Late stage of prostate cancer may present with abnormal urination, blood in semen, erectile dysfunction, discomfort in pelvic area, bone pain, bone fracture, pain in lower limbs and other conditions. Prostate cancer is a malignant tumor that occurs in male prostate area, and there is no obvious manifestation in the early stage. As the tumor grows, patients may have lower urinary tract obstruction symptoms, such as slow urine flow, frequent urination, urgency, difficulty in defecation, etc., and even urinary retention or incontinence may occur. If the patient does not receive timely and effective treatment, and the disease develops to the advanced stage, the patient may experience discomfort such as blood in semen, erectile dysfunction, pain in pelvic area, etc. Some of them may be accompanied by weakness, edema, anemia, etc. If bone metastasis occurs, the patient may also experience discomfort such as bone pain, pathologic bone fracture, and compression of spinal cord, etc. The patient may be suspected of having prostate tract obstruction. If the above symptoms occur and prostate cancer is suspected, one should consult a doctor in time, make a clear diagnosis of the disease under the doctor’s guidance and carry out the corresponding treatment, avoiding blind judgment on one’s own, so as to avoid delaying one’s condition.
