Doctors can view testicular cancer through an ultrasound, the standard imaging technique used in identifying the disease, according to the American Cancer Society. Patients experiencing swelling, tenderness or bumps -- the common symptoms of testicular cancer -- often undergo the screening.
The test uses sound waves from a small, handheld instrument to produce images of internal organs. The sound waves echo as they bounce off the organs, and the pattern creates a computer image. Doctors then use the pattern to differentiate benign conditions from solid tumors that may be cancerous. Any solid lumps then receive further testing, as explained by WebMD.
