Because prostate cancer is usually so slow growing, it rarely causes physical symptoms until quite advanced. Even then, the typical symptoms are non-specific and easily confused with symptoms from other conditions, which are either not dangerous or less worrisome than prostate cancer.
Urinary Symptoms
Urinary problems, such as an intermittent or weakened stream or increasing frequency, may be due to a prostate tumor. They also could caused by overgrowth of the prostate gland or by a bacterial or viral infection in the urinary system.
Blood in the Urine
Bloody urine can come from many causes including benign enlargement of the prostate, broken blood vessels in the urinary system, kidney or bladder stones or cancer. A doctor should evaluate any occurrence of this.
Blood in Semen
Usually this is not a symptom of a prostate tumor. Rather it can come from irritation of the urinary tract, straining during sexual activity or even from a bowel movement. However, a doctor should check this symptom.
Swelling in the Lower Extremities
If prostate cancer spreads to the nearby lymph nodes, it may cause swelling in the legs.
Pain
A prostate tumor that has entered an advanced stage can cause bone pain in the lower back, hip or pelvis.
