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.
Cellular / Molecular Basis: Lung cancer has two types; small cell and non small cell. The two types can be identified by their appearance when looked at with a microscope. It usually affects the cells that are lined along air passages in the lungs.
Causes: The foremost reason for lung cancer is cigarette smoking which causes around 90% of all deaths caused by lung cancer in the world. However, smoking is not the only way to get it. The second most frequent cause of lung cancer is exposure to radon gas, which is created by the decay of uranium. Exposure to asbestos can also result in lung cancer and various other lung diseases.
Signs and Symptoms: There is a range of symptoms for lung cancer, which are coughing frequently or coughing up blood, having difficulty swallowing, losing weight, a feeling of weakness or severe fatigue, pain felt within the ribcage, a swollen neck and face, shortness of breath, a croaky or gruff voice, pneumonia/ bronchitis and seizures or headaches. It can cause many complications, because the cancer could impede the patients airflow, therefore making it more difficult to breathe. Secretion could even build up behind the cancer, potentially prompting pneumonia. The cancer can also have an abundant supply of blood, and if broken, the cancer could bleed into the patients airway.
Detection: If lung cancer is suspected, CT scans and x-rays will take place to determine if the person has lung cancer. A healthy lung in an x-ray will be consistently dark, while a lung with lung ...

Two types of lung cancer, which grow and spread differently, but are the small cell lung cancers (SCLC) and non-small cell lung cancers (NSCLC). The stage of lung cancer depends on how much the cancer has spread in the body. Treatment of lung cancer can involve a combination of surgery, radiation therapy and chemotherapy ( chemotherapy is a treatment for the cancers).

According to “Medical News Today” cancer is a disease that is caused by an over growth of anomalous cells on one or more lungs. Cells often go up the air pipes which can cause difficulty to breath. Due to the over production of cells the tissue cells often begin to over produce; which results in tumors. There are two types of tumors: malignant and benign. Malignant tumors are the more dangerous of the two due to its invasive nature; which makes it cancerous. While benign is not invasive in other words non-cancerous. This is why cancer spreads to multiple areas and can be sometimes very difficult to fight. Cancer cells are abnormal not only because of their evasive nature, but also because of its irregular life cycle. Rather than expire like a regular cell, they continuously grow and duplicate which causes the disease to spread. This makes cell abnormal in shape and other qualities; known as a sickle cell. Due to the large growth and reproduction rate of the cells this makes the spreading of the cancer more rapid. Each cancer has specific symptom, for lung cancer the sympto...
Lung cancer is the uncontrolled growth of many cells that appears in one lung or even both. This type of cancer generally lines the air passages in the lungs. These uncontrolled cells grow, not becoming cell tissue, but into tumors (Crosta). Tumors form because the abnormal cells in the lungs are not the right lung cells. They are mutated and cannot be killed like normal. Once the known tumors become oversized, they take over and cause the lung or lungs not to do their jobs (Crosta). There is primary Lung Cancer and secondary. Primary lung cancer is treated differently than secondary because, primary starts in the lungs, while secondary starts somewhere else in the body, making its way to the lungs. Lung cancer is grouped in two categories ' which are non-small cell and small cell (Marks). There are four different types of cancer.
When you think of lung cancer, you think of smoking, it is the most common cause of cancer but there are many other causes that people don’t think about. You don’t have to be a smoker to develop lung cancer, secondhand smoke, radon, diesel exhaust, air pollution, and some gene changes cause lung cancer as well. The genes that help a cell grow, divide, or stay alive are called oncogenes. The genes that slow down cell division, or cause calls to die when they are supposed to, are called tumor suppressor genes. Cancer can be caused when these oncogenes turn on, or even when these tumor suppressor genes decide to turn off. Most of the genes that cause lung cancer are developed through your life; inherited genes rarely play a huge factor in lung cancer.
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.
Over 140,000 Americans die each year from lung cancer. One of the biggest causes of Lung cancer is smoking there is more than 50 different chemicals that can cause cancer in a cigarette. Second Hand smoking can also cause lung cancer if you’re exposed to secondhand smoke. The body system that lung cancer affects is the respiratory system. In all types of cancer some of the body cells begin to divide without stopping and can spread into surrounding tissue which can is the structure and function. But then the respiratory system starts to malfunction and cause problems in the body.
Cancer of the lung was nearly nonexistent in the early 1900’s. By the middle of the 20th century an epidemic became apparent throughout the United States and the rest of the world. It is primarily correlated with the widespread abundance of cigarette smoking in the world. The tobacco industry has multiplied its production immediately prior to World War I. There was a typical 20 to 30 year lagging period between the initiation of cigarette smoking and the actual tumor formation in the lungs. Lung cancer is the cancer that originates in the tissues of the lungs. It occurs when cells in the lung start to grow rapidly in an uncontrolled manner. Lung cancer can start anywhere in the lungs and affect any part of the respiratory system. Most of all lung cancer cases start in the lining of the bronchi (health-cares.net, 2005). It is the leading cause of all cancer deaths in the world. During this time the tobacco companies would continue to say that cigarette smoking was not addictive and did not cause any type of cancer. Even with all evidence in the world today about tobacco causing cancer, Tobacco companies still remain the most profitable business in the world. Lung cancer is very common in both women and men. Women account for about 40 percent of the lung cancer cases in the world. Women who smoke are more than twice as likely to develop lung cancer as those of men who smoke (Tavor, 2005).
Some of the main risk factors for this disease are smoking, which is the most substantial risk. It causes an estimated eighty to eighty-five percent of all lung
Cancer is a type of disease that has many variations. it is an extremely broad disease, consisting of over 200 different types. It affects millions of people around the world each year. The disease occurs because of an irregular cell growth in the body. The cells uncontrollably divide and grow through the process of mitosis. This creates either benign, or malignant tumors. Benign tumors are not dangerous, but malignant tumors are dangerous and are given the term ‘cancerous’. The malignant tumors can invade other parts of the body by traveling through either the bloodstream, or the lymphatic system. It is a very dangerous disease, it is not contagious, and it can be cured if it is diagnosed and treated early. Many cancers have a different mortality rate, but not all of the different types of cancers have a high mortality rate.
Lung cancer forms from abnormal growth of the cells. Since cancer comes from the cells, cancer stars in the lining of your lungs bronchi and also some parts of your bronchioles and alveoli. “Cancers
Currently, the United States of America contain thousands of people who are battling with diseases every day. On a yearly basis, a family member does the unthinkable by putting a member of their family to rest. One disease that kills numerous people each year is lung cancer. To a majority of individuals, the thought of lung cancer is devastating while to others it causes confusion and a lack of understanding. Why? What is lung cancer? What causes lung cancer? These are common questions one faces after receiving a lung cancer prognosis. Luckily, there are organizations whose sole purpose is to decipher the disease, work on treatment, and conceivably one day a cure. Lung cancer claims the lives of countless people each year and to

Lung cancer is the most common cancer in the world. There are many ways to attract lung cancer. Many people think that the only way to get cancer is by being a smoker but believe it or not you can get cancer without ever even smoking a cigarette. There also are different forms of lung cancer some are life threatening and others aren’t. My goal is for you to know everything about and or dealing with Lung Cancer by the end of this paper. Throughout this paper I will elaborate on those topics and I will also talk about some of the symptoms, and ways to prevent attracting it, cures and a few more topics.
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 ...
