Hello friends. I along with some others on this board have wondered about upward movement in our CA15 tumor markers during our monthly blood labs. Today I met with my oncologist following my semi annual CT and blood scans. I am 2 years into MBC.
I was apprehensive because the last 3 month blood labs showed small but identifiable upward trends in my CA15.
The great news is my scans are clean!! Phew! I’m good to go again thank goodness
When I asked about the markers, she said to think of the change as more like a “squiggle.” In other words, some variance is not unusual. It’s not like some bad sort of “hockey stick” trajectory over months and months.
It is a good reminder to me to focus on the whole set of tests. The bigger picture is more informative. I will try not to fall into this rabbit hole again with my markers. I will embrace that Ibrance and letrozole are still working.
Hope this helps some of you.
