Mucinous Carcinoma Antigen (MCA) Test

The Mucinous Carcinoma Antigen (MCA) test measures a specific protein marker that can be elevated in certain mucinous cancers, particularly mucinous carcinoma of the breast. It is used as an aid in monitoring disease progression, assessing treatment response, and detecting possible recurrence in patients with a known history of mucinous breast carcinoma. This test is not a general screening tool for the presence of cancer in healthy individuals, and it is not intended to replace clinical examination, imaging, or other diagnostic procedures. It is most appropriately requested by a specialist or oncologist as part of a broader clinical assessment.

Marker Included
- Mucinous Carcinoma Antigen (MCA)

Who it is for
- Patients with a confirmed diagnosis of mucinous breast carcinoma who require monitoring during or after treatment.
- Individuals being followed up for possible recurrence of mucinous breast cancer.
- Clinicians seeking an additional biochemical marker to complement imaging and clinical findings in the management of mucinous breast cancer.

Why it matters
MCA can provide useful information about disease activity in mucinous breast cancer. Serial measurements over time may help your clinical team understand how a tumour is responding to treatment or whether there are signs of recurrence. Because MCA is not specific to a single cancer type and can be influenced by other conditions, results are always interpreted alongside your medical history, physical examination, and imaging studies. Your doctor will discuss what your MCA result means for your individual care.

No special preparation required.

For blood tests, we recommend drinking plenty of water beforehand to ensure smooth sample collection. If you are taking any regular medication, continue to do so unless advised otherwise by your doctor.
