Sep 19, 2018 · Ca-15-3 can be used to monitor the response to breast cancer recurrence treatment. However, the results alone cannot be the sole guide to predict the occurrence of metastatic spread. False positive results in raised Ca-15-3 can also be caused by non-cancerous conditions, the list is quite long.

Apr 12, 2020 · Hi ShadyLady, Thank you for the response! I've heard if my situation is non-cancerous, then the CA 15-3 level should hold about the same when the blood test is done again. The ton of supplements can be a factor too. I'll need to back off on a few to give my liver a break.

Mar 10, 2012 · CA 15-3 does not cause cancer; rather, it is shed by the tumor cells and enters the bloodstream, making it useful as a tumor marker to follow the course of the cancer. CA 15-3 is elevated in about 10% of women with early localized breast cancer and in about 70% of those with metastatic breast cancer.

Oct 9, 2013 · Hi dear sisters, I just had CT scans (chest, abdomen & pelvis) that show NED, but two days later my CA 15-3 is up though still within normal limits.

Oct 19, 2020 · Allstar, My dr. doesn’t even want to include the CA 15-3 in my monthly blood panels because he feels the test is too unreliable to be meaningful. If yours has been stable for two years, then maybe that value is normal for you. Instead, my doctor prefers to use the breast cancer tumor marker CA 27.29 and the general tumor marker CEA.

Jul 3, 2021 · Newly diagnosed IDC of breast with stage 4 Mets to bone. My oncologist ordered baseline blood work and my CA 15-3 is 140. I’m starting

Jul 29, 2013 · I am wondering if anyone knows the difference between CA15-3 & CA125 Tumor Markers. In my research I found that CA15-3 is for breast cancer and CA125

Apr 7, 2010 · i was followed with CA 27-29 for the first 2 yrs, but then they switched to CA 15.3 because it is a cheaper test. i was told at the time, and again since, that it is "the same thing", but in reading the articles at the above link, i see that they actually DO look at different things.

Jun 12, 2018 · CA 15-3 and CA27-29 both recognize MUC1, although each of those recognizes a different region of the protein; both differences that are present in the original non-cancerous cell and changes that occur over time on the cancer cells may make these markers less reliable; also, other markers (CA125 and CEA) May also be present on breast cancer ...

Apr 30, 2015 · Evening, all. I just had my blood work done today - all looked good except for the CA 15-3 - it went up from 12 (last month) to 16 (today). I have had it as high as 19 in the past and then it trends down to 10 or 11, then it wobbles between 12-13-14. To me, 4 points is A LOT, but it is still way below range of 30 (?).
