Prostate Cancer

Symptoms

Prostate cancer usually causes no symptoms in the early stages. As the malignancy spreads, it may constrict the urethra and cause urinary problems.

Urine flows from the kidney through the ureters into the urinary bladder where itis temporarily stored. As the bladder becomes distended with urine, nerve impulses from the bladder signal the brain that it is full which gives the individual the urge to void. By voluntarily relaxing the sphincter muscle around the urethra, the bladder can be emptied of urine. Urine then flows out through the urethra.

Later Stage Urinary Symptoms

Later-stage urinary symptoms typically include:

• Weak urinary stream.
• Inability to urinate.
• Blood in the urine.
• Interruption of urinary stream (stopping and starting).
• Frequent urination (especially at night).
• Pain or burning during urination.

Late Stage General Symptoms

Significant pain in one or more bones may herald the occurrence of metastases. This chronic pain occurs most often in the spine and sometimes flares in the pelvis, the lower back, the hips, or the bones of the upper legs. It may be accompanied by significant weight loss.
