CA 15-3 is a tumor marker often used to monitor certain types of Breast cancer. Normal levels typically range from 0 to 30 U/mL, but this can vary depending on the laboratory and the specific testing methods used. Elevated levels may indicate the presence of breast cancer or other conditions, but they are not definitive for diagnosis. Always consult a healthcare professional for interpretation of test results.
