Wasn't sure where to put this, so I put it under this topic.
If your CA 15-3 and CA 27-29 increase but are still within normal limits, does that mean anything?
When I was diagnosed, mine were in normal limits, but on the higher end. Now I'm being evaluated for recurrence and they have both increased but still within normal limits and still lower than they were when I was first diagnosed in 2017.
Do these numbers fluctuate often?
