CA 15-3 cancer tumor marker

Posted by @elvandi, Dec 27, 2018

I’m concern since my CA 15 blood test, changed to above normal, it is up to 90. Has anyone have this issue, and with what is done to bring the marker down within normal range. Presently, only taking Anastrozole daily. Do have a lot of muscle pain recently.

Just saw your post and read it because I also take Anastrozole daily. Can't address blood test question – just wanted to most sincerely wish you well.

Glori, Any abnormal test will set off alarm bells and anxiety. I'm sure that is how you're feeling with the higher than normal levels of cancer antigen 15-3 (CA15-3) in your recent blood test. But remember, it's just an indicator, signalling that further testing is necessary to find out IF anything is wrong. When do you see your oncologist to discuss the results and get further testing?

Just thought I’d throw this out there-my oncologist at Dartmouth-Hitchcock does not test routinely for cancer markers as he says the test is unreliable and has many false positives and false negatives. He has been over 30 years practicing, so he has a lot of experience to back his opinion. Hopefully your elevated levels are an example of this. Best wishes.
