Ordering the CA-125 Ovarian Cancer Antigen Test
Ordering the CA-125 Ovarian Cancer Antigen test is a significant step in monitoring ovarian health. This blood test measures the level of cancer antigen 125, a protein that can be elevated in ovarian cancer cases. Interestingly, while CA-125 is primarily associated with ovarian cancer, it can also be elevated in other conditions like endometriosis, making it a versatile diagnostic tool.
Here are some specific benefits of the CA-125 test:
- Helps in the early detection of ovarian cancer.
- Monitors treatment effectiveness in diagnosed patients.
- Assists in evaluating the risk of cancer recurrence.
- Provides insights into other potential gynecological conditions.
- Supports decision-making for further diagnostic procedures.
Who Should Consider the Test
Women with a family history of ovarian cancer or those experiencing persistent symptoms like bloating or pelvic pain may find this test beneficial. For instance, a woman with a history of ovarian cysts might use this test to monitor changes over time.
Other scenarios where the CA-125 test might be considered include:
- Women undergoing treatment for ovarian cancer.
- Individuals with a genetic predisposition to ovarian cancer.
- Patients with unexplained pelvic pain.
- Women with endometriosis seeking further evaluation.
- Those with a history of pelvic inflammatory disease.
Consider ordering the test if any of these situations apply to you.
How to Prepare for the Test
No fasting is required for the CA-125 test. If you are taking medications or supplements, ensure you follow any specific instructions given by your healthcare provider.
