I just had a CT done on my neck with IV contrast to look for swollen lymph nodes. Nothing was found BUT, apparently they saw a small cyst in my chest. Since the CT wasn't focussed on my chest, my doc wants me to get another CT w/ contrast. My appointment is a exactly a week after my prior app. I also had a CT done on my sinuses, no contrast, in November.

My question is...is this safe? I am a little concerned about exposing myself to MORE radiation and contrast. Obviously, I still want to get it done to find out what the cyst is...but now I am worried about the risk with the CT.

Thanks!
