can a blood test detect breast cancer

Release time ：Nov-14,2024

Blood tests can assist in detecting breast cancer to a certain degree, yet their accuracy is not absolute. Typically, these tests can identify tumor markers associated with breast cancer, including CA 15-3 and CEA. However, levels of these markers can also rise due to other causes, so blood tests alone should not be the sole basis for confirming a breast cancer diagnosis.

In clinical practice, physicians often use blood tests in conjunction with other diagnostic techniques, such as mammography, ultrasonography, magnetic resonance imaging (MRI), and biopsy. These combined methods enable doctors to more accurately determine whether a patient has breast cancer and to specify the type and stage of the disease.

For individuals with a family history of breast cancer or other risk factors, regular screening is crucial. Should any symptoms suggestive of breast cancer emerge, such as breast lumps, dimpling of the skin, or nipple discharge, it is imperative to consult a healthcare professional promptly for evaluation and treatment. Keep in mind that early detection and treatment significantly improve the success rate of battling breast cancer, so do not disregard any potential warning signs.
