How accurate is the CA125 test in diagnosing ovarian cancer?

Postby armaan83 » Sun Apr 03, 2011 11:43 am

Does any one know how accurate this test is in the diagnosis of ovarian cancer. I have a number of thick walled ovarian cysts on both ovaries, the largest being 6.5 cm x 5.5cm. Firstly I was told that is not cancer as the test came back low. I was then told it is highly unlikely to be cancer and then I was told no test is 100% so we won't know until the ovaries and cysts are removed. I was discharged from hospital and told that I would have a repeat scan in 2 weeks and see the oncologist the same day and have the operation within 12 weeks. Today I have had an appointment come thorough to see the oncologist at the end of January and no mention of the scan. I am terrified as my mother died of ovarian cancer. I am now thinking of making a private appointment to see the oncologist just for peace of mind.

The CA125 test is used as an indicator of the POSSIBLE presence of ovarian cancer, it's main use is in follow up to see if there is a return. The diagnosis has to be made by other means as well as the test, such as biopsy or scan. Not doing a follow up appointment till January seems to suggest there is no urgency. BUT to set your mind at rest I would suggest contacting the oncologist and asking to see him/her just to allieve you worries.

CA-125 is a tumor marker and it is not intended to diagnose cancer at all. It is used to monitor treatment. It really does no good to see an oncologist unless you have been diagnosed with cancer and after your surgery as there is little they can do for you until then. They treat cancer and rarely diagnose it.
