About Prostate Cancer

Prostate cancer is the most widely diagnosed cancer in American men. In 2012, the American Cancer Society estimates 241,740 new cases of prostate cancer will be diagnosed in the U.S.

More than 90 percent of prostate cancers are found before the cancer has spread outside the prostate, or before it has spread very far.

  • If your prostate cancer is found at this stage, the chance of surviving five years or longer is 99 percent.
  • In the past 20 years, the chances of living five years or longer after a prostate cancer diagnosis have increased from 67 percent to 99 percent.

Signs and Symptoms of Prostate Cancer

There are usually no specific signs or symptoms of early prostate cancer. The following are the most common symptoms of prostate cancer; however, each individual may experience symptoms differently. Signs and symptoms of prostate cancer may include:

  • Weak or interrupted flow of urine
  • Urinating often (especially at night)
  • Difficulty urinating or holding back urine
  • Inability to urinate
  • Pain or burning when urinating
  • Blood in the urine or semen
  • Nagging pain in the back, hips, or pelvis
  • Painful ejaculation


Risk Factors for Prostate Cancer

In general, all men are at risk for prostate cancer; however, there are specific risk factors that increase the likelihood that certain men will develop the disease. Prostate cancer can be caused by a variety of risk factors that include:

  • Age
  • Race
  • Diet
  • Obesity
  • Environmental exposures
  • Having a vasectomy, BPH (benign prostatic hyperplasia), or STD (sexually transmitted disease)
  • Family history of prostate cancer
  • Genetics
