Prostate Cancer
Content Source: Centers for Disease Control and Prevention
Cancer is a disease in which abnormal cells in the body grow out of control. Cancers are usually named after the part of the body where the abnormal cell growth begins. Prostate cancers are cancer cells from the prostate. When prostate cancer cells spread to other parts of the body, they are called metastases.
What Is the Prostate?
The prostate is a part of the male reproductive system, which includes the penis, prostate, and testicles. The prostate is located just below the bladder and in front of the rectum. It is about the size of a walnut and surrounds the urethra (the tube that empties urine from the bladder). The job of the prostate is to produce fluid that makes up a part of semen. As a man ages, the prostate tends to increase in size. This can cause the urethra to narrow and decrease urine flow.

Symptoms
Different people have different symptoms for prostate cancer. Some men do not have symptoms at all.
Some symptoms of prostate cancer are—
- Difficulty starting urination.
- Weak or interrupted flow of urine.
- Frequent urination, especially at night.
- Difficulty emptying the bladder completely.
- Pain or burning during urination.
- Blood in the urine or semen.
- Pain in the back, hips, or pelvis that doesn't go away.

If you have any symptoms that worry you, be sure to see your doctor right away. Keep in mind that these symptoms may be caused by conditions other than prostate cancer.
