An ultrasound is a form of imaging that sends high-frequency sound waves through the body to create images known as sonograms. Doctors frequently use ultrasounds to detect tumors that don’t show up well on X-rays. If you’re preparing for a cancer screening, here’s more information to help you understand what to expect.

What Might an Ultrasound Detect?

As the doctor passes the transducer over your skin, the wand’s sound waves bounce off the organs and tissues. This creates echoes that show the doctor images of the underlying structures and blood flow, allowing them to capture images that diagnose soft-tissue diseases. Abnormal blood flow is often a sign of a tumor, and can determine if existing cancer has spread.

While imaging can’t determine if a tumor is cancerous, it can dictate the next steps. For instance, fluid-filled cysts and solid tumors emit unique echo patterns. While liquid-filled cysts are almost always benign, ones that contain solid parts require further testing.

What Can You Expect From the Procedure?

Usually, no preparation is needed before an ultrasound. However, depending on what is being viewed, your physician may ask you not to eat or drink for up to 12 hours before the appointment. They might also require you to take a laxative or use an enema to provide a clearer image of the site.

Typically, the procedure lasts 20 to 30 minutes. You may be asked to wear a gown before lying down on a table. The specialist will maneuver you into the best position, then apply a water-based gel on the transducer and move it firmly over the area being checked. You can return to your usual activities immediately afterward, and might be asked back for future tests or biopsies depending on the results.
