Is the news "not good" or "bad"

Test results show my tumor markers climbed a few points again. This testing, performed at the same time as my last PET/CT, contradicts the results of the scan. So which is true? Or are both correct which may mean that there are sleeper cancer cells somewhere making my numbers go up while the tumors we have been watching aren't growing.
But, there's nothing to be done about any of it until the tests on today's blood come back.
If markers are climbing then the regimen changes. If they aren't climbing then we move forward. But, I have questions about why my tests are up and down like a roller coaster.
I am frustrated. I am tired of wondering why the struggle to get progress againt these tumors.
Ugh!
