Can Multiple Nodular Densities In Both Lungs Cause Shortness Of Breathe?

Hi, I am a 62 yr. old female. I have been troubled with respiratory problems for the last four to five years. My Dr. says asthma, Several times in the last two yrs. I narrowlly escaped hospitilization. I almost always have shortness of breathe and at night when I exhale I can hear wheezing. A year ago after a scan I was told I have multiple nodular densities in both lungs. Could this be the cause of my problems? My father passed away from emphysema as did several of his family members, my mother from auto-immune hemolytic anemia. Could there be a genetic component for the lung disease? My physician has taken a wait and see stance. I have never smoked, however I was exposed to second hand smoke. Thanks, Mary
