Prostate cancer is the male reproductive system common malignancy. Our incidence is lower than Europe and the United States, but nearly 20 shows a rising trend. The incidence of prostate cancer in parallel with age, according to statistics, few men under the age of 50; 50-60 years the incidence of prostate cancer 1 / 3; Above the age of about 70 1 / 2; Over the age of 80 accounted for about 3 / 4.
The cause of prostate cancer has not yet entirely clear, and substantial clinical data suggest that the hormone. Probably in estrogen and androgen ratio imbalance, especially androgen changes. Some studies found that sexual activity among high, the higher incidence of prostate cancer and in Gu nine patients after resection rarely; In cirrhotic patients, hepatic estrogen on the ability of inactivated declining estrogen levels rise, the incidence of prostate cancer is not high. In addition, data show that environmental pollution, gonococcal infections, prostate hyperplasia, excessive drinking of coffee and alcohol, also with the occurrence of prostate cancer.
Prostate cancer occurred in the posterior lobe, but also sometimes on both sides of the incidence. Prostate cancer is adenocarcinoma, representing about 97%, while squamous cell carcinoma is rare. In the early stages of prostate cancer may be no symptoms, tumor development of the prostate gland increases grow to a certain size, and the bladder neck obstruction occurred when symptoms. At this time there are frequency, urgency, urinary slow, difficulty urinating, or even symptoms such as urinary retention, a few patients have hematuria or a transfer symptoms. When oppression or violation of the surrounding blood vessels or lymph nodes, could arise lower extremity edema, or bone metastasis occurred back pain, limb paralysis.
Prostate digital rectal examination in the diagnosis of prostate cancer effective way. As the number of cancer occurred in the posterior lobe of the prostate and both sides of the edge, the hard texture of the lesions, nodules touched digital rectal potential energy. Prostate cancer examination showed gland increases, nodular hard, uneven, central sulcus disappear glands fixed, and sometimes invading the wall. If the right of men over the age of 45 do digital rectal examination census, the early detection of prostate cancer and improve the cure rate. If that seized in the discovery of a prostate sclerosis, regardless of their distribution sites, highlighting the gland or not, whether the rules should think of the possibility of disease.
The higher the degree of malignancy of prostate cancer, early local infiltration will be clear and lymph node metastasis and tumor often violated seminal vesicle and bilateral lesions, few violations of the rectum. Along the lymphatic metastasis to the nearby pelvic lymph nodes, then transferred to the asylum, the total skeleton, abdominal aortic adjacent mediastinal lymph nodes, and supraclavicular lymph nodes. Prostate cancer can fool to bone metastasis, the most common is the pelvis, lumbar spine, femur and ribs. Blood Road also can be transferred to the lung, liver, kidney, brain and other organs.
If prostate cancer diagnosis as early detection, treatment can be achieved better results. Common clinical examination: (1) ultrasonic examination. (2) X-ray inspection. (3) radionuclide scan. (4) CT. (5) MRI. (6) prostatic fluid and urine cytology. (7) acid phosphatase (PAP) Determination. (8) prostate specific antigen (PSA) Determination. (9) Syrup protein (r - Sm) Determination. (10) prostate biopsy.
