PROSTATE CANCER

Prostate cancer is the male reproductive system common malignancy. Prostate below the bladder in a chestnut-shaped gland, in the middle through the urethra. It is the secretion of sperm liquid nutrient solution is a component of semen. Benign prostate enlargement and prostatitis produce similar symptoms and cancer. Prostate cancer mainly primary site for posterior subcapsular gland, was latent slow growth, a tumor hours without any clinical manifestation. Thus the advanced prostate cancer generally only show symptoms. A clinical disease duration and often asymptomatic B, C obstructive symptoms of a period, and D both distant metastasis obstructive symptoms have symptoms.

Lack of prostate cancer symptoms. Early symptoms generally not obvious, as a condition of development and different symptoms. Sometimes prostate cancer symptoms first appeared, not urethral obstruction, but the proliferation of local and metastatic bone symptoms. In 50 years of age and above, there will be the frequency, novel, urine and fine lines, bifurcation, and dysuria. Sometimes hematuria, particularly terminal hematuria. Urine membrane of tumor invasion, there will be incontinence. Rectal involvement in the stool can be thinned and defecation difficult. Lumbosacral bone metastases may occur waist, sacrum and sciatica. The lungs can be transferred to a cough and hemoptysis. When access to advanced disease, can cause loss of appetite, weight loss, anemia and other symptoms of malaise and body symptoms.

Vary the type of tumor. Incubation type of occult are no local symptoms. Local clinical symptoms and benign prostatic hyperplasia similar.

Early asymptomatic. When the cause bladder cancer policies neck and posterior urethral obstruction can cause symptoms, hematuria less, to divert some patients symptoms, manifested as low back pain, sciatica,. It is of unknown origin men of metastatic cancer, prostate cancer should be excluded.

Transgression policies posterior urethra and bladder, urethral stricture inflammatory symptoms of frequency, urgency, novel, hematuria and dysuria.

Patients with chronic consumption of symptoms, weight loss, weakness, anemia.

The incidence of prostate cancer main site for posterior subcapsular gland. Thus the advanced prostate cancer generally only show symptoms. A clinical disease duration and often asymptomatic B, C obstructive symptoms of a period, and D both distant metastasis obstructive symptoms have symptoms. Common symptoms of the following three groups:

(1) obstruction symptoms: Prostate cancer of the bladder neck obstruction and symptoms of benign prostatic hyperplasia almost no difference in performance for the slow flow, urgency, urinary interruption, not urination, frequency, can cause serious drop Lek urination and urinary retention.

Because prostate cancer occurred in the posterior lobe, slow growth, was buried after, the early muscle, once the symptoms are often relatively late. The main performance of advanced prostate cancer for lower urinary tract obstruction, or with hematuria and urinary retention. The most prominent symptom is pain.

(A) voiding dysfunction: 80% of the patients tumor caused by the sexual difficulty urinating, urinary flow fining or partial distortion, or urinary bifurcation, urine-extended frequency, urgency, novel, urine intended not flu, serious drop Lek and the outbreak of urinary retention. Only 3% of patients hematuria.
