What are the common symptoms of prostate cancer? How to detect prostate cancer early?

Prostate cancer is extremely harmful to men and seriously affects the health of patients. So, what are the common symptoms of prostate cancer? Let's take a look at the experts' explanation of this issue.

(1) Obstructive symptoms: The symptoms of prostate cancer are almost the same as those of benign prostatic hyperplasia, manifested as slow urine flow, urgency, interrupted urine flow, incomplete urination, frequent urination, and in severe cases, dribbling urine and urine retention. There are two clinically significant points in the obstruction process: ① The course of the disease continues to progress, which is different from the slow progression of prostate hyperplasia. ② Hematuria is not common. It is worth noting that the first symptom of prostate cancer is usually not urethral obstruction, but more common symptoms are local spread and bone metastasis. Only in the late stage does the cancer invade the glands around the urethra and cause obstructive symptoms.

(2) Metastatic symptoms: When the tumor invades the capsule and the nearby perineural lymphatic vessels, symptoms of prostate cancer may include perineal pain and sciatica. Bone pain is a common symptom of stage D, which manifests as persistent pain in the lumbosacral region and pelvis, which is more severe when lying in bed; when the rectum is involved, it may manifest as difficulty in defecation or colon obstruction; when prostate cancer invades the membranous urethra, urinary incontinence may occur; other metastatic symptoms include lower limb edema, lymphadenopathy, subcutaneous metastatic nodules, pathological fractures, etc.

(3) Systemic symptoms: Systemic symptoms include weight loss, fatigue, low fever, progressive anemia, cachexia or renal failure.
