Brain MRI questions? scared!

[Alice]

Hi,
I have been out of the loop for awhile. I am glad to see some of the names I remember. I am going for a brain and spine MRI in a couple of days. I had a brain MRI last year and it was fine. I am anticipating this one will be fine also. I do have a question regarding my bloodwork though. My WBC's have never come up to normal after treatment. The best they were was 3.7 about 2 years ago and now they are at 3.1. It seems to range from 1.7 to 2.9 most of the time. My onc says that we need to just keep an eye on it to make sure that I don't have a syndrome going on. Has anyone had this type of problem? I am just worried about getting a secondary cancer like Leukemia or something.
