What are the symptoms of prostate cancer? How can I detect it in my life? Early stage prostate cancer is usually asymptomatic. When the prostate tumor progresses and invades or obstructs the urethra or bladder neck, symptoms like lower urinary tract obstruction or irritation will occur, such as waiting for urination, straining to urinate, prolonged urination, interruption of urine flow, incomplete urination, urinary frequency and urgency, etc. In severe cases, acute urinary retention, hematuria and urinary incontinence may occur. When bone metastasis occurs in prostate tumor, it can cause bone pain, pathological fracture, anemia, spinal cord compression leading to lower limb paralysis, etc. Of course, it is not necessary for the above symptoms to occur. Of course, it does not necessarily mean that the above symptoms are prostate cancer, but many diseases may have more or less similar symptoms, such as prostate enlargement, prostatitis, bladder urethral infection, neurogenic bladder, bladder stones, bladder tumor, etc. The bone symptoms also need to be distinguished from many orthopedic diseases, so if you have the above symptoms and they get worse quickly within a short period of time (for example, within a few months), you need to be alerted to go to the doctor. Therefore, if you have the above symptoms and they worsen quickly within a short period of time (for example, within a few months), you need to be alert and go to a regular hospital to have a systematic examination by a specialized urologist for a clear diagnosis. As long as any disease can be detected at an early stage, it is generally relatively easy to treat and the efficacy is often better, with a good chance of complete cure.
