What is NOT true about carcinoma penis?
Show Hint
Only circumcision at birth gives strong protection; later circumcision does not carry the same guarantee.
Updated On: Jul 8, 2026
- Circumcision any time before puberty is 100% protective
- Erythroplasia of Queyrat is premalignant
- Occurs in unhygienic conditions
- Presents with inguinal node enlargement in 50% of the cases

The Correct Option is A
Solution and Explanation
Step 1: Recall the risk factors for carcinoma penis.
Carcinoma penis is strongly linked to phimosis, poor hygiene, and the buildup of smegma under the foreskin. It is rare in men circumcised at birth.
Step 2: Understand the true protective effect of circumcision.
Neonatal circumcision, done at birth, removes the foreskin before smegma and chronic irritation can act on the glans, and this gives close to complete protection from carcinoma penis.
Circumcision performed later, even before puberty, does not carry this same near total protection, since some exposure to smegma and chronic irritation may already have occurred by then.
Step 3: Analyze option (A).
The statement claims circumcision at any time before puberty is 100% protective. This is not accurate, since only circumcision done at birth carries near complete protection. Doing it later, though still helpful, does not carry that same guarantee.
So option (A) is the false statement.
Step 4: Analyze option (B).
Erythroplasia of Queyrat is a red, velvety patch on the glans, and it is a recognized premalignant lesion (a form of carcinoma in situ) that can turn into invasive carcinoma penis. This statement is true.
Step 5: Analyze option (C).
Poor hygiene lets smegma collect under the foreskin, and this chronic irritation is a well known risk factor for carcinoma penis. This statement is true.
Step 6: Analyze option (D).
Inguinal lymph nodes are the first site of spread for carcinoma penis, and enlarged inguinal nodes are found in about half of patients at presentation, though not all enlarged nodes mean actual tumor spread since some are just reactive from infection. This statement is true.
Step 7: Final answer.
The false statement is that circumcision any time before puberty is 100% protective, since only circumcision at birth carries that level of protection.
