Understanding Prostate Cancer

You or someone you care about has been diagnosed with prostate cancer. This video will help you understand how prostate cancer affects your body.

Anatomy and Function of the Prostate Gland

The prostate is a gland in men that makes part of the fluid in semen. It's found just under the bladder, in front of the last part of the large intestine, called the rectum.

The prostate wraps around part of the urethra, which is the tube that passes urine and semen out of the body.

How Prostate Cancer Develops

Most prostate cancer starts in tiny sacs within the gland that make prostatic fluid. Here, cancer cells form from gland cells that line the sacs.

Over time, the cancer cells can multiply, and form a malignant, or cancerous, tumor. However, most prostate cancer grows more slowly than other types of cancer.

Symptoms of Prostate Cancer

There are usually no symptoms in early prostate cancer. However, as the tumor enlarges the prostate, you may have the following symptoms:

  • Difficulty starting urination
  • Weak, interrupted, or painful urination
  • Needing to urinate frequently, especially at night
  • Painful ejaculation, problems getting an erection
  • Blood in urine or semen
  • Pain or stiffness in the lower back, hips, or pelvis

Note that these symptoms may be caused by prostate enlargement that is not cancer.

Grading and Staging of Prostate Cancer

If you have prostate cancer, your doctor will need to determine the grade and the stage, or progression, of the disease.

Grading Each grade is based on how normal the prostate tissue looks under a microscope. The grading system for prostate cancer is called the Gleason grading system.

In this system, samples of two main areas of the tumor will each be given a grade from one to five. The grades will be added together to give the cancer a Gleason score between two and ten.

The higher the Gleason score, the more likely the cancer is to grow and spread to other areas.

Staging

Each stage for prostate cancer is based on the amount of cancer you have and where it's found.

Understanding Prostate Cancer Br
  • Stage I: Cancer has not spread outside the prostate.
Understanding Prostate Cancer Br
  • Stage III: Cancer spread to or beyond the edge of prostate.
Understanding Prostate Cancer Br
  • Stage II: Cancer is more advanced, but is still only in the prostate.
Understanding Prostate Cancer Br
  • Stage IV: Cancer spread to nearby and distant tissues.
