  1. Testicular cancer is the most common cancer in men between the ages of 35 and 39, and the second most common malignancy in males 15 to 35.

  4. Lower levels of exercise, common in professional and white-collar occupation, have been linked to an increased risk of testicular cancer.
  5. Germinal tumors arise from sperm-forming, or germ cells, which account for about 95% of testicular cancers.
  6. About 80 percent of germinal tumors are categorized as seminomas. Several other types of germinal tumors are referred to collectively as non-seminomas.
  7. Spermatocytic seminoma is more aggressive and is more likely to metastasize to other parts of the body; the rate of metastasis for anaplastic seminoma is low.
  8. Testicular cancers tend to spread through the spermatic cord and associated blood and lymph vessels into local lymph glands called the retroperitoneal lymph nodes.
  9. About 40 percent of men with testicular cancer have a history of cryptorchidism, which is the failure of one or both testicles to descend from the pelvis.
