Answer:
Ultrasound
Step-by-step explanation:
Physicians use ultrasound to detect testicular cancer. In such cases, no radiation is used. The ultrasound gives the inside picture of testis i.e. is there any lump or not. Sometimes a person can check by himself, by noticing any abnormality in his testes like the size of the testis, pain in testis, or formation of any lump. But ultrasound gives a confirmation about cancer.
