% of readers think this story is Fact. Add your two cents.
Lung cancer is one of the leading causes of death in the world. Lung cancer is often associated with smoking, but not always the habit of smoking and lung cancer go hand in hand. Lung cancer early stage shows symptoms of coughing, wheezing, shortness of breath, and bloody mucus so often noticeably under-diagnose as TUBERCULOSIS pulmonary diseases/soap opera. Lung cancer treatment include surgery, chemotherapy, and/or radiation.
In Indonesia, lung cancer is the main cause of death into men and more than 70% of new lung cancer cases undiagnosed at an advanced stage.
Risk factors for lung cancer is something that increases the opportunity for anyone affected by cancer. Have more than one risk factor can make a person more likely to experience lung cancer. But that does not mean if you have any of these risk factors is sure you’ll experience lung cancer. And keep in mind that a lot of people who experienced lung cancer also have no risk factors are mentioned as follows.
About 85 of the 100 people with lung cancer related to smoking.
The risk of developing lung cancer that increases associated with:
The longer the duration of smoking.
A growing number of cigarettes consumed per day.
Quitting smoking lowers your risk for developing cancer, and the risk continues to fall as long as you don’t smoke. Even reducing the number of cigarettes can reduce your risk (but the risk will be greatly reduced if stopped completely).
If you live with a smoker, you have a higher risk for lung cancer compared to people who live in the neighborhood who don’t smoke. This is where you become passive smokers.
Other Risks
Exposure to some substances can increase the risk for lung cancer, include:
Smoking one marijuana cigarette can affect lungs is equivalent to smoking one pack of cigarettes.
Certain chemicals, including arsenic and asbestos.
Radiation exposure in the workplace, health tests with radiation exposure, or from the environment (such as radioactive dust).
Radon Gas. These include the exposure of your home or workplace.
Air pollution. Live where the air is very polluted, can increase the risk for developing cancer of the lungs.
Some changes to the gene (mutation) may increase the risk of developing lung cancer. Changes in this gene occur largely because of someone’s age increased.

What causes lung cancer?

The incidence of lung cancer is highly correlated with smoking, with about 90% of lung cancer arising as a result of tobacco use. The risk of lung cancer increases with the number of cigarettes smoked over time; doctors refer to this risk in terms of smoking history (the number of cigarette packs smoked per day multiplied by the number of years smoking). And people with a history of smoking 3 packs per day, is considered to have the greatest risk for developing cancer of the lungs. Among those who smoked two or more packs per day, one of the seven people will die of lung cancer. But despite the risk will be even higher than the amount and duration of smoking, no word is safe from exposure to tobacco smoke.
Pipe and cigar smoking can also cause lung cancer, although the risk is not as high as with smoking. While someone who smokes a pack of cigarettes a day had a risk of developing cancer of the lung only has 25 times higher than not smokers, pipes and cigars for smoking has the risk of lung cancer that is about 5 times that of who is not a smoker.
Tobacco smoke contains more than 4,000 of chemical compounds, many of which have been proven to be carcinogenic, or cancer-causing. Two major carcinogen in tobacco smoke are chemicals known as polycyclic aromatic hydrocarbons and nitrosamines. Risk of lung cancer decreases every year after smoking cessation because normal cells grow and replace damaged cells in the lungs. In former smokers, the risk of developing lung cancer began to approach such as that is not a smoker around 15 years after quitting.
Passive Smokers
Passive smoking, or inhaling tobacco smoke from other smokers, living with friends or work, is also a risk factor for the development of lung cancer. Research has shown that non-smokers who live with smokers have increased 24% in the risk of lung cancer compared to smokers rather than others. Estimated deaths from lung cancer occurred as much as 3,000 inhabitants in the U.S. caused by passive smoking.
