Cause of Lung Carcinoma
Some of the causes of carcinoma of :
* Snuff. It is the main cause. Snuff smoke, with its high concentration of carcinogens, goes straight into the air and is inhaled by both smokers as nonsmokers. Quitting smoking also significantly reduces the risk of contracting other diseases related to snuff, such as heart disease, emphysema and chronic bronchitis.
* Effects of radon. Radon is a radioactive gas that is found in rocks and soil of the earth, formed by the natural decay of radium. Being invisible and odorless, the only way to determine if one is exposed to the gas is to measure their levels. In addition, exposure to radon combined with smoking significantly increases the risk of lung cancer. Therefore, for smokers, exposure to radon is an even greater risk.
* Exposure to carcinogens. Asbestos is perhaps the best known of industrial chemicals linked to lung cancer, but there are many others: uranium, arsenic, certain petroleum products, etc.
* Readiness genética.Se know that cancer can be caused by mutations (changes) of DNA, which activate oncogene or inactivate a tumor suppressor gene. Some people inherit DNA mutations from their parents, which greatly increases the risk of developing cancer.
* Agents that cause cancer in people at risk trabajo.Entre are miners who inhaled radioactive minerals such as uranium, and workers exposed to chemicals such as arsenic, vinyl chloride, nickel chromates, products derived from coal, mustard gas and chloromethyl ethers.
* Marijuana. Marijuana cigarettes contain more tar than the snuff. Also, the smoke is inhaled deeply and held in the lungs for a long time. In addition, smoked marijuana cigarettes until the end where tar content is higher.
* Inflammation recurrente.La tuberculosis and some types of pneumonia often leave scars in the lung. These scars increase the risk that the person develops lung cancer called adenocarcinoma.
* Powder talco.Algunos studies conducted in miners and millers of talc suggest that they have a higher risk of developing the disease due to exposure to the same industrial grade talc. This dust, in its natural form may contain asbestos.
* Other types of exposure to mineralesLas people with silicosis and berylliosis (lung disease caused by breathing in certain minerals) also have an increased risk of lung cancer.
* Excess or deficiency of vitamin A. People who do not receive enough vitamin A are at increased risk of lung cancer. Moreover, taking too much vitamin A may also increase the risk of developing lung cancer.
* Pollution aire.En some cities, air pollution may slightly increase the risk of lung cancer. This risk is much lower than that caused by smoking.
