Description
The CA 27.29 blood test measures the level of Cancer Antigen 27.29, a protein that serves as a tumor marker to monitor metastatic breast cancer. While it is not used for breast cancer screening, it is an important tool for tracking disease progression and response to treatment in diagnosed patients.
Why the CA 27.29 Test Is Important
- Monitoring Progression: Higher CA 27.29 levels can indicate more advanced or spreading metastatic breast cancer.
- Evaluating Treatment Response: Declining levels suggest that therapy or treatment is effectively controlling the disease.
- Treatment Guidance: Helps healthcare providers adjust treatment plans based on tumor activity.
When the Test May Be Ordered
- After a breast cancer diagnosis to monitor if the cancer has spread.
- During treatment to track whether therapy is reducing tumor activity.
- Individuals experiencing breast-related symptoms, including:
- Lump in the breast
- Bloody nipple discharge
- Changes in breast or nipple shape or texture
- Redness or swollen lymph nodes
Fasting: Not required.
