What are the symptoms of prostate cancer

The risk factors for prostate cancer are not fully understood, but some of them are recognized. One of the most important factors is heredity. If a first-degree relative (brother or father) has prostate cancer, the risk of developing prostate cancer will increase by more than 1 times. If 2 or more first-degree relatives have prostate cancer, the relative risk will increase. So what are the symptoms of prostate cancer?

1. Difficulty in urination: The characteristics are slow urination, weak urine ejection, dripping urine, wetting pants and shoes, making it inconvenient for patients to urinate upright and they have to squat, and then they have to urinate in segments, that is, when holding the breath and trying to urinate, they can only urinate with difficulty, and the urine flow is interrupted after a short break.
2. Frequent urination and urgency: In the early stage of the disease, the frequency of urination often increases, especially at night, which attracts the patient's attention. This is mainly caused by congestion and edema of the bladder neck and residual urine, which leads to a decrease in bladder capacity. When there is inflammation of the prostate or stones, there will be urgency and pain in urination.
3. Hematuria: Gross hematuria is uncommon. In a few cases, due to obstruction of the bladder neck and blocked venous return, varicose veins occur in the bladder, leading to the formation of "bladder hemorrhoids". Sometimes blood vessels rupture and produce massive bleeding. If there is concurrent stone formation or tumor occurrence, gross hematuria is also inevitable.
