Prostate cancer is more to see older men, cancer, high incidence rates in the United States and Europe, the Nordic countries the incidence of prostate cancer in men, cancer accounted for the first one, the United States is ranked second. In our country the incidence of prostate cancer is much lower, however, a gradual increasing trend in recent years.
The cause of prostate cancer incidence is not entirely clear, but with the race, genetic factors, environmental factors and sex hormone levels related to the incidence of different ethnic groups can be quite bad prime minister; the yellow race of people have emigrated to Europe and the United States the incidence rate increased; and After castration prostate cancer, and so people do not think the facts demonstrate. In addition, daily life and work, whether it also has prostate cancer predisposing factors? Currently considered that several factors may be related to prostate ulcer related to:
(1) The specific types of chemical carcinogens, or from environmental pollution, ho, benzene and other chemicals are carcinogenic effect; smokers inhale tar and other chemicals can cause cancer, our data show that heavy smokers who die from prostate cancer 1.4 times higher than non-smokers.
(2) The infection of the prostate analysis of 30 years, the Danish scholar has died of prostate cancer incidence curve and the curve of gonorrhea and found that the two are very similar. A group of scholars in the United States retrospective study also found that the incidence of prostate cancer and gonorrhea a clear link between. Some experiments are prompted to do certain virus-infected tissue culture of rat prostate fluid injected into the same kinds of rats, the infected cells can develop into a tumor. Thus raised the cause of prostate cancer and viral infections, sexually transmitted diseases and chronic prostate infection.
In addition, factors such as high-fat diet and obesity may also be incentives for prostate cancer.
At present, the medical profession although not yet fully understand the cause of prostate cancer, but in daily life to avoid these triggers is still possible, each of the elderly should be consciously aware of.
