I had a ct scan done. the doctor told me i was showing signs of mild emphysema. everything i find on the internet is negative and scary. i wasn't sure what this meant and prognosis.

COPD: Emphysema is a chronic medical condition, most often associated with tobacco smoking. Emphysema or COPD, chronic obstructive pulmonary disease is basically an inflammatory response of the lungs to long term exposure to an irritant. If you are a smoker, stop immediately to prevent further progression. Please do not be scared, but instead be informed as to the preventive measures you can take.
