Primary lung cancer can start in the airways that branch off the trachea to supply the lungs (the bronchi) or in the small air sacs of the lung (the alveoli)” (Hong, Tsao 2008).Instead, if cancer originated elsewhere and metastasized to the lungs, it is called “secondary”. These two types of cancer are taken as different forms of cancer from diagnostic and treatment perspectives
Lung cancer is generally classified into two main types based on the outlook of cancer under a microscope: Non- small cell lung cancer and small cell lung cancer. Non – small cell lung cancer is the type found in the majority of cases diagnosed, whereas the small cell lung
Cancer with lesser cases. “Since lung cancer tends to spread or metastasize very early after it forms, it is a very life-threatening cancer and one of the most difficult cancers to treat”(Stoppler).
The main cause of lung cancer can be related to smoking and inhale carcinogens in tobacco smoke. “Air pollution, particularly smoke from fossils, appears to increase the risk of lung cancer but its effect is small compared with that of cigarette smoking”(Williams 20). Several studies have shown that lifetime exposure to smoking can lead to the development of lung cancer. The studies have also shown that radon is the primary cause of lung cancer among non – smokers.Overall it can be said that radon is the second leading cause of lung cancer. Radon is tasteless, odorless and invisible gas produced by the decay of naturally occurring uranium water and soil.
has been the increase in the number of people smoking the cigarette. “Lung cancer may be causally related to cigarette smoking in 90% of cases in men and 79% of cases in women.”(Haustein, Groneberg 88). Another element which causes cancer is exposure to radiation in job areas or through repeated submission to chest x-rays. Even the inhaling of carcinogens like asbestos in the construction sites can lead to .lung cancer. Some industrial substances like arsenic, coal products, and nickel chromate can also cause lung cancer. .
