@lgray3911 I can only imagine your anguish and rightfully so, there just isnt any way of settling how you feel without your Oncologist and his trusted opinion by you. I've not heard that cording shows up in scans, and not sure about yellow? color, not heard of that either. It doesnt necessarily mean Cancer I'm with you. I know it's so incredibly hard to not drive yourself crazy trying to work everything little thing out, your Oncologist is the best way to ease your mind. Step at a time.
I know how you are feeling, I've been down this path, but this does not mean you have a recurrence at all, just remember that. Slow and steady.
Sending you good vibes, that it is absolutely nothing to worry about! xx M
