brain scan

[sally]

I got the results of my brain mri. Everything looked normal and good. My tumor markers have gone up again. I think the doctor said they were at 184. I don't really know what that means. I haven't paid attention to the blood work. It has always been normal and that was enough for me to know. Now I have been taken of Femara and put on Tamoxifen to hopefully bring my tumor markers down. My PET and my liver mri also came back normal. I guess I have active cancer based on the blood work but it isn't visible on the scans. Is that because it is too small to see? My doctor said that it is normal for markers to go up while I am on Tamoxifen so it will be a couple of treatments before they can see if it is working. I still get Herceptin every three weeks. Has anyone received chemo based on tumor markers only? Or do you have to see it on a scan first before you get the chemo? Thanks for any words of wisdom. Sally
