Little rise in tumor markers, terrified

Hi everybody,

I know markers for somebody work, for somebody not...i'm talking about CA 15.3

Mine were high before the cure, and low when cancer was stable (i started Capecitabine September '23).

they were always about 20/23. Now they went up to 31.7

Normality is up to 31, but the 35% increase really scared me. I have a PET at the end of April, but I'm terrified.

Did anyone with a working markers history had an increase and it end up been nothing?

I know it is different to everyone, but i looking for some hope!

Thank you snd best wishes everyone!
