What is the CA 15.3 test?

CA 15.3 is known as tumor marker, which is a substance that cancer cells produce in response to cancer. Therefore, if there is a presence of breast cancer, the CA 15.3 level will begin to increase. The CA 15.3 test is done to analyze the levels of CA 15.3 protein in the bloodstream.

This particular test is mainly used to determine the usefulness of cancer treatment, and to detect if there are chances of recurrence of the cancer.

A relatively high level of CA 15.3 may indicate an advanced stage of breast cancer, including metastatic breast cancer where the liver and bones are also involved. High levels of this protein may have different interpretations depending on your condition. An elevated level may indicate that:

  • the cancer is spreading to the other blood parts
  • your cancer treatment is not working
  • cancer is reappearing

Also remember, the Ca 15.3 level can be very high during the first four to six weeks of new cancer treatment. On the other side, decreasing or low levels of Ca 15.3 may indicate that the treatment is working.

However, a person with breast cancer may also have a low to normal Ca 15.3 level as some types of breast cancer do not produce this protein, or the level may not be high enough to get detected.
