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 it is 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 indicate the occurrence of metastases (spread of disease). 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.
