The longer you smoke, the greater is your risk of
developing lung cancer. The number of cigarettes smoked per day also increases
the risk. The risk decreases considerably if the proportion of cigarettes
smoked or the smoke exposition decreases. Cigar and pipe smokers have a
slightly smaller risk than cigarette smokers, but in all cases the risk of
anyone who smokes passively or actively is much greater than the risk of a
person who does not.
The problem with cigarettes is not only related with lung
cancer, also can cause another type, as esophageal or tracheal cancer, and your
respiratory system could be strongly affected.
Some studies indicate that even the risk is greater in people who smoke
cigarettes with flavors like menthol, because menthol contributes to inhale
smoke at higher rates
WHO ARE MAINLY AFFECTED?
Undoubtedly lung cancer is one of the most aggressive
in the world and is the main cause of cancer deaths in men and women; also it
has a worldwide high incidence and a high mortality rate. Usually when the lung
cancer is detected is too late to give an effective treatment because it is
already at advanced levels and very little can be done.
LUNG CANCER SYMPTOMS:
Initial symptoms are very unspecific, such as dry
cough or hoarseness, which are very common in all smokers with and without
cancer, this is overlooked and is not given due attention. And when symptoms
worsen or become more serious people decide to go to the doctor, but it is too
late, because the stage of the disease could be advanced. The longer you wait,
the greater is your probability to die of cancer.
SMOKING IS THE COMMONEST CAUSE:
Indisputably, exposure to smoke is the most
important cause of lung cancer, although other substances, such as radon and
asbestos, are other possible causes. But these substances are only common in
people whose activities are related to mining, so this cause is rather oddly.
RADON A UNCOMMON CAUSE:
In the case of radon, which is a colorless, odorless
and radioactive gas produced by the decay of uranium in soil and rocks
throughout the world, and is the second leading cause of lung cancer and the
leading cause among non-smokers (although there is a controversial opinion
between radon exposure and passive cigarette smoke exposure).
LUNG CANCER CAUSE AMONG INDUSTRIAL WORKER
Meanwhile, asbestos is a common substance refers to a set of
six naturally occurring fibrous minerals: chrysotile, crocidolite, amosite,
anthophyllite, tremolite, and actinolite. Asbestos can be separated into
thin and durable threads, used widely in many industries, as building and
construction industries, shipbuilding and automotive industries. Also, asbestos
has been used in ceiling and floor tiles; paints, coatings, and adhesives; and
plastics. The most important thing, related to asbestos, is how the combination
of smoke and asbestos exposure is particularly hazardous.
Smokers who are also exposed to asbestos have a risk
of developing lung cancer which is greater than the individual risks of
asbestos exposure and smoking combined
The risk increases in jobs where one inhales strong
odors like toxic vapors chemicals
or diesel combustion.
ENVIRONMENTAL POLLUTION
Environmental pollution in cities and residential
areas, especially those near highways, increases the risk of developing lung
cancer. The risk is much lower than smoking; however environmental
contamination is a real risk.
In all cases of cancer,
the risk is greater if you have previously received radiation therapy to treat
cancer or you have had cancer before or a family history, in other words, if you have or had family members (related by
blood) who had cancer.
