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.

The cause of prostate cancer has not been identified, may be genetic, environmental, and the sex hormones. Prostate androgen secretion by the testis nine ketone conditioning, gonadotropin luteinizing hormone indirect role to play. Juvenile emasculated never occurred to prostate cancer.

Prostate cancer is 98% adenocarcinoma, often from prostate shrinkage of the peripheral part of a majority of more lesions. The transfer of the disease have three ways: 1 to nearby or adjacent organ invasion organizations, and both sides of the first transgression, pierced envelope to vasectomy ampulla, spermatheca, bladder neck and urethra policies; ② lymph node metastasis may fall to para-aortic lymph node and beyond; ③ blood is the most common bone metastasis and poor, spine , femur. Severe pain. , Pathologic fractures can occur. Also transferred to the liver, lung, pleura, adrenal gland, brain and other organs.

Prostate cancer gene from the loss, it is pathological in Shanxi Tumor Hospital director Wang Hung-wide applications such as microdissection, from the level of gene detection of prostate cancer origin concluded.

Prostate cancer in cancer mortality in men, lung cancer has been beyond the second one. Because the disease is a combination of multiple genes changed tumor, pathological changes and the clinical performance of a variety show, according to morphology and cell carcinoma lesions of the reasons for the judgment of the traditional methods highly inaccurate, often leads to the treatment of the blind, affecting prognosis.

Many organ and systemic tumor can be a similar situation occurred, prostate can be benign and malignant. Cancer is cancer and sarcoma, a benign tumor of smooth muscle fiber and fibroids. One prostate sarcoma, leiomyoma, fiber fibroids, the incidence of very low.

Prostate cancer is more common in older male malignancy in Europe and the United States a high incidence of countries, the Nordic countries the incidence of prostate cancer for men, a cancer of the United States ranked second. In China the incidence of prostate cancer will be much lower, but in recent years there have been an increasing trend.

A recent medical study found that a daily diet containing large caloric people, regardless of their eating what kind of food, regardless of their level of body weight, are more vulnerable to prostate cancer.

Medical research on the age of 444 middle-aged and older men for investigation of the diet. The study found that those with high caloric intake have a lower risk of prostate cancer than other possibilities caloric intake of less than nearly four times. In these subjects, 46 men in the survey ago was diagnosed with prostate cancer, while 22 of them are to participate in the study were found to suffer from prostate cancer. The researchers said their findings confirmed the dietary habits and high fever card high incidence of prostate cancer associated theory.

Low income families, was born in the rural areas, smoking, alcohol, divorce (widowed), regular milk, eggs and eat pork, residents of China is suffering from prostate cancer risk factors and eat more green vegetables, fruits and legumes food is important protective factors; Residents of China on prostate cancer prevention should adopt a diet consisting mainly of behavioral intervention and comprehensive measures. This is the Tongji Medical College of Huazhong University of Science and Technology Department of Epidemiology Professor Shi Lu, a recently completed research projects concluded.
