In 2015 my breast cancer returned. It is Stage IV - in lymph nodes under my sternum area. I was on Ibrance for 4 1/2 years but it stopped working in early 2019. Two new spots appeared in the lymph node. Four of the 5 spots were only a few millimeters in size. One spot was 1.5 centimeters. I started a clinical trial in June 2019. I am taking Faslodex every 4 weeks. I have a CT Scan every 8 weeks. Initially saw some reduction in the spots. Last scan in January 2020 showed no progression - stable… read more
@A MyBCTeam Member I do believe the CA 15.3 & CA 27.29 are only used for Stage 4 Breast cancer.
What is a CA 27.29 test used for?
The CA 27.29 test is used for measuring how cancer is progressing and how the body is responding to treatment.
A CA 27.29 blood test looks for a specific type of tumor marker produced by the MUC1 gene. Elevated levels of this type of cancer antigen may be found in patients with metastatic breast cancer, meaning breast cancer that’s spread to distant areas of the body. For this reason, clinical guidelines recommend that tumor markers are used for metastatic breast cancer only and not for screening, diagnosing or monitoring localized breast cancer.
Other types of cancers and noncancerous conditions may show elevated 27.29 levels, which is why tumor marker tests are often used in combination with other
tests.
I lie down for my PET scan. When I was diagnosed with Mets in June of 2017, scan revealed pathological fracture in my left femur. I was immediately put in the hospital and not allowed to walk until a titanium rod was placed in the bone from hip to knee.
@A MyBCTeam Member Mine are being checked every 2 months now. My tumor markers keep going up. I just had my CT and bone scans. Sure enough there's 2 tumors in my lungs getting bigger. She thinks the ibrance isn't working as well as it did. I meet with her this Friday to discuss different treatment, and/or biopsy. We'll see. Markers are like red flags. It indicates changes going on that might warrant further tests. Sending prayers up for you.😊👍🙏🏻
At what point are they supposed to check tumor marker. 16 months on exemestane and never had that done
If your tumor marker continues to rise, it may indicate that the cancer is not responding to the current treatment. It's important to discuss this with your healthcare provider to explore other treatment options. As one member mentioned, "Luckily with new treatments being developed all of the time, there is always something Show Full Answer
