 
Though lung cancer remains the number one cause of deaths from cancer, its incidence cannot be fully understood by some factors alone. While the primary causes include smoking and some other carcinogens, alarming trends revealing rising lung cancer rates among nonsmokers raise fundamental questions regarding causative factors and prevention.
The Rising Trend
A significant surge in lung cancer has recently been observed in the category of nonsmokers. This is an alarming trend, as it is confusing and creates quite a riddle among experts. The increase in this cancer has been associated with several environmental and genetic causes. Hence, their impacts become essential for knowledge purposes regarding prevention and awareness.
Environmental Factors Involved
Air pollution is one of the most common reasons for lung cancer. The automobile and industrial emissions lower the air quality in cities. Several studies have shown that a high incidence of lung cancer goes directly proportional to the degrees of pollution. Furthermore, secondhand smoke has been proven highly dangerous for non-smokers too. In fact, a person who lives with the smoker is at much more risk of developing lung cancer.
Radon Gas: The Silent Killer
Another significant source of threat is radon gas. Radon is a colorless gas that has no smell. It forms naturally through the ground and occasionally builds up in buildings primarily in the basement areas. The U.S. Environmental Protection Agency states that a large number of lung cancer cases that occur among non-smokers can be attributed to some percentage of radon. Checking the levels of radon in buildings could be useful in identifying invisible threats.
Family or Genetic History
However, other genetic factors cause the development of lung cancer also. Individuals have some mutations present within their bodies that can even risk the disease without smoking. Some of these genes are found and discovered with recent research into the genetic basis of this disease. Understanding one’s genetic makeup, therefore can help to better understand an individual’s risk level.
Role of Diet and Lifestyle
There is the element of diet and lifestyle determinants that may bring along risk exposure to lung cancer. An example of such influence comes about through a low consumption diet of fruits and vegetables; this will most definitely lead to weakened immune capability for the body. This scenario is opposite if several different fruits and vegetables are being consumed. Healthy status results from consuming multiple types of fruits and vegetables. Further, exercise maintains functional activity in the lung with positive effects on a whole life. It then contributes significantly to lowering risks towards attaining cancer cases.

Some occupations expose a person to dangerous substances. A good example is construction or manufacturing. An individual working here is liable to be exposed to carcinogens such as asbestos. Thus, this occupational exposure highly increases lung cancer rates. Strict regulations regarding security and protective tools will alleviate the risks.
Early Detection Is Essential
The most important aspect of improving the outcomes of lung cancer is early detection. Screening tests that are conducted periodically detect lung cancer in its earliest stage. Non-smokers who have risk factors must undergo annual screenings. In addition, awareness of symptoms such as persistent cough or unexplained weight loss is very important. Consulting a healthcare professional right away can help to act in time.
Public Awareness and Education
The public should be enlightened about the dangers of lung cancer. Most people still do not know that lung cancer may affect non-smokers. Such campaigns may work toward creating a healthier lifestyle for more people. Environmental dangers may also be included, as awareness can work toward preventing them.
Importance of Research
There is still much research to be conducted regarding lung cancer. Scientists are trying to study many of the causes that are currently contributing to its increase in non-smokers. Innovation in treatment and prevention requires thorough studies. Funding research may lead to a breakthrough that saves lives someday.
Conclusion: Lung Cancer Action
With a strong concern for the rising nonsmoking lung cancer rate, we pay attention to all factors responsible. Environmental conditions, and also genetic investigations are boosted and diagnosis improved. People are informed first before knowing. Knowledge and wisdom about healthy lifestyles would keep them away from all other cancers and lead to lesser percentages of lung cancers. That’s how the threat by lung cancer upon the nonsmoker population may vanish as time passes and so that it will definitely see our day. click here for the source
