(HealthDayNews) -- Testicular cancer, which usually strikes men ages 15 to 34, is one of the most common tumors seen in men under age 40, according to Seton Hall University in New Jersey.

All men in this age group should conduct monthly self-exams, especially those who may be more prone to testicular cancer.

The following factors may increase your risk:

• You are a white male between the ages of 15 and 40.
• You have undescended or late-descended testes.
• There is a family history of testicular cancer.
• You've been diagnosed with inguinal hernia.
