Prostate swelling may be related to prostatitis, prostate hyperplasia, prostate cancer and other causes, which need to be further differential diagnosis by the doctor. 1. Prostatitis: Prostatitis is a prostate disease caused by a variety of complex causes, with urethral irritation symptoms and chronic pelvic pain as the main clinical manifestations. There are different types, which can be characterized by chills, fever, urinary frequency, urinary urgency, etc. It can also cause swelling of the prostate gland. 2. Prostatic hyperplasia: the main symptoms include frequent urination, urinary urgency, urinary incontinence, increased nocturia, hesitancy in urination, difficulty in urination and intermittent urination, etc., which can also be manifested as enlargement of the prostate gland. 3. Prostate cancer: the enlarged prostate gland compresses the urethra, which can cause progressive urination difficulty, manifested as thin urine line, short range, slow urine flow, interrupted urine flow, dribbling after urination, incomplete urination, and laborious urination, etc. When the tumor volume grows continuously, it can manifest as swelling of the prostate gland. It is recommended that people with swollen prostate go to regular hospitals in time to clarify the cause, and if treatment is needed, standardize the treatment under the guidance of the doctor, so as not to bring adverse effects to the body due to the delayed condition.
