I had a blood test, CA 27 29, after my protocol last year, and then a mammogram and ultrasound at the hospital...I have a limited insurance thru a hospital plan...they won't do other tests.
Now, I read that CA 27 29 is only 58% accurate. I know one should not depend only on a bloodtest. However, I don't have anything else but muscle testing, which I can go for, in addition to the blood test.
Which blood test do you think is most accurate, not that any of them are great?
