Symptoms rarely occur at an early stage
Prostate cancer usually grows very slowly, is hardly noticeable during the early stages and there are no early symtpoms to indicate a malignant tumor.
Complaints such as urinary problems usually only occur when the tumor has become so large that it constricts the urethra, which passes through the prostate gland, or when metastases have already developed outside the gland, in the lymph nodes and bones, for example. Unfortunately, many men with an advanced stage tumor only become aware of it due to pains in their bones.
Not every urinary complaint is, however, the result of prostate cancer - a urinary tract infection or a benign enlargement of the prostate - medical term "benign prostate hyperplasia" or BPH - can be the cause. The patient should at all events consult his urologist. Typical symptoms of an enlarged prostate gland are frequent urination, especially at night, post-urinary drip and impotence.
A benign tumor normally develops within the prostate gland, around the urethra. A malignant tumor usually develops in the peripheral zone of the prostate.
