The causes of cancer lung
Smoking – Most lung cancer related deaths (90 percent) have been associated with smoking. Every time a person smokes a cigarette, you increase your chances of getting lung cancer. Based on the formula of physicians regarding the number of packets to the number of years smoked, someone who has a 30 pack-year history has a greater chance of developing lung cancer. For those who smoke two or three or more packs a day, statistics show that one in seven diagnosed will die from the disease. Cigarette smoking is not the only culprit for lung cancer. The cigar and pipe smoking can also lead to the disease at a lower rate. People who smoke cigars or pipes are five times more likely to get lung cancer a person who never smoked.
The are in snuff smoke has over 4,000 element compounds. Many of them are cancer causing. Two carcinogens hdrycarbons key aromatic and nitrosamines. Once a person has left the snuff use, risk of lung cancer decreases each year. The cells normal start to grow and outnumber the damaged lung cells. After 15 years of not smoking, lung processes and the threat of disease approaches that of someone who has never smoked.
Passive smoking – What is passive smoking? This is when people who are near smokers quarters breathe the smoke filled the air. Those who do not smoke have a 24 percent chance of developing lung cancer if they live with a smoker. About 3,000 deaths may be associated with passive smoking.
Asbestos fibers – mesothelioma and lung cancer through asbestos exposure is high. People working in fields related to asbestos and smoke dramatically increase your chances of getting lung cancer connected disease. When compared with their counterparts Non-smokers, are at risk 50 to 90 percent higher lung cancer or lung disease related.
Radon Gas – Radon gas has been documented to be the next leading cause of lung cancer deaths, killing anywhere from 15,000 to 22,000 people in the United States each year. As exposure to asbestos, exposure to radon increases the risk of lung cancer. The gas is able to travel through the soil.

Apparently, a gene may increase the vulnerability of smokers get lung cancer.
Lung Diseases – When a smoker or non smoker has other lung diseases such as COPD (chronic obstructive pulmonary disease), which have a higher risk of developing the disease even if quit smoking and all the effects have worn.
History of pulmonary disease – People with a history of lung cancer are at increased risk of developing a second time. People who have survived a non-small cell lung cancers have a risk one fifty-nine percent, to contract the disease a second time while those who have beaten the lung cancers are small cell six per cent increase each year.
Air Pollution — The chances of contracting lung cancer from air pollution occur in people who breathe polluted air every day. Contamination of automobiles, power plants and industrialized areas increases the risks. However, represent only one percent of deaths related to cancer lung. Experts have suggested that everyday exposure to heavily polluted air can be compared with passive smoking.
