What causes "cancer village" form?
"Cancer villages" caused by a number of bereaved families
Dam located in the village group Chajian drift cards Tianchang village south-west of the town, this is not a large group of villagers, a total of 24 people, consisting of 104 people. But in recent years, the cancer epidemic in this village, there have been more than half of the people suffering from family gastric cancer, liver cancer, lung cancer, esophageal cancer, lymphoma and other cancers.
Villagers Weiming Hua is one of them, in mid-April 2011, died of stomach cancer, while her husband and son also died of esophageal cancer in 2006 and 2008, and now daughter had remarried to the field. With villagers saying, "The family does not exist anymore."
"Cancer village" appearance is a testament to the harsh environment of cancer
The 2013 original, haze, dust, groundwater pollution and a series of hot issues, so that "GDP first" concept of development, but also by a new round of gusto. Woe lung water odor, gas, under attack, in February 2013, in the "China cancer village map" drawn by the public interest in environmental organizations microblogging spread, increasingly hostile environment shrouded in the shadow of cancer, deputy director of the Cancer Center of Sun Yat-sen, Professor Fu Jianhua, vice president, said: "'cancer villages' appearance is a testament to the harsh environment of cancer, a large number of epidemiological studies have confirmed the investigation and toxicology, environmental pollution can cause acute human poisoning can also lead to chronic hazards, mutagenic, carcinogenic, teratogenic, reproductive disorders and other long-term effects ...
Eighty percent of cancer are related to the environment
High incidence of cancer folded behind "murderer" directed harsh environments
According to the "2012 Annual Report of Cancer Registration in China," recorded in 2012 the National Cancer mortality was 180.54/10 million, or an average of 100,000 people each year alone, about 180 people die of cancer, this data is compared with 2004 136 people died of cancer; second inquest early 1990s, this data is 108; first inquest mid-1970s, this data is only 74 people. Genetic factors, environmental factors, lifestyle carcinogenic three conditions, the latter is undoubtedly the main reason for the growing number of cancer.
Environmental pollution caused by the high incidence of cancer
Fu Jianhua, vice president, said: "The medical profession believes that the current 80% of the known cancer related to the environment, to soil contamination from air pollution to water pollution, no exaggeration to say that people's living environment is suffering increasingly severe challenges to lung cancer, for example, in addition to smoking, high momentum with China its widespread air pollution are not unrelated.
Cancer patients 1/3 due to environmental pollution carcinogens
In 2007, the World Bank, "China's environmental pollution losses" (Cost of Pollution in China) report clearly states that air pollution, especially air pollution in large cities, is an important cause of lung cancer and other lung diseases increase in incidence. In addition to lung cancer, the report also shows that China's rural areas, such as the digestive system and liver cancer, stomach cancer mortality rates are significantly higher than the world average; mainstream view of the medical profession, the incentives and insecurity digestive cancers, dirty drinking about ...
Environmental carcinogens hidden behind the "cancer scare" is spreading
Experts said that the face of cancer also need to feel insecure
In these pollution factors, chemical pollution accounted for a large proportion. Compared with visible pollution, 'environmental management of chemicals and risk-based information bottom countless' facts even more gripping. Alkylphenols, phthalic acid esters from dioxins and plastics and food packaging materials, most environmental hazardous chemicals unclear, quantity and pollution emissions of toxic and hazardous chemical contaminants unclear ...... many 'unclear 'Let the people living in them will have a sense of panic. The most immediate concern is the 'cancer scare'.
The incidence of cancer is a complex process involved in a multi-factor
Fu Jianhua, vice president, said, "The recent haze, dust storms, the emergence of cancer villages, so many people are concerned about cancer, or even about whether you will therefore cancer, in fact, modern medical studies have shown that the incidence of cancer is more than one factor involved in , multi-channel, complex multi-step process, is the result of environmental factors and genetic factors working together. cancer caused by environmental factors alone rarely, and they are to be acquired and genetic susceptibility to the common occurrence of cancer from to positive effect.
Fuyuan Chang continued, for example: "The lung cancer, for example, the medical profession and the study found that the incidence of lung cancer in vivo AHH about, once this enzyme in vivo and more people smoking easily induced lung cancer, plus in height atmospheric pollution, the probability of occurrence of cancer several times higher than the usual range of people. "...
Under environmental factors, to ferret out the pain of those pathogenic "cancer"
"Environmental factors on health hazards as we known SARS virus and H7N9 virus infection, it presents is a long, lagging the carcinogenic process, it is possible in the next 30 years, 40 years, 50 years later, the only truly ' Enjoy 'to environmental pollution to the public about the health hazards caused by the medical profession so that it can not be defined under certain environmental conditions for the existence of cancer-causing factors, so many people do not pay attention carcinogenic environmental hazards, "said president Fu Jianhua.: "For example, there are more than 4000 kinds of tobacco harmful substances, including 69 kinds of cancer associated with these harmful carcinogens after a long period of influence and stimulate bronchial mucosa, finally leading to the bronchial epithelium cancerous."
A carcinogenic environment: Occupational Exposure
It is estimated that about 4% - 20% of cancers can be directly attributed to occupational exposure. Epidemiological studies have found that chimney sweep workers scrotal cancer-prone; production of benzidine dyes, or A, B naphthylamine workers bladder cancer-prone; engaged in the production of asbestos workers lung cancer-prone; engaged in X-ray, people isotope work leukemia-prone; tin miners with lung cancer-prone. The phenomenon occurs due to occupational carcinogens in the environment in concentrations much higher than ordinary environment, and occupational exposure to carcinogens crowd earlier, a large dose of cumulative exposure, resulting in cancer incidence and mortality than the general population. Therefore, to reduce the concentration of carcinogens in occupational environments, reducing occupational groups of cancer incidence and mortality have effect a permanent cure.
Carcinogenic environment II: indoor air pollution
Mankind has experienced a coal-burning type of air pollution and photochemical smog, has entered to indoor air pollution as a symbol of a new era of pollution. Research shows that about 68% of human diseases are associated with indoor air pollution. Interior decoration is one of the major sources of indoor pollution in urban and rural residents. Formaldehyde is a newly renovated main house indoor environments invisible killer. Long-term exposure to formaldehyde can cause a variety of cancers nose, mouth, throat, skin and digestive tract. There are reports that smoke produced by tobacco smoke is the most dangerous human carcinogen. The isolated compound from the tobacco smoke and 60 species are certain carcinogens or cancer activator or accelerator. These compounds include tar, carbon monoxide, hydrogen cyanide, phenols, ammonia, formaldehyde, benzene, nitrosamines and nicotine. Smoking is an important cause of lung cancer is well known, while passive smoking can induce lung cancer in non-smokers.
Environmental carcinogens three: chemical pollution
Large-scale application of chemical pollution caused by household detergents will increase the incidence of cancer. Data show that the higher chlorine content in detergents, easy to cause harm to humans, and acute leukemia, malignant lymphoma, neuroblastoma, and liver cancer. Meanwhile, the daily life of pesticide residues in vegetables and fruits are likely to cause cancer, such as organophosphate pesticides increases the risk of Hodgkin's lymphoma; organochlorine pesticides may increase the risk of leukemia
