CA-125: Full Form and Overview
CA-125 stands for Cancer Antigen 125. It is a protein that is often found in higher levels in the blood of women with certain types of cancer, particularly ovarian cancer.
Key Points about CA-125:
- Biomarker:
CA-125 is used as a tumor marker to help diagnose and monitor treatment for ovarian cancer.
Normal Levels:
A normal CA-125 level is typically less than 35 units per milliliter of blood. However, this can vary based on the laboratory and individual circumstances.
Uses:
- Diagnosis: While not used for initial diagnosis, elevated CA-125 levels can indicate the presence of ovarian cancer.
Monitoring: It is often used to monitor treatment response and check for recurrence of cancer after treatment.
Limitations:
- Elevated CA-125 levels can also be seen in other conditions, such as:
- Endometriosis
- Pelvic inflammatory disease
- Menstrual cycle
- Pregnancy
- Therefore, CA-125 is not a definitive test for cancer and should be used in conjunction with other diagnostic methods.
Conclusion
Understanding CA-125 is crucial for women’s health, particularly in the context of ovarian cancer. Regular monitoring and consultation with healthcare professionals can help in early detection and effective management of potential health issues.
