Dear Dr. Mahler:

I am 64 years old and my new physician’s assistant recommended a CT scan to screen for lung cancer. Does this make sense? I take two different inhalers in the morning for my COPD and use albuterol puffer at least once most days. Each winter I seem to get a chest infection that requires an antibtiotic and a course of prednisone. There is a family history of stomach cancer, but no lung cancer as far as I know. Thanks. By the way, I quit smoking five years ago.

Mark from Kokalakis, MI
