Early Testicle Problem Increases Cancer Risk

Boys whose testicles do not come down into the scrotum are 3 times more likely to have testicular cancer later in life. Before birth, the testicles are formed inside the body. Shortly before birth, they normally move down into the scrotum. In 3% to 4% of full-term boys and about 33% of premature boys, this does not happen. One or both testicles remain in the body. This is called cryptoorchidism. Researchers looked at 12 published studies of cryptoorchidism and testicular cancer risk. The studies included a total of more than 2 million boys. The research showed an increased risk for testicular cancer. The study was published in the Archives of Disease in Childhood. HealthDay News wrote about it November 29.
