Overview
Common risk factors for testicular seminoma include undescended testis, caucasian race, previous tumor in the contralateral testis, and family history of testicular germ cell tumor.
Risk Factors
Common risk factors for testicular seminoma include:[1][2][3]
- Caucasian race
- Undescended testis
- 10-40x increased risk
- Around 10% of seminoma are associated with undescended testis
- Higher risk if intra-abdominal testis compared with intra-inguinal
- orchidopexy prior to puberty can reduce the tumor risk
- Increased risk in the contralateral normally descended testis
- Previous tumor in contralateral testis
- Family history of testicular germ cell tumor
- 4x increased risk if father affected
- 9x increased risk if brother affected
- Testicular microlithiasis
- 8x increased risk in symptomatic testicle with microlithiasis
- no increased risk found in asymptomatic testicles therefore screening is unlikely to be useful
- Testicular dysgenesis
- Testicular feminization
- Klinefelter syndrome
- Other risk factors
