I had blood work 4months ago and then just this past week. My CA 27.29 jumped 10 points in that time and is now out of the normal range…49. I had surgery in April and radiation in July of 2018. I have been taking anastrozole since last May. Has anyone else had this experience? Of course I am afraid. Can stress affect tumor marker readings? My doctor is sending me for a CT scan. Is this a “normal” occurrence?
