The CA 15-3 test measures the level of Cancer Antigen 15-3 in the blood, which can be elevated in some cases of breast cancer.
Test Procedure:
A blood sample is drawn from a vein, and the concentration of CA 15-3 is measured in the laboratory.
When to take the test:
The test is recommended for monitoring certain breast cancers, assessing response to treatment, or detecting disease recurrence.
Who should take the test:
Patients with breast cancer undergoing treatment, those at risk, or those being monitored for disease progression might require this test. It’s usually ordered by oncologists or breast specialists.

Frequently Asked Questions (FAQs) for Ca 15-3 (Breasts) Test:
Q1: Can CA 15-3 levels be elevated in conditions other than breast cancer?
A: Yes, elevated CA 15-3 levels can also occur in other conditions like lung, ovarian, or pancreatic cancers, as well as benign breast conditions.
Q2: How accurate is CA 15-3 in detecting breast cancer?
A: CA 15-3 isn’t a definitive screening tool for breast cancer. It’s used more for monitoring disease progression or response to treatment.
Q3: Can lifestyle changes impact CA 15-3 levels?
A: Lifestyle changes usually do not significantly affect CA 15-3 levels. However, overall health practices contribute to early detection and disease management.
Q4: How often should CA 15-3 levels be monitored in breast cancer patients?
A: The frequency of testing depends on individual factors, treatment plans, and disease status. It’s determined by the healthcare provider.
Q5: Can CA 15-3 levels indicate the stage of breast cancer?
A: CA 15-3 levels might provide some indication of disease progression, but they aren’t used alone to stage breast cancer.
