<s>[INST] I have been just told that I have mild signs of a fatty liver accidentally noticed in a recent CT scan. Alcohol could be a cause but although I am no where near an alcoholic, I probably have 6 standard drink per week. I also have some scarring in the right lung. This may be caused by an old infection, but maybe exposed to passive smoking many years ago (I have never smoked) or I am on the road as a sales representative for many years (exhaust fumes, asbestos fibres from car brakes?) Your thoughts? Should I consider giving up my current job. [/INST] Thanks for your question on HCM.I don't think you are having active infection. As CT Scan clearly indicates fibrotic scar like lesion.In lung tissue healing occurs by either fibrosis or calcification. So any past insult to the lung either infection or trauma heals by either fibrosis or calcification and left the scar. This scar will remain life long.So presence of scar tissue does not mean that you are having lung infection.So no need to worry. Continue your job. Avoid alcohol if possible. </s>
