One, Pathogenesis
(1) Causes
The cause of prostate cancer has not yet entirely clear, but sex hormone and prostate cancer relationship is clear. Estimates may be circulating estrogen and the hormone imbalance, in particular the male hormone changes. Puberty that will not happen with testicular prostate cancer. Androgen suppression can be dissipated to prostate cancer. In patients with liver cirrhosis, liver Inactivation of estrogen decline, increased levels of estrogen and thus the incidence of prostate cancer is not high. Prostate cancer is infection with environmental pollution and there is a certain relationship. Excessive use of alcohol and coffee also the incidence of prostate cancer increases. At the same time, there are familial prostate cancer incidence trends.

(2) Pathogenesis
Justice of the medicine, stem not evil; The evil Cou, the gas will imaginary. The occurrence of the disease is common inside and outside of the result. The incidence of prostate cancer, no two internal and external aspects, including the invasion of 1,491 tips, diet by injury, mental emotional factors, hurt by the Plaza Visceral dysfunction. The pathology of prostate cancer can be summarized as the following ways.
1. Shenqi weak injured by diet or sexually excessive Shenqi Haoshang, upright inadequate, missing organs dependent on temperature, endocrine dysfunction, lower immune function, blood stasis from malnourishment mass.

2. The daily diet diet injury, lost in the spleen and stomach Yun, qi metaplasia inadequate, or the phlegm damp stopped, gathered under the coke, or the Habitat Office of Environmental Impact, renal loss of gasification Division, which demonstrated voiding dysfunction and pain asthma.

3. Drug evil, evil drug invasion emplacement outside the body, set in the next coke, local qi running impeded, from ancient tumor stasis.
Two, typing
Prostate cancer mainly occurs in men over the age of 50, occasionally occurred in young people, even children. More than 95% of adenocarcinoma, for the remaining transitional cell carcinoma, squamous cell carcinoma and sarcoma. Prostate cancer from the acinar and duct occurred often in the peripheral zone of origin, seldom occurred in the central area. Prostate cancer often multiple lesions, a single nodule only 10%.

Transitional cell carcinoma and squamous cell carcinoma is less than 3%, often from prostate catheter end of the transitional epithelium in coverage, with adenocarcinoma merger. The average age of onset than adenocarcinoma, small 10-year-old, acid phosphatase normal; Right radiation and hormonal therapy without reaction, the rapid growth of a poor prognosis. Sarcoma is common in young people, the rapid growth of the radiation and hormonal therapy no reaction, a very bad prognosis.
Pathologic classification of prostate cancer can be divided into three types:
1. Incubation of tumor small and asymptomatic, without metastasis. Commonly found in the autopsy.
2. Local tumor clinical symptoms have been violated obvious, and the transfer later.
3. Concealment of the primary lesion small and difficult to find, but often the early transfer.
3, dissemination and transfer
Prostate cancer by local infiltration, lymphatic and hematogenous metastasis to any location. Transfer of prostate cancer can occur in any period.
1. Local infiltration of prostate cancer cells through infiltration through the prostate capsule, violations spermatheca, bladder neck, urethra, or both pelvic other pelvic organs.
2. Lymph node metastasis of prostate cancer through the lymphatic system can often transferred to the internal iliac and obturator lymph nodes, but can occur late iliac, iliac, and supraclavicular next aortic lymph node metastases.
3. Revascularization of prostate cancer metastasis of prostate vein from the penis into the deep vein of spinal venous pulse, and arriving pelvis and lumbar. In order pelvis, lumbar spine, thoracic spine and ribs and transfer. At the same time, can occur lung, liver, adrenal and other places transfer.
