Can Cervical Cancer be detected on an Ultra Sound?

In the early stages of cervical cancer, the ultrasound would look normal. That's why they use a pap smear rather than an ultrasound to check for cervical cancer. By the time the tumors have gotten big enough to show up on ultrasound, the cancer has spread and may not be curable. But if it is detected when it is just on the cervix and very small, then it is usually curable.
