Ask the doctor: Should I be screened for lung cancer?
Q. I smoked for 10 years during my wayward youth. I stopped 25 years ago, but now I worry about my risk for lung cancer. What can I do to prevent it? Should I be screened?
A. Fortunately, you have already done the most important thing possible to prevent lung cancer: you quit smoking. There isn't much more you can do to decrease your risk of lung cancer except avoid secondhand smoke and follow a healthy diet.
