Glucose antigen 153, also known as CA15-3, is a blood test that aids in the diagnosis of breast cancer and also allows dynamic monitoring of postoperative recurrence and treatment outcome of breast cancer through changes in the index value.
Elevated CA15-3 can also be detected in the blood of patients with other systemic malignancies, such as lung, colon, and pancreatic cancers. In addition, other non-malignant diseases such as gastrointestinal, lung, and hepatobiliary can also show elevated CA15-3.
It is important to know that an elevated CA15-3 does not necessarily mean that you have a malignancy either. The first thing you need to do is to get a good idea of what you are getting into. If there are abnormalities in other indicators, it is recommended to consult the relevant departments in time to clarify the diagnosis for precise treatment. If the index is only elevated, and the index is not significantly elevated, and other tests are not significantly abnormal, the index can be reviewed regularly. If the elevation persists, it still needs to be taken seriously.
