I have a little lum in my left lower lung what could it be?Im 51, female, 56, 154 lbs.  Healthy, however have arthritis.  lately i felt a pain in my right rib area, my doctor requested a chest xray, it indicated a lump on the left lung, but was told not cancerous.  What could it be then?
HIIT probably is a granuloma--a remnant of a prior lung infection need a ct scan of the lungs to better define it and another scan in about six months to see if it increases in size.  If it doesn't, then it is benign
