Sorry Colleen

I think I created unnecessary confusion. It was panic mode.

Yes it is recurring BC. I have been on ribociclib/letrozole for two months now. Not three.

My markers are climbing. The last Pre treate ca15-3 was 142 u/ml.

1st round of post treatment it was 156

2nd round of post treatment it is 190.

So the panic button

Any input would be super helpful. Early pet scan?

Also, what type inflamation could cause inaccurate readings? Muscular?

Thanks
And my appologies
