Description

Cancer antigen 15-3 (CA 15-3) is a circulating mucin-type glycoprotein fragment most commonly used as a tumor marker in breast carcinoma. While not recommended for primary screening, CA 15-3 provides valuable information for monitoring therapeutic response and detecting disease recurrence.

Indications

Treatment monitoring in patients with known metastatic or advanced breast cancer

Surveillance for recurrence following definitive therapy

Adjunctive assessment of disease burden in conjunction with imaging and clinical examination
