CA 27-29 is a blood test that measures the level of a protein called cancer antigen 27-29 (CA 27-29) in your blood. Here are some reasons why you might consider getting a CA 27-29 test:
Monitor breast cancer: CA 27-29 is a tumor marker that is often elevated in people with breast cancer. A CA 27-29 test can be used to monitor breast cancer, track the effectiveness of treatment, and detect recurrence.
Diagnose other medical conditions: Elevated CA 27-29 levels can also be a sign of other medical conditions, such as liver disease, ovarian cancer, or other types of cancer. A CA 27-29 test may be used to help diagnose or monitor these conditions.
Screen for breast cancer: While a CA 27-29 test is not recommended as a routine screening test for breast cancer, it may be used in certain situations, such as in people with a high risk of developing breast cancer or in those who have symptoms suggestive of breast cancer.
Overall, a CA 27-29 test can provide important information about your risk of breast cancer, help diagnose or monitor certain medical conditions, and track the effectiveness of treatment. However, it’s important to remember that an elevated CA 27-29 level does not always mean that you have breast cancer, and a normal level does not necessarily rule out the presence of breast cancer. A CA 27-29 test should always be interpreted in the context of other medical information and testing.
