**Question:** Young's operation of Penile cancer is

A. Circumcision
B. Resection of the penile body
C. Excision of the entire penis
D. Radical prostatectomy

**Correct Answer:** C. Excision of the entire penis

**Core Concept:**

Young's operation, also known as a penectomy, is a surgical procedure performed for the treatment of penile cancer. In this operation, the entire penis is removed, including the shaft, glans, and its surrounding tissues. This is done to ensure complete removal of the tumor and prevent its recurrence, as penile cancer can be aggressive and difficult to treat when advanced.

**Why the Correct Answer is Right:**

Young's operation is chosen as the correct answer because it addresses the primary goal of treating penile cancer: ensuring complete tumor removal. When cancer extends beyond the superficial layers of the penis, preserving the penis with less invasive procedures like circumcision (option A) or resection of penile body (option B) may not be sufficient to eliminate the cancer entirely. In some cases, the cancer may recur, leading to more extensive therapy or potential loss of life.

**Why Each Wrong Option is Incorrect:**

A. Circumcision (option A) is a procedure typically performed for medical or religious reasons and does not address the cancer itself. Circumcision only removes the foreskin, leaving the cancerous tissue intact, which can lead to cancer recurrence.

B. Resection of the penile body (option B) is a more localized procedure that removes a portion of the penile shaft where the cancer may be present. While it can help treat localized cancer, it does not address the possibility of cancer extension to deeper tissues or lymph nodes, which would require more extensive surgery like Young's operation.

C. Radical prostatectomy (option D) is a surgical procedure performed for prostate cancer, not penile cancer. This option is incorrect due to the difference in surgical approach and the risk of unnecessary removal of healthy tissue in the prostatectomy, as compared to the targeted removal of the cancerous penile tissues in Young's operation.

**Clinical Pearl:**

When treating penile cancer, it is essential to consider the stage and extent of the cancer. For penile cancer, Young's operation or penectomy is reserved for advanced or recurrent cases, where complete removal of the penis is necessary to ensure complete tumor eradication and reduce the risk of cancer recurrence. In contrast, less-invasive procedures like circumcision or partial penile resection are suitable for localized penile cancer but may not be sufficient for advanced cases.
