There are no typical symptoms indicating in the early stages a malignant tumor of the prostate. Initially, patients do not notice anything. Complaints appear mainly when the tumor becomes so large that it affects the urethra, passing through the prostate a little further, or daughter tumors (metastases) form outside the prostate, for example, in the lymph nodes and bones.
The following symptoms may occur:
- Increased urge to urinate, especially at night
- Difficulty starting to urinate
- Inability to urinate (urinary retention)
- Weak or intermittent jet
- painful ejaculation
- Blood in urine or semen
- Pain in the prostate
- Severe pain in the lower back (sacrum), pelvis, hips, thighs (sciatica pain)
- Decreased erection strength or impotence.
- Decreased amount of seminal fluid
Often the same symptoms are signs of benign prostate enlargement. But in about 10% cases, prostate cancer is behind them. Treatment of prostate cancer in Germany, detected at an early stage of development, is the most effective.
