I agree. The trans-vag ultra-sound is the way to go. The CA125 may be helpful, too.
I wish her the best of results. Marie
Please encourage her to have the transvaginal ultrasound and have prompt follow-up. Ovarian cancer can be cured when it is caught early. The size of her mass is small, so if could be very early in the disease process or it could be entirely benign. I am guessing she is post-menopausal. That slightly increases her chances of it being a malignancy. The transvaginal ultrasound will tell her more about her cyst. If it is complex, I would urge her to get it surgically removed. The only way to know for sure if a mass is malignant is to have it surgically removed and biopsied. Usually, in pre-menopausal women, doctors wait until a complex mass reaches 5cm or larger before recommending surgery. But, in older women the recommendation depends on the individual doctor. I had a neighbor who was in her sixties and had a 8cm complex ovarian mass removed and it turned out to be benign. The odds are in her favor, but it is better to be safe than sorry. Ask the doctor to run a CA-125 test on your mom and if her mass is complex, she should be referred to a gynecologic oncologist prior to surgery. I hope all turns out to be benign!
