I have had 4 ct scans in the past year.The first on detected multiple scattered nodules with an irregular shape.They are 2mm to 7mm.The ct scan I recieved last month shows that I have new small nodules.One of the 6mm nodules shrunk to 4mm.I have never smoked.I painted my popcorn ceiling 10 years ago and recently found out that there was asbestos in it.I also tore up some linoleum tiles in my kitchen and bathroon 2 years ago and later found out that they had asbestos in them.I read that multiple,irregular and new nodules increases the chance of malignancy.It the chances are 80% that they could be.I am also concerned about all the radiation I am getting from all these ct scans.I read that a ct scan has 50 times the radiation of a chest xray.I also read that the chance of getting cancer from a ct scan is 1 in 100,which is not small.i was also told that a biopsy done on my small nodules can be a tough one.I think I am faceing a real dilemma,and a lot anxiety about what to do.Based on everything are there any nodule experts that might be able to guess what the chances are that the nodules can be malignant?And what should I do? Thank You
