Lung cancer is one of the leading causes of death worldwide, and although smoking remains the most well-known risk factor, there are many other factors that contribute to its development.
Understanding the various risk factors for lung cancer is crucial for early detection and more effective prevention.
In this article, we will explore not only the effects of tobacco but also other elements that influence the risk of developing this disease.
Smoking: the main risk factor
Smoking is undoubtedly the most significant risk factor in the development of lung cancer. It is estimated that 80% of lung cancer cases are related to tobacco use.
Cigarette smoke contains more than 7,000 chemicals, many of which are carcinogenic. The risk increases with the number of cigarettes smoked and the duration of the habit.
Cigars and pipes have almost the same likelihood of causing lung cancer as cigarettes. Factores de riesgo para el cáncer de pulmón
Exposure to air pollution
Air pollution is another significant risk factor for lung cancer, especially in urban areas.
Prolonged exposure to air pollutants, toxic gases, and industrial chemicals can severely affect lung health.
Hereditary factors and family history
The risk of developing lung cancer can also be influenced by genetics. People with a family history of lung cancer have a higher risk of developing it, even if they do not smoke.
If you have a family history of lung cancer, it is important to talk to a doctor about the possibility of undergoing screening tests.
Occupational exposure to carcinogens
Some professions can increase the risk of developing lung cancer due to constant exposure to toxic substances.
Asbestos, a material used in construction and industry, is one of the most well-known occupational carcinogens.
Workers who handle asbestos, such as those in construction, mining, or product manufacturing, have a much higher risk of developing lung cancer.
Preexisting lung diseases
People who suffer from lung diseases such as chronic obstructive pulmonary disease or pulmonary fibrosis have a higher risk of developing lung cancer.
These conditions damage the lungs and increase inflammation in lung tissues, which can facilitate the development of cancer cells.
Arsenic in drinking water
According to the American Cancer Society, some studies conducted on people living in parts of Southeast Asia and South America where there are high levels of arsenic in drinking water have found a higher risk of lung cancer in those individuals.
In most of these studies, the levels of arsenic in the water were many times higher than the levels generally recorded in other countries such as the United States.
In conclusion, while smoking remains the most well-known risk factor for lung cancer, there are other factors that can contribute to the development of this disease.
Exposure to air pollution, radon, family history, occupational exposure to toxic substances, and certain pre-existing lung diseases are just some of the additional risks you should consider.
Preventing lung cancer is possible, therefore, it is necessary to try to maintain a healthy lifestyle, be informed about the different risk factors, and also have clarity on how they can affect your health.
