Factors That Aggravate the Risk of Lung CancerBY: Ritu Choudhary | Category: Lung Cancer | Submitted: 2010-10-23 20:44:39
In general, the risk of developing cancer increases for a person who smokes and is exposed to one of the risk factors below. Therefore in all cases it is strongly advised to stop smoking.
Exposure to radon: Radon is a colorless, odorless radioactive gas that occurs naturally in the environment. Radon is released into the air during the natural breakdown of uranium in soil and stone. It is considered as the leading cause of lung cancer and classified as carcinogenic agent. Radon can be present in homes, particularly in certain regions rich in granite, uranium or volcanic. 31 departments were identified and are under special surveillance, which requires the prefects to measurement of radon levels in some public places inform local people about the risks of radon exposure and encourage control in private buildings.
Cannabis: It is difficult to establish a link between lung cancer and cannabis as the collection of information on illegal drugs suffers from several biases. Moreover, many cannabis smokers also consume tobacco, it is difficult to know what the exact involvement of one or other of these substances. Smoking cannabis is for the time, considered a risk factor for lung cancer probable. However, we know that cannabis contains more tar than cigarettes, contains many carcinogens and if deeply inhaled into the lungs it keeps for a long time.
Exposure to asbestos: Various studies have shown that exposure to asbestos fibers increases the risk of lung cancer. People who are exposed to asbestos and smoke which moreover, are more likely to be suffering from lung cancer due to the combined effect of these two products. The risk of lung cancer is a 50 to 90 times higher than in the general population.
The radiation in a medical setting: The risk of lung cancer increased in people who have already received radiation therapy to the thorax. This may be the case for people who have been treated with radiation therapy for Hodgkin's disease or breast cancer. This risk increases in people who smoke.
Personal and family history: People with or who have been suffering from a respiratory disease is more likely to develop lung cancer like chronic obstructive pulmonary disease or COPD a phenomenon caused by progressive obstruction of the airways, it is mostly irreversible. COPD includes several diseases. The most common are chronic bronchitis and emphysema.
Beryllium disease: lung inflammation generated by the inhalation of dust or fumes containing beryllium, tuberculosis infection due to pulmonary tuberculosis bacillus. People who have been suffering from lung cancer are more likely to develop a second lung cancer than the general population. Over 80% of smokers do not develop lung cancer in part because they develop other diseases related to tobacco, researchers have hypothesized that there is a genetically transmitted individual susceptibility that gives some people the ability to metabolize more than other constituents carcinogens contained in cigarette smoke. Studies are being conducted to try to identify these sensitivities.
Age: Ageing promotes the development of cancer. The body, over the years, repairs less the changes undergone by the cells. The average age of onset of lung cancer is 64 years for women and 65 years in humans, but more and more lung cancers occur in people under 50 years, and even less than 40 years, due to heavy smoking started in adolescence.
Air Pollution: It appears that air pollution is a factor that promotes lung cancer. This effect of air pollution on the risk of lung cancer is an important issue because tens of millions of people are exposed. This pollution is caused by gases such as sulfur dioxide (SO2), nitrogen dioxide (NO2), ozone (O3), and various emitted particles, and diesel fumes.
Food: Today, the increased risk of lung cancer by consuming supplements beta-carotene, pigments considered an antioxidant, present especially in apricots, carrots, tomatoes, broccoli in people who have ever smoked and among smokers is considered convincing.
