Thank you so much for your question. It is my privilege to be able to help.
The blood test was CA-125. I am not sure what "high grade mass" means because that is not typically how ovarian masses are described. However, based on what you wrote, it seems that they saw something on your ovary that was suspicious for cancer. The CA-125 test is a blood test that is usually elevated in women with ovarian cancer
. If that test result is elevated, than the chances of ovarian cancer are significant. If it is not elevated, it is very unlikely that you have ovarian cancer.
Even if the results are elevated, it often turns out to be benign and not cancer, but the chances of cancer are higher.
You need to await the results, and your doctor will help you understand what to do based on what the blood test shows.
I hope this was helpful to you. If you are satisfied please don't forget to ACCEPT the answer. If you have any more questions, please feel free to respond to this question. Good Luck! Dr. SaulJE
