To achieve the most favorable results of treatment and good prognosis decisive factor is the diagnosis of the disease in the early stages.For this purpose, it should be considered necessary to provide preventive care with rectal inspection of all men over 45 years once a year.In the early stages, some overtures single or multiple dense nodes in one of the lobes of the prostate, tumor later conglomerate can cover a large part or even the whole gland, going without clear boundaries to the surrounding cage and pelvis.Characterized by dense, almost woody texture tumor.Urine and blood are not pathognomonic for this disease changes.Characteristic should be considered as high blood serum enzyme acid phosphatase, especially pronounced for bone metastases.
One of the most reliable methods of diagnosis of cancer of the prostate is a gland biopsy needle transrectal or perineal accesses.
Differential diagnosis of prostate cancer should be carried out with chronic prostatitis, tuberculosis, stones, adenoma and sclerotic processes in the gland.

Prostate cancer is impervious to radiation therapy, so this kind of treatment is of limited use.Among the various methods of radiotherapy should be preferred supervoltnoy therapy, as well as the introduction of interstitial radium preparations.
Prognosis is poor.The best survival was observed in the group of patients with radical surgery.Approximately 50% of patients after radical prostatectomy have a 5-year survival.Urinary incontinence develops in 5-15% of cases, impotence - in all patients.
