What is an ultrasound?
This versatile imaging technology uses high-frequency sound waves to produce images of organs and tissues within the body. By capturing images in real time, ultrasound exams reveal the structure and movement of the body's internal organs, such as the heart, blood vessels, kidneys and liver.
Ultrasound can also be used to precisely locate the position of a tumor in order to guide a biopsy or aspiration procedure. For example, ultrasound may be used to mark out the boundaries of a tumor prior to its removal. It can also be used to administer cancer treatments.
Depending on the body part being examined, some types of ultrasound include: abdominal, breast, cardiac, pelvic, prostate, renal, testicular and thyroid. Unlike X-rays, ultrasound exams do not use radiation.
Ultrasound for testicular cancer
Also known as sonography, this non-invasive procedure uses the reflected echoes of high-frequency sound waves to produce images of internal organs. This can help doctors determine if a lump is solid, or filled with fluid. Because malignant tumors often produce a pattern that is different from normal testicular tissues, this test can help doctors determine if a lump is suspicious, and if further tests should be performed.
