I'm going to say the impossible - don't worry. I know that is easier said than done. But as you said, you don't have all the results of your lab work yet. These indicators really require the interpretation of our oncologist to know what they mean for YOU.

According to the OncoLlink Patient Guide to Tumor Markers (https://www.oncolink.org/cancer-treatment/procedures-diagnostic-tests/blood-tests-tumor-diagnostic-tests/patient-guide-to-tumor-markers)
"CA 15-3 is used for monitoring breast cancer, lung, ovarian, endometrial, bladder, gastrointestinal. CA 15-3 can also be elevated due to conditions other than cancer such as liver disease (cirrhosis, hepatitis), lupus, sarcoid, tuberculosis, non-cancerous breast lesions.
(Note: 30% of patients have an elevated CA 15-3 for 30-90 days after treatment, so wait 2-3 months after starting new treatment to check.)"

Starko, when did you complete treatment?
