What to expect from transvaginal ultrasound for womb cancer

You usually lie on an examination bed with your knees bent. The sonographer explains the scan, covers and lubricates a slim probe, then gently places it in the vagina. Images can show the womb lining, womb shape and nearby pelvic structures. The scan does not by itself confirm womb cancer; a clinician may recommend tissue sampling when the images or symptoms need further investigation. You can ask for the examination to pause or stop.

Ask whether you need a full bladder or any other preparation; transvaginal scans commonly use an emptied bladder, but follow the instructions from your centre. Wear clothing that is easy to change and tell the team if you are uncomfortable or have difficulty with internal examinations. Mild pressure or brief cramping may occur. You can generally return to usual activities after the scan. Discuss when and how the report will be shared, especially if you have ongoing bleeding.

The scan itself should not cause significant pain. Contact the service if you develop persistent pain, heavy bleeding, fever or unusual discharge afterwards. Seek urgent care for severe pain, faintness or heavy bleeding. Bleeding after menopause, bleeding between periods or new pelvic pain should be reported even if a scan has been arranged, because the urgency depends on the symptom and your clinical history.

Ask why the scan is recommended, whether the womb lining or ovaries need particular assessment, when results are expected, and whether a biopsy is the next step. Tell the clinician about bleeding patterns, medicines and pregnancy possibility before the examination.
