CA is a blood test used to watch certain types of cancer. CA is the name of an antigen. An antigen is a substance that stimulates your body's defense system.
Background: Evidence for the prognostic value of circulating tumor cells CTCs in early-stage breast cancer is swiftly increasing. An alternative approach for identifying patients at risk for recurrence is based on the detection of the mucin-1 MUC1 -based tumor marker CA Here we report the association of these two prognostic markers before and immediately after chemotherapy CHTas well as after 2 and 5 years of follow-up.
The Ca blood test has a "normal" level below Is it possible for the level to reach zero in a person who had invasive cancer with no lymph node involvement? Suzanne M.
Sign in Sign up. A review of tumor markers currently used in cancer care and a summary of antibodies against these tumor markers based on the over 60, formal publications in Labome's Validated Antibody Database. Breast cancer. Assess the risk of tumor recurrence.
Skip to Content. Tumor markers, also called serum markers or biomarkers, are substances found at higher than normal levels in the blood, urine, or body tissues of some people with cancer. In specific situations, biomarker tests can be used for many reasons, including to screen healthy people who have no symptoms of cancer, help diagnose several different types of cancer, determine the prognosis for a person with cancer, monitor how well cancer treatment is working, and watch for a recurrence cancer that has come back after treatment.
Background: A new, fully automated method that measures the breast cancer-associated glycoprotein CA The aim of the present study was to compare this CA Methods: The study was performed retrospectively on preoperative serum samples collected from patients with untreated primary breast cancer node positive and node negative.
Author information: 1 CHI St. Solid tumors involving glandular organs express mucin glycoprotein that is eventually shed into the circulation. As a result, these proteins can easily be measured in the serum and be used as potential tumor markers.
The cancer antigen An antigen is a proteins on the surface of a cell that serves as its unique identifier. CA These markers tend to increase whenever cancer is present.

Nevertheless, tumor marker determination may complement patient staging: high levels in patients thought to have localized disease suggest the presence of unsuspected metastatic disease. Simultaneous measurement of both markers results in increased sensitivity i. The impact of this lead time information on patient outcome is not clear.
