| Pathobiological Mechanisms | CA15-3 is a glycoprotein associated with breast cancer. Abnormal secretion by tumor cells leads to an increase in serum levels, which is related to tumor burden and metastasis. | ||||
| Clinical Availability Status | Clinical auxiliary (recurrence monitoring): Used for monitoring recurrence in patients with advanced conditions after treatment, with relatively low specificity (approximately 80%), and not for early diagnosis. | ||||
| Notes and Dynamics | The value of individual detection is limited. It is often used in combination with CEA for dynamic monitoring of patients with a higher risk of recurrence. | ||||
