How can an ultrasound help diagnose cancer?

Also called a sonogram, ultrasound works by bouncing high frequency sound waves off tissues in your body to form images. This technology is used to help diagnose cancers in the breast, liver, kidneys, uterus, and ovaries.

It is important to keep in mind that not all cancers can be seen through diagnostic imaging. A tumor may be too small or in a location that’s difficult to see. In these instances, other tests may prove more useful and may part of your diagnosis. In all cases, a biopsy (an examination of cells or living tissue from an area suspected to be cancerous) is the most definitive way to test for the presence of a malignant tumor and to determine what kind of cancer exists. Biopsies can be performed though a number of minimally invasive procedures and are always necessary to confirm a cancer diagnosis.
