Tumor marker ca15-3
I have have been cancer free for seven years. My doctor perform
tumor ca 15-3 at my follow up visits. It has been in the 20' s until this week and it was 112. My doctor wants to do a pet scan. I've read that sometimes the tumor marker test aren't always reliable or indicate cancer. I have a high deductible on my insurance so this will be out pocket. Not sure if I want to spend $4,000 on a test that is 50/50. Does anyone have experience with the ca15-3 test and know the reliability? Is 112 enough to be alarmed I don't even know the number when I was actually first diagnosed. I had a different doctor and he never went over my blood with me.
