Cancer Antigen 125 (CA-125)Cancer Antigen 125 (CA-125)What To Think About- The cancer antigen 125 (CA-125) test cannot
tell the difference between a cancerous (malignant) or noncancerous (benign)
ovarian lump.
- The test for CA-125 may also be done on body fluids
(other than blood) taken from the chest or stomach area.
- High
values of CA-125 in a woman who has been treated for ovarian cancer may mean
that the cancer has returned. Often the high CA-125 level is found many months
before the return of cancer can be found in another way.
- Studies
are being done to see if CA-125 can be used as a screening test for ovarian
cancer. So far, there is not enough proof to show that this test works to find
ovarian cancer early.
