Urethral Cancer: Patient Education

Cancer Facts

According to the National Cancer Institute:

  • Urethral cancer occurs more often in women than in men.
  • It’s more common in people age 60 and older.

Overview

Urethral cancer is a malignant tumor that begins in the tissues of your urethra, the tube that carries urine from your bladder to outside your body. Urethral cancer is rare.

The Urethra

The urethra is a little different in men than in women.

The urethra in women:

  • Is about 1-1/2 inches long
  • Empties in front of the vagina

The urethra in men:

  • Is about 8 inches long
  • Travels through the prostate gland
  • Opens at the end of the penis

How Urethral Cancer Grows

Urethral cancer often begins in the lining of your urethra. The lining of your urethra is composed of different kinds of cells that in some cases become different kinds of cancers. The different cancers require distinct treatments.

Transitional cell carcinoma

  • In women: develops near the urethral opening
