    How reliable is the CA27.29 Blood Test in detecting Cancer Recurrence

    I am a 65 yr. old TNBC, BRCA 1&2 negative 5 yrs. this June survivor. Mom died of breast cancer in her 40's. 6 months ago my Oncologist decided to use the CA27.29 which came back as 41. On 5/7/2019 it came back 12 points higher at 53. Prior to the CA27.29 CEA and CA15-3 were normal. Oncologist wants to repeat CA27.29 in 1 month. I am beside myself with worry. Should I be?

      Today I had my annual thermography scan. I do that annually and also if I have a “scare”. It gives me comfort to be able to get this alternative view of what’s going on in my body. I am mentioning it because the original question in this thread was about monitoring for cancer recurrence. Thermography is another option for checking yourself. There is no definitive test short of a biopsy but you can layer the “soft” findings from whichever tests you have access to: cancer markers, thermography scans, blood work, bone scans, and MRI’s. You can at least get a sense of where you are. The fear of recurrence causes so much anxiety for all of us. Hugs & prayers, Judy in Ky

      TX. I watched video about the thermography and was surprised about the two studies came out about not so good after effects of mammography with the radiation and the smashogram effect possibly spreading the cells.

      Hi NervousNellie - I completely understand. I am Metastatic - 6 yrs this August. My Oncologist has me do markers every 30 days - CA 27.29 and CEA. Ever since I started Ibrance/Faslodex three yrs ago my CA 27.29 has been literally all over the place. For example, last month it was 58.3 (my hospital's lab has a standard high range of 40). Today it came back at 44. When this started happening, my anxiety was off the charts. When she told me that if and when the CA 27.29 doubles (80 or higher) at that point she will get concerned. Until then, as long as the CEA is within the normal ranges, not to worry. I know everyone is different, but I hope this helps a little.
