Ca 27.29 consistently high...in the 40’s

Hi Thessf14, and welcome. Variations in tumor markers test like the CA 27-29 can be disconcerting and stressful. As @cindylb aptly said in an earlier message in this thread "Tumor marker tests are one tool doctors have to monitor but they can have great change and variables." And @mom23boys said "people's numbers bounce around and no two people seem to have the same starting point or "normal"."

Tumor markers are a simple non-invasive test that can give a signal for further investigation – the proverbial canary in the coal mine. Sometimes the fluctuations may indicate a progression of disease and sometimes not.

I'm sorry that you got this reading on a Friday going into the weekend, especially when it may mean nothing. Were you able to talk to your oncologist today or to leave a message on your patient portal? What type and stage of breast cancer do you have?

Hi Colleen. Thanks for the info. I was diagnosed June 2020 on my left breast. Stage 1. I decided to go for Double Mastectomy. Nothing on my lymph nodes, and no chemo also. The first time, January 2021, I had the 27-29, the result was 26. Last Friday, April 30, I got the result for my 27-29 as 36, and the result for my 15-3 as 21. You think numbers are small?

When I asked my oncologist about these tests – she stated she does not use them at all because they are unreliable. I trust her – so I'm not concerned with these tests. I was a Stage 1 – 3B tumor. Lumpectomy, no chemo, but radiation.
