Localised or early prostate cancer usually causes no symptoms. However, urinary symptoms occur commonly in men and are usually caused by benign prostate enlargement and are not always related to cancer.

They include:

  • Feeling the frequent or sudden need to urinate
  • Finding it difficult to urinate (for example, trouble starting,
  • or not being able to urinate when the feeling is there)
  • Discomfort when urinating
  • Finding blood in urine or semen
  • Pain in the lower back, upper thighs or hips
  • Bone pain
  • Unexpected weight loss

It is important to remember that these problems might not be symptoms of cancer. An enlarged prostate gland can be caused by benign prostatic hyperplasia (BPH, a non-cancerous enlargement of the prostate gland) and a rise in prostate specific antigen (PSA) can be caused by prostatitis (an infection or inflammation of the prostate).
