Clinical found that prostate cancer occurred in the posterior lobe, and no more early symptoms, even some discomfort, would not be enough to cause the patient's attention. When the tumor increased urethral compression, often confused with BPH. The club, about 80% of the patients first discovered lesions distant metastasis, and then found that prostate cancer. At this time, advanced lesions have a poor prognosis. Thus, the early detection of prostate cancer is clearly important.

Prostate cancer clinical symptoms arise sooner or later and the extent of tumor growth depends on the speed and extent of urethral compression. Surrounded by transurethral prostatectomy, it first oppression urethral carcinoma, demonstrated abnormal voiding symptoms.
