What causes cancer of the testis?
At this time, scientists do not know exactly what causes testicular cancer. We do know that testicular cancer occurs more often in men with certain medical conditions, including undescended testis. Research also indicates that men in white collar or professional occupations are at higher risk for testicular cancer, suggesting that socioeconomic status or lifestyle may be linked to risk factors for this cancer. Employment in the military, aviation equipment support, crude petroleum and natural gas extraction, printing and leather finishing industries has been associated with cancer of the testis. Occupational exposure to polycyclic aromatic hydrocarbons, solvents and dyes, metals, metal dust and possibly cutting oils may be associated with testicular cancer.
