Hi. I would assume this is a benign nodule but can you tell me a bit more please--
How large is it, how was it discovered, and are you a smoker?
I am a non smoker, the size is 1 1/2 cm, it was discovered by a CT scan.
OK. Then it's appearance must suggest it it a benign nodule--probably an old granuloma from a previous lung infection.
About 95% of these are totally benign and the standard of medical practice is to follow it with a ct scan every six months or thereabouts for a few years.
If it enlarges or it's appearance changes in that time period, then it is biopsied
Let me know if you need any more information about this please, Tracy
