The Purpose of a CA 15-3 Test

Cancer antigen 15-3, or CA 15-3, is a protein that is produced by normal breast cells. However, cancerous cells can shed CA 15-3, so your levels increase, which is why a cancer antigen 15-3 blood test is used to monitor metastatic breast cancer tumors to see how they respond to treatment or detect a recurrence of the disease. This test may also be used for people with other types of cancer associated with high cancer antigen 15-3 levels, such as ovarian, lung, and colon cancers.

What Does the Cancer Antigen 15-3 Blood Test Measure?

The blood test measures the level of CA 15-3 in the body.

Who Should Take a CA 15-3 Blood Test?

Doctors often suggest using a CA 15-3 test for patients with advanced breast cancer as a way to track the effectiveness of treatment. It may be administered on its own or along with other cancer screening tests.

CA 15-3 Blood Test Preparation

No special preparation is needed before taking your CA 15-3 test.

Cancer Antigen 15-3 Results

Regular levels register up to 30 units per milliliter. Higher levels can indicate that the cancerous tumor continues to grow or that breast cancer has returned in patients that had been in remission. However, because other benign medical conditions are also associated with high CA 15-3 levels, your doctor may also recommend other breast cancer tests for the clearest answers. We also have board-certified doctors available to offer assistance during telehealth appointments.
