Prevention:
Overwhelmingly, the most effective way to prevent lung cancer is to not smoke or to quit smoking if one has already started. Secondhand smoke should be avoided as much as possible. Appropriate precautions should be taken when working with cancer-causing substances (carcinogens). Monitoring the diet and eating well-balanced meals that consist of whole foods, vegetables, and fruits; eliminating toxins, exercising routinely, and weight reduction; testing houses for the presence of radon gas; and removing asbestos from buildings also are useful preventive strategies.
