I too do not know what you mean by diagnostic process. When I found my cyst/tumor my doctors went into high gear and got a CA125 test. This test is a tumor marker but it is a very good test to have. You need to encourage your doctor to give you one and then go from there. I am a 18 month survivor and it is important to stay on top of your symptoms. If you don't get the answers you want try another doctor and find you an gynecological oncologist if it turns out to be cancer.
