question: Hi , I am a 54 yr old female, smoked 5 cigs a day, 10 on weekends for 30 yrs. CXR showed interstitial scarring of lungs. I run 1 hr a day with out any problems. Should I be concerned? See a pulmonologist? It also said mild estasia at the thoracic aorta. They did not suggest  I get any further testing. Thank you.
