General Information About Penile Cancer

Penile cancer is a disease in which malignant (cancer) cells form in the tissues of the penis.

The penis is a rod-shaped male reproductive organ that passes sperm and urine from the body. It contains two types of erectile tissue (spongy tissue with blood vessels that fill with blood to make an erection):


Corpora cavernosa: The two columns of erectile tissue that form most of the penis.
Corpus spongiosum: The single column of erectile tissue that forms a small portion of the penis. The corpus spongiosum surrounds the urethra (the tube through which urine and sperm pass from the body).

The erectile tissue is wrapped in connective tissue and covered with skin. The glans (head of the penis) is covered with loose skin called the foreskin.



Human papillomavirus infection may increase the risk of developing penile cancer.

Anything that increases your chance of getting a disease is called a risk factor.

Circumcision may help prevent infection with the human papillomavirus (HPV). A circumcision is an operation in which the doctor removes part or all of the foreskin from the penis. Many boys are circumcised shortly after birth. Men who were not circumcised at birth may have a higher risk of developing penile cancer.

Other risk factors for penile cancer include the following:


Being age 60 or older.
Having phimosis (a condition in which the foreskin of the penis cannot be pulled back over the glans).
Having poor personal hygiene.
Having many sexual partners.
Using tobacco products.



Possible signs of penile cancer include sores, discharge, and bleeding.

These and other symptoms may be caused by penile cancer. Other conditions may cause the same symptoms. A doctor should be consulted if any of the following problems occur:


Redness, irritation, or a sore on the penis.
A lump on the penis.



Tests that examine the penis are used to detect (find) and diagnose penile cancer.

The following tests and procedures may be used:


Physical exam and history: An exam of the body to check general signs of health, including checking the penis for signs of disease, such as lumps or anything else that seems unusual. A history of the patient’s health habits and past illnesses and treatments will also be taken.
Biopsy: The removal of cells or tissues so they can be viewed under a microscope by a pathologist to check for signs of cancer.



Certain factors affect prognosis (chance of recovery) and treatment options.

The prognosis (chance of recovery) and treatment options depend on the following:


The stage of the cancer.
The location and size of the tumor.
Whether the cancer has just been diagnosed or has recurred (come back).




Stages of Penile Cancer

After penile cancer has been diagnosed, tests are done to find out if cancer cells have spread within the penis or to other parts of the body.

The process used to find out if cancer has spread within the penis or to other parts of the body is called staging. The information gathered from the staging process determines the stage of the disease. It is important to know the stage in order to plan treatment. The following tests and procedures may be used in the staging process:


CT scan (CAT scan): A procedure that makes a series of detailed pictures of areas inside the body, taken from different angles. The pictures are made by a computer linked to an x-ray machine. A dye may be injected into a vein or swallowed to help the organs or tissues show up more clearly. This procedure is also called computed tomography, computerized tomography, or computerized axial tomography.
MRI (magnetic resonance imaging): A procedure that uses a magnet, radio waves, and a computer to make a series of detailed pictures of areas inside the body. A substance called gadolinium is injected into a vein. The gadolinium collects around the cancer cells so they show up brighter in the picture. This procedure is also called nuclear magnetic resonance imaging (NMRI).
Ultrasound exam: A procedure in which high-energy sound waves (ultrasound) are bounced off internal tissues or organs and make echoes. The echoes form a picture of body tissues called a sonogram.
