Final answer:
Yes, cryptorchidism is the primary predisposing factor for the development of testicular cancer, which is more common in young males, particularly of European ancestry, and treatable when detected early.
Step-by-step explanation:
The statement "The primary predisposing factor for the development of testicular cancer is cryptorchidism." is true. Cryptorchidism, a condition where one or both testicles fail to descend into the scrotum, is indeed a significant risk factor for the development of testicular cancer. Testicular cancer primarily affects young individuals, especially those between the ages of 15 and 39, and is more common in males of European ancestry compared to African ancestry. It is a rare but highly treatable form of cancer when detected early. Symptoms may include a lump or swelling in one testis, fluid in the scrotum, and testicular pain or tenderness. Biopsies are important in cases of suspected testicular cancer to confirm diagnosis and guide treatment.
