question: Hi, I was just curious in my case. I have this very small spot in my lower right lung when I had my x-ray for my medical but as I remember, I had my x-ray way back in my college days but there was no spot found. The doctor said that I need to see a pulmonologist to examine my x-ray result. My mother said that I had my medication in my lungs when I was a child for about 6 months. Im a bit scared if its contagious did it already affect any person Im with?
