CA 27.29; BREAST CANCER MARKER

CA 27.29 is a tumor marker used to monitor the progression of breast cancer. It is a protein produced by certain breast cancer cells and can be found in the blood. Elevated levels of CA 27.29 may indicate the presence of breast cancer, especially in advanced stages. However, it is important to note that CA 27.29 is not a diagnostic test and can also be elevated in other conditions, such as benign breast disease or ovarian cancer. Therefore, a high CA 27.29 level should be interpreted in conjunction with other clinical factors and additional testing.
