CA 15.3

Cancer Antigen 15-3 (CA 15-3) is indeed a protein used as a tumor marker, particularly for breast cancer. Monitoring CA 15-3 levels helps assess the progression of cancer, evaluate the effectiveness of treatment, and detect potential recurrence. However, elevated levels of CA 15-3 can also be seen in other conditions like colorectal and lung cancers, liver diseases (e.g., cirrhosis, hepatitis), and even benign breast diseases, which makes it a useful but non-specific biomarker.

Mydoctorlab offering the test with added conveniences, such as discounted pricing and free home collection, can make it more accessible for regular monitoring. For individuals managing cancer or at risk of recurrence, this could be particularly beneficial.
