What % of testicular Ca is associated with cryptorchidism –
**Core Concept**
Cryptorchidism, also known as undescended testes, is a congenital condition where one or both testicles fail to descend into the scrotum. This condition is associated with an increased risk of various health problems, including testicular cancer.
**Why the Correct Answer is Right**
Testicular cancer is known to have a significant association with cryptorchidism. Studies have shown that individuals with a history of cryptorchidism have a higher risk of developing testicular cancer, particularly the non-seminomatous type. This increased risk is thought to be due to the abnormal environment within the abdominal cavity, which may promote the development of malignant cells.
**Why Each Wrong Option is Incorrect**
**Option A:** 5% - This is an underestimation of the actual risk associated with cryptorchidism.
**Option B:** 20% - This is still lower than the established risk.
**Option C:** 50% - This is an overestimation of the risk associated with cryptorchidism.
**Clinical Pearl / High-Yield Fact**
It's essential for clinicians to be aware of the increased risk of testicular cancer in individuals with a history of cryptorchidism, and to perform regular testicular self-examinations and ultrasounds to detect any potential malignancies early.
**Correct Answer:** C. 30%
