Deck 28: Epidemiology of Cancer of External Male Genitalia

Question 1

In 2018, 34,475 men were diagnosed with cancer of the penis, and 15,138 deaths were attributed to this malignancy.

Answer 1

True

Question 2

Carcinomas of the penis are rare among men living in developed countries but are relatively common among the male populations of some underdeveloped nations.

Answer 2

True

Question 3

Rates are very low among Israeli Jewish men (0.1 per 100,000) who are circumcised shortly after birth and among Muslim men (0.2 per 100,000) who are circumcised during childhood.

Answer 3

True

Question 4

In contrast, rates are much higher (3 to 10 per 100,000) among men living in certain parts of the world where circumcision is rare.

Question 5

The incidence of carcinoma of the penis increases steadily throughout life, and the rates are highest for elderly men, aged 70 years or older.

Question 6

Infection of the male genitalia by oncogenic strains of human papilloma virus has not been confirmed to play an etiologic role in a subset of cases of penile cancer.

Question 7

There is very little evidence suggesting that neonatal circumcision reduces the risk of carcinoma of the penis.

Question 8

Phimosis refers to circumferential fibrosis of preputial tissue (foreskin) in uncircumcised men that leads to narrowing and inability to retract the penile foreskin over the glans penis.

Question 9

Phimosis in uncircumcised men is a significant risk factor for the development of carcinoma of the penis.

Question 10

Recent reports suggest there may be synergism between HPV and HIV infection in elevating the risk of developing carcinoma of the penis.

A)Copper miners

C) HPV16
D) HPV18

Question 14

Which of the following exposures is not a risk factor for cancer of the scrotum?

A) Agent Orange
B) Coal tar

Question 15

Strategies for the prevention of carcinoma of the penis include all of the following except:

A) circumcision early in life.
