2. What Causes NSCLC?
While doctors still can’t give exact cancer causes, a few patterns have been noted in past patients. Smoking cigarettes may be highly associated with being the leading cause of lung cancer, but NSCLC patients prove it is not the only reason. Non-smokers who consume secondary smoke, especially those living in residence with a smoker have a 24% chance of developing lung cancer due to passive smoking, also dependant on the number of years spent exposed to a smoking partner. Exposure to asbestos fibers also leads to NSCLC.
The most commonplace of influence would be the workplace which is why; it has either been restricted or banned in the US and a few other countries. Air pollution, as well as gases like radon which is an odorless gas found in many US homes, can lead to cancer. It is important to have your homes tested for the gas. Lastly, family genetics are believed to play a role in diagnosis.
