Penile canceroccurs when malignant growths form on a man’s penis.
Almost all penile cancers come from skin cells called squamous cells. The growths are usually on the foreskin in uncircumcised men, and on the tip of the penis in circumcised men.
According to the American Cancer Society,penile cancer is rare.It accounts for fewer than 1% of cancers in men in the United States. Every year, doctors diagnose about 2,200 new cases in the U.S., and about 440 men die from it.
What Causes Penile Cancer?
Doctors don’t know the exact cause of penile cancer. Risk factors that make it more likely that you’ll develop the disease include:
- Human papillomavirus (HPV) infection.HPVis a group of related viruses that pass from person to person through unprotected sex or other skin-to-skin contact.
- Tobacco use.Men whosmokehave a higher rate of penile cancer than those who don’t.
- Age.About 80% of men who have penile cancer are over age 55.
- Human immunodeficiency virus (HIV).HIV infection has shown to be associated with penile cancer.
- Having an uncircumcised penis.Infant circumcisioncan lower the rate of penile cancer in adulthood.
- Phimosis.Sometimes the foreskin becomes tight and difficult to retract, a condition known asphimosis. This can make examination of the penis and detection of penile cancer more difficult.
- Poor hygiene. Poor hygiene can lead to chronic inflammation, which has been associated with penile cancer.
