what are cancer markers for breast cancer

Release time ：Nov-10,2024

Typical biomarkers for breast cancer include CA 15-3, CEA, and CA 125, which assist physicians in evaluating the disease and monitoring therapeutic outcomes.

CA 15-3, a glycoprotein, is among the most frequently used biomarkers for breast cancer. Normally, CA 15-3 levels in the blood are low, but they may rise in individuals with breast cancer. However, CA 15-3 is not specific to breast cancer, as elevated levels can also be associated with other types of cancer.

CEA, an oncofetal antigen, can be elevated in various cancers, including breast cancer. Although CEA does not have high sensitivity or specificity, it plays a role in tracking treatment responses and detecting recurrences in breast cancer patients.

CA 125, primarily associated with ovarian cancer, is another glycoprotein that may be elevated in some breast cancer patients, making it a supplementary diagnostic biomarker for breast cancer.

It's important to recognize that these biomarkers are not sufficient for diagnosing breast cancer on their own due to their limited sensitivity and specificity. Physicians typically consider a combination of clinical signs, imaging studies, and other lab results for a comprehensive assessment. Should any breast abnormalities be detected, prompt medical attention is advised, followed by further examination and treatment under a doctor's supervision.
