Prostate cancer usually doesn't produce any noticeable symptoms in its early stages, so many cases of prostate cancer aren't detected until the cancer has spread beyond the prostate. For most men, prostate cancer is first detected during a routine screening such as a prostate-specific antigen (PSA) test or a digital rectal exam (DRE).
When signs and symptoms do occur, they depend on how advanced the cancer is and how far the cancer has spread.
Less than 5 percent of cases of prostate cancer have urinary problems as the initial symptom. These problems are caused when the prostate tumour presses on the bladder or on the tube that carries urine from the bladder (urethra). However, urinary symptoms are much more commonly caused by benign prostate problems, such as an enlarged prostate (benign prostatic hyperplasia) or prostate infections.
When urinary signs and symptoms do occur, they can include:
- Trouble urinating
- Starting and stopping while urinating
- Decreased force in the stream of urine
Cancer in your prostate or the area around the prostate can cause:
- Blood in your urine
- Blood in your semen
Prostate cancer that has spread to the lymph nodes in your pelvis may cause:
- Swelling in your legs
- Discomfort in the pelvic area
Advanced prostate cancer that has spread to your bones can cause:
- Bone pain that doesn't go away
- Bone fractures
- Compression of the spine
