ca15-3 breast cancer

Release time ：Nov-08,2024

CA15-3 is a blood-based tumor marker that often elevates in individuals with breast cancer. However, an elevated CA15-3 level does not definitively indicate breast cancer, as it can also be raised in other types of cancers and some non-malignant conditions.

When clinicians suspect breast cancer, they may include CA15-3 testing in their diagnostic workup. A positive result, indicating levels above the normal range, typically warrants further investigation to ascertain the presence of breast cancer or other malignancies.

It's important to recognize that CA15-3 lacks specificity as a tumor marker; its elevation could be associated with various cancers or non-cancerous diseases. Consequently, CA15-3 levels should not be the sole basis for a breast cancer diagnosis and must be interpreted alongside other test findings and clinical signs.

For patients with a confirmed breast cancer diagnosis, CA15-3 testing can aid in tracking disease progression and therapeutic efficacy. A sustained decrease in CA15-3 levels within the normal range during treatment often signals a positive response to therapy. Conversely, an increase or persistently high levels may suggest disease progression or inadequate treatment effectiveness.

In conclusion, CA15-3 is a significant tumor marker with value in diagnosing and monitoring breast cancer. However, due to its non-specific nature, it should be considered in conjunction with other diagnostic results and clinical presentations. For any inquiries or concerns regarding CA15-3 testing, consulting with a healthcare provider is advised.
