Testicular ultrasound is usually done to
check a mass or pain in the testicles for cancer. Young men with a
testicular mass or pain should be checked right away by a doctor. Testicular

A mass that does not have fluid, has fluid with tiny
floating pieces (atypical cyst), or is larger than expected needs more testing. Often a follow-up ultrasound is done in 6 to 8 weeks. This is to

an atypical cyst is present and a testicular ultrasound can't show
if it is cancer, a
biopsy may be done.
