Hi Trudy and welcome.

To help you connect with other members like @lisakinpa @jemma17 @lazomama @mssewest @cctoo, I moved your question about interpreting CA 27-29 results to this existing discussion:

– CA 27-29 numbers rising: Does anyone else have an issue like this? https://connect.mayoclinic.org/discussion/ca-27-29-consistently-high-in-the-40s/

You may wish to read the previous messages to see that CA 27-29 is not used alone to monitor breast cancer. A single value is less important than how the results trend over time. Thus the test is generally used to monitor and notice whether there is a change in your values.

Were all your CA 27-29 tests done at the same lab? Where were the small nodes shown on the CT scan?

My oncologist and I agree that many factors can elevate our CA27-29 numbers, even what we’ve eaten and certain physical activity that took place the days prior to the test.

Therefore, we decided together to discontinue having this test done, and, instead, rely on my bloodwork, physical exams and yearly mammograms.

My oncologist felt the tumor marker was most helpful for those with late stage breast cancer so that they can monitor the effectiveness of treatment lines. ♥️

That is not a big jump and still under 38 so in the normal range. Good to keep watching and asking questions!
