The early stage of prostate cancer does not present typical warning signs in the body, and most of them have no obvious clinical symptoms. Even if patients have discomfort, they often think it is because they are getting older and consider it a normal phenomenon and do not pay attention to it. When the tumor enlarges to a certain extent, it can be confused with prostate enlargement when it compresses the urethra and causes lower urinary tract symptoms. As a result, most of the patients were first found to have metastatic disease and only after further examination was prostate cancer diagnosed. At this time, the disease is advanced and the time for radical treatment is lost, and the prognosis is not good. It can manifest as lower urinary tract obstruction symptoms, such as urinary frequency, urinary urgency, slow urine flow, interruption of urine flow, incomplete urination, and even urinary retention or incontinence. Hematuria is rare. The prostate can also present with local invasive symptoms and distant metastatic symptoms, such as involvement of the cysto-rectal space and distant metastases causing bone pain, spinal cord compression nerve symptoms and pathological fractures.
