It is common to use blood tests to diagnose testicular tumors. Most testicular cancers produce substances that reach the blood and can be detected by blood tests. Such examination should always be performed at the beginning of patient care, and are very important in the diagnosis, quantification of the degree of disease impairment and serve as a parameter for follow-up after treatment. The major substances released into the blood indicating testicular cancer are alpha-fetoprotein (AFP) and human chorionic gonadotropin (GCH).
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.
