Preventative measures remain the best option to fight lung cancer despite the advancements made in therapeutics and diagnostics. One major risk factor of lung cancer is tobacco smoking, causing 80% of lung cancer deaths. Exposures to other chemicals like radon and diesel exhaust also cause lung cancer. Preventing these exposures will allow for great strides to be made in preventing lung cancer and decreasing the number of new cases and deaths.

On the individual level, following cancer treatment it is important for the patient to eat healthy, get exercise, obtain regular check ups and most importantly stay away from risk factors like tobacco, radon, and diesel exhaust. Lifestyle changes are often associated with a better prognosis and higher quality of life after treatment, and therefore should be a top priority for anyone recovering from NSCLC.
