CA 27-29 (pronounced: see-ay twenty-seven to twenty-nine), also known as Cancer Antigen 27-29 or Carbohydrate Antigen 27-29, is a tumor marker used in monitoring breast cancer patients. It is a glycoprotein produced by certain types of cancer cells, including breast cancer cells.
Etymology
The term "CA 27-29" is an abbreviation for "Cancer Antigen 27-29". The numbers 27-29 were assigned sequentially as these antigens were discovered. The term "antigen" refers to a substance that triggers an immune response, in this case, it is produced by cancer cells.
Usage
CA 27-29 is primarily used to monitor response to breast cancer treatment and to check for breast cancer recurrence. It is not used for screening or diagnosing breast cancer because it can also be elevated in other conditions and in some healthy people.
