlier, there are two types of lung cancer: NSCLC and SCLC. NSCLC can be divided into three sections. First, there is epidermoid carcinoma which is usually starts in the large breathing tubes, and grows slowly. (5) There is also adenocarcinoma, which is found in the mucus glands and ...
Approximately one in two lifetime smokers will die from their habit. Half of these deaths will occur in middle age. The most common of the diseases caused by smoking is cancer, of course. Not only is it a cause of lung cancer, but cancer of the larynx, and the esophagus, and it contributes to the development of cancers of the bladder, pancreas, and kidney. Lung cancer comes from the tar in the cigarettes.
Smoking is a simple process of inhaling and exhaling the fumes of burning tobacco, but it has deadly consequences. According to the American Cancer Society, smoking is the most preventable cause of death in America today (Encarta, 2002). Until the 1940?s, smoking was considered harmless. It was at this time that epidemiologists noticed a dramatic increase in the cases of lung cancer. A study was then conducted between smokers and nonsmokers to determine if cigarettes were the cause of this increase. This study, conducted by the American Cancer Society, found increased mortality among smokers. Yet it was not until 1964 that the Surgeon General put out a report acknowledging the danger of cigarettes. The first action to curb smoking was the mandate of a warning on cigarette packages by the Federal Trade Commission (Encarta, 2002). In 1971, all cigarette advertising was banned from radio and television, and cities and states passed laws requiring nonsmoking sections in public places and workplaces (Encarta, 2002). Now in some cities smoking is being completely banned from public places and workplaces and various people are striving for more of these laws against smoking.
