Factors that increase the risk of a scrotal mass vary because of the various causes of scrotal abnormalities. Significant risk factors include:

Undescended or retractile testicle

An undescended testicle doesn't leave the abdomen and enter the scrotum during fetal development or early infancy. A retractile testicle descends into the scrotum, but retreats to the abdomen. Either might  increase the risk of:

  • Inguinal hernia
  • Testicular torsion
  • Testicular cancer

Abnormalities present at birth

Abnormalities of the testicles, penis or kidneys present at birth (congenital) might increase the risk of a scrotal mass and testicular cancer later in life.

History of testicular cancer

If you have had cancer in one testicle, you're at increased risk of cancer affecting the other testicle. Having a father or brother who has had testicular cancer also increases your risk.
