The Cause And Environmental Causes Of Lung Cancer

     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.

A common form of cancer that is very popular today is lung cancer. Lung cancer is a very dangerous form that can cause problems in simple body functions. These simple body functions are short breath and general fatigue. Lung cancer is commonly formed from smokers that has been exposed to that activity for numerous years. Lung cancer can also be spread by being exposed to asbestos or other pollutants. This form of cancer has many risk factors to it. These risk factors are high levels of air pollution, arsenic drinking water, and radon gas. Radon gas is a gas that is highly radioactive and is very sensitive to the body. Once radon is exposed to the body, it has a very high respiration rate which initially divide its radioactive cells- causing more significant damage to the body.

Statistics report that radon is the number one cause of lung cancer for non-smokers in the US and the second leading cause of lung cancer overall.

The U.S. Ecological Assurance Organization (US EPA) and the Top health spokesperson's Office have evaluated that upwards of 20,000 lung tumor passings are brought in every year by radon. Radon is the second driving reason for lung tumor. Radon-impelled lung malignancy costs the Unified States over $2 billion dollars for every year in both immediate and circuitous social insurance costs. In view of National Tumor Foundation measurements of 14,400 yearly radon lung growth passings - Oster, Colditz and Kelley, 1984.

Lung cancer is the leading cause of death by cancer for both men and women in the United States (Stöppler, n.d., p. 3). As the name suggests, lung cancer is a cancer of the lung, where an abnormal growth of cells form a mass (tumor) on the lung (Stöppler, n.d., p. 2). This happens when a cell with aberrant DNA divides to create two new cells with the malformed DNA. This process occurs for each and every cell and because healthy lung tissue is not being made, a tumor develops. This tumor can be harmless, but in most cases, it is malignant and can have the potential to metastasize (“Lung Cancer 101,” n.d., p. 1). Lung cancer was not always the superior malady; in fact, only 1% of all cancers seen by the Institute of Pathology of the University of Dresden in 1878 were malignant lung cancers (Witschi, 2001). It appears

Cancer can be one of the hardest battles that one must face, whether that battle is lost or won, it changes the lives of everyone involved. Lung cancer is one of the most diagnosed cancers and it affects the lining of the lungs and the ability to breathe. Lung cancer is the number one killer of men and women than any other cancer worldwide. This cancer is mostly found in smokers and this is why professionals are targeting this population for testing for diagnosing early and possibly saving a life (www.ncb.nlm.nih.gov). Lung cancer refers to the malignancies that originate in the airways or pulmonary parenchyma.

Large amounts of non-small-cell lung cancer cases are caused by smoking, and many others are caused by exposure to secondhand smoke. Smoking is the most common factor that led to non-small-lung cell cancer.Smokers face other risk factors such as radon and asbestos. But the fact is that not everyone smokes with lung cancer. Lung cancer in nonsmokers may be due to exposure to radon, get the chemicals gas from one who smoking, air pollution or many other reason such as the bad chemicals, or working at the workplaces exposure to asbestos can also cause non-small-cell lung cancer. Non-smokers often have cancer at a younger age than smokers.

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 is one of the most common types of cancers in the world. There are three main types of lung cancer, non-small cell lung cancer, small cell lung cancer, and lung carcinoid tumor. Just like any other cancer, lung cancer is dangerous, and a life threatening problem. Many studies and researches have been presented to find a cure, but an exact cure has yet to be found. There are however multiple causes, ways to diagnose, and treatments for lung cancer.

According to the American Cancer Society, lung cancer is the most common type of cancer in the world and has a mortality rate higher than colon, prostate, ovarian, and breast cancers combined.1 There are 3 types of lung cancer including non-small cell lung cancer, small-cell lung cancer, and lung carcinoid tumor. Approximately 85% of lung cancer cases are non-small cell, which include subtypes of squamous cell carcinoma, adenocarcinoma, and large cell carcinoma.2 Although less common, making up 10-15% of lung cancers, small-cell lung cancer is known for its rapid growth and spread.2 The types of lung cancer vary greatly in the prognosis and management of disease, as rate of growth, risk of metastasis, rate of recurrence, and treatment options are different with each.2 Physical therapy serves an integral role in the management of patients with lung cancer by providing interventions to optimize pulmonary and cardiovascular function.

The U.S. Natural Protection Agency (US EPA) and the Surgeon General's Office have evaluated that upwards of 20,000 lung growth deaths are brought on every year by radon. Radon is the second driving reason for lung disease. Radon-incited lung malignancy costs the United States over $2 billion dollars for every year in both immediate and backhanded human services costs. (In light of National Cancer Institute insights of 14,400 yearly radon lung disease deaths - Oster, Colditz and Kelley, 1984)(Radon facts)

Lung cancers are broadly categorized as non–small cell (NSCLC) and small cell (SCLC) lung cancers, accounting for around 85 and 15% of all lung cancers, respectively. The most common histologic subtypes of NSCLC are adenocarcinoma (50%), squamous cell carcinoma (35%), and large cell lung cancer (15%). Subtypes of adenocarcinoma include broncho-alveolar, acinar, and papillary; subtypes of large cell lung cancer include giant cell and clear cell carcinomas, both of which carry poor prognosis. Adenocarcinomas are the histologic type associated with smoking.

The second cause is environmental issues that play a key factor in causing cancer. Air pollution and release of industrial waste products is a major cause for cancer. The air pollution is caused to adding of contaminated gases or air to the environmentthis includes Nitrogen di- oxide, carbon di-oxide, sulphur di-oxide etc. PAH- Polycyclic aromatic hydrocarbons , formed by highly bonded aromatic compounds is danger aromatic gases results in lung cancer . the person who taking this contaminated through their breath for prolonged time got suffered by lung cancer. Lung- cancer is very risky and complicated one. The chemical compounds that are releasing from industries also responsible for bowel

Environmental factors that commonly cause lung cancer is asbestos fibers and other similar materials. Asbestos is a heat-resistant fibrous silicate mineral that can be woven into fabrics, and is used in fire-resistant and insulating materials (MedicineNet). Recently, in study has been limited or even banned due to the cancerous causing agents in the product. This material causing mesothelioma which is a specific cancer of the lungs, which is greatly increased when someone is a smoker and they are introduced into asbestos. Even non-smoking asbestos workers have a higher risk of developing lung cancer; as for the smoking asbestos workers, their chances to get cancer are up compared to nonsmokers. This causing the lung to stop working correctly

Cigarette smoking is the major cause, although some people diagnosed with lung cancer have never smoked. Occupational exposures to asbestos, radon, hydrocarbons and metals (e.g. chromium, nickel) are also associated with lung cancer. The major way to prevent lung cancer is by not smoking or quitting smoking. However about 37% of Australians
