Dear sir, I went for x-ray test in 2013 that time they said you have lungs scar (fibrosis in lingula), then I check with another centre they said no issue in your lungs, so for I taken around 6 time x-ray test they found no scar in my lungs, next month my visa renewal. again they will ask me to go for x-ray test. Can you clarify my doubt this time is there any possibility to detect my lungs scar, actually I never had TB so far. Then what type of lungs scar this. Please help.
