The Main Causes Of Lung Cancer in Smoker and Others
The main causes of lung cancer is smoking, both in active smokers and in passive smokers. But people who do not smoke or exposed to cigarette smoke also can suffer from lung cancer. Some of the causes of lung cancer will be described further below.
Active Smokers and Passive Smokers
Approximately 80-90 percent of lung cancer cases are caused by smoking habits. So active smokers become the most risky group. Cigarette smoke is inhaled, contains more than 60 toxic substances that can trigger the development of cancer. These toxic substances are known as carcinogenic. For example nicotine used in insecticides and tar used in the manufacture of road asphalt.
Initially, this damage can be repaired by the body. But the repetition and sustainability of smoking causes damage to the lung tissue continues to grow. Damage is what causes the cells to react abnormally until finally emerged cancer cells.
Currently, more than 60 million Indonesians are active smokers. This number continues to grow from year to year. Indonesia ranks third in the countries with the highest active smokers, behind China and India.
In addition to tobacco, marijuana also contains substances that can trigger cancer. Tobacco is often mixed with cannabis. Although the quantity of tobacco mixed with cannabis is less than that of cigarettes, the cannabis smokers suck deeper and longer. The effects of tobacco sucking mixed with marijuana are much worse than smoking regular tobacco cigarettes.
Passive smokers are people exposed to cigarette smoke but do not smoke directly. Although not smoking directly, passive smokers remain at risk of lung cancer. The risk of passive smokers exposed to lung cancer increases at least 20 percent compared to people who are not exposed to cigarette smoke exposure.
According to WHO data, Southeast Asia is in second position as a contributing region to the bad air pollution in the world. The risk of developing lung cancer will increase if we are exposed to air pollution exposure for example from vehicle fumes or factory smoke. About one in 100 deaths from lung cancer are caused by high levels of pollution. Inhaling exhaust fumes from vehicles and factories can have the same impact as passive smoking.
Some jobs have a likelihood of being associated with an increased risk of developing lung cancer. Employees exposed to some chemical compounds that are carcinogenic, such as asbestos, nickel, coal, silica, and arsenic have a higher risk of developing lung cancer.
Radon is part of the air we breathe. Radon is a naturally occurring radioactive gas. This gas comes from rocks and soils in very small quantities.
This radon gas can move through the soil. This gas will enter into the house through foundation cracks, pipes, drains or other open pits. This gas can be tested with simple testing tools, because radon gas is invisible and odorless. If inhaled, radon gas can damage the lungs, especially for a smoker.
