The prevention of lung cancer

Nowadays scientists elaborate on determining the mechanism of oncogenesis and recommendations for preventive treatment of the lung cancer.

Scientists stated that in the context of protection and prevention against lung cancer large consumption of anticancer vegetables from the family of crucifiers (broccoli, cabbage, cauliflower, Brussels sprout) can protect against this disease which probably results from the presence of phyto-substances in the abovementioned vegetables. Especially broccoli and Brussels sprout seem to play a certain role in the prevention of lung cancer as they contain a considerable dose of magnesium which deficiency in body reduces the abilities of DNA repair. Research results indicate that low consumption of fatty acids from omega-6 family and at the same time high consumption of fatty acids from omega-3 family may help in the prevention of lung cancer. The results showed that the exhibition of lung cancer cells to eicosapentaenoic acid reduces the production of prostaglandins of arachidonic acid which may lead to the reduction in the proliferation of cancer cells.

The risk of lung cancer development is lowered when women are having regular physical activity. Eating fruits regularly protects both women and men from cancer of this type. The research showed negative correlation between the consumption of boron and the development of lung cancer in women. Preliminary results indicate that sufficient consumption of copper, zinc and iron lowers the risk lung cancer development and plays an important role in lung cancer prevention. It is considered that such situation occurs because DNA might be stabilised through these mineral ingredients.


The most important risk factor of developing lung cancer is active smoking. The prevention of  lung cancer is based on a foundation not-smoking tobacco as such. To other risk factors (5-10 % of cases becoming ill) are included: passive smoking of tobacco, exposition related to one’s profession to asbestos and certain metals, silica and ionising radiation (particularly exposition to radon). The risk of lung cancer development is growing along with age, lung cancer rarely attacks persons under 50. 75% of all cases regards persons over 63.

About 9 to 10 persons who developed lung cancer are smokers or used to smoke in the past. A person's increased risk of contracting lung cancer is associated with the amount of cigarettes smoked and  with the length of time that a person continues to smoke. About 4000 harmful substances can be found  in tobacco smoke. The risk of death due to lung cancer increases eight times if a person smokes from 1 to 14 cigarettes per day. The length of continuing smoking is even more important risk factor than the number of cigarettes smoked. If a non-smoking person is a partner of a smoker, the risk of lung cancer occurrence is by 30% greater than in case of a person remaining in a relationship with somebody who does not smoke. In such case the prevention of the lung cancer is particularly important.

The consumption of marijuana which contains many substances triggering cancer is regarded as a factor responsible for lung cancer development.

Persons exposed to the effect of asbestos die of lung cancer 7 times more often than the other part of  population. Asbestos can cause numerous morbidities in lungs or their lining. Lung cancer appears more often at miners working in uranium mines which is assigned to the effect of radon - radioactive product of uranium disintegration. The risk of lung cancer development depends on the dose of radon. It should be emphasised that smoking tobacco in such case results synergistically.

It is considered that excessive exhibition to exhaust fumes coming from diesel engines probably causes the risk increase of lung cancer development but air pollution in developed areas and areas deeply industrialised also contribute to the presence of this disease. Lung cancer development due to genetic factors apply to only small proportion of smokers. This predisposition may result from genetic polymorphism responsible for the metabolism of carcinogens containing in tobacco smoke and in fact DNA. There is pointing evidence for the slightly increased risk of falling ill when persons had radiotherapy of chest done in the past or  due to Hodgkin illness.
