In most cases prostate cancer at first stages courses without symptoms. Complaints appear when growth spreads to other organs and metastasis do appear. Prostate cancer progresses relatively slow and thus at the beginning shows with very few symptoms. In several years symptoms grow.
When cancer courses without symptoms the only way to detect it is PSA test which examines rate of prostate specific antigen in male blood. In this case growth size is not significant or are found only pre-cancerous changes. When growth increases and spreads to urinary tract and bladder, may appear urinary irritation symptoms, such as:
- frequent urination
- difficulties with urination
- incontinence of urine
- sudden micturate urge
Also patient may suffer from symptoms of upper urinary tract blocking:
- widening of ureters and kidneys cavity
- pains in lumbar region
- calculi formation in kidneys
Metastasis in bones cause pains in limbs, but metastasis in spinal cord lead to paresthesia and paralysis. Metastasis in organs cause dysfunctions in them.
Thus, all symptoms of prostate cancer are non-specific, they show dysfunctions of damaged organs. That is why to diagnose prostate cancer men over 50 and those predisposed to cancer must make prostate cancer screening.
