Cause of testicular cancer

An early warning? ... Testicular cancer may lead to brain damage, seizures, memory loss, and dementia long before the cancer is even detected, say scientists at the Memorial Sloan-Kettering Cancer Center in New York. They report that men with testicular cancer and damage to one of the brain's emotional centers had a type of antibody in their blood long before the cancer was known, suggesting that these antibodies could be used to give patients an early warning of the cancer. Though it accounts for only 1 percent of all cancers, testicular cancer is the most common type in men aged 15 to 34. (New England Journal of Medicine, June 1999)
