My experience. Markers are an indicator not results. The only way to determine if you have cancer or not is a PET scan and consequently a biopsy, if PET show cancer.
For three years my monthly 15-3 markers were in the high 20's. Then a jump to 56, 101, 156 and 190. In retrospect the wait between 56 and 101 was unnecessary. I would have started my treatment a month earlier.

@ampeltekian did your oncologist do monthly markers after your initial diagnosis or were you stage 4? My docs don't do blood tests so there really is now good way to determine if cancer has recurred/spread.
