The original five things to do this can cause cancer

Cancer may be a killer: lifestyle inappropriate
Ministry of Health issued the "China Health Statistics" shows that residents in some cities the top 5 causes of death were: cancer, cerebrovascular disease, heart disease, respiratory disease, injury and poisoning. This indicates that the disease caused by improper lifestyle have become urban residents in China threatening the life of the most important reason. The number of deaths due to improper way of life accounted for 37% of the total deaths. Medical reason for making "lifestyle cancers" concept, is to remind people to pay attention to their lifestyle, get rid of bad habits.
Experts point out that smoking, alcohol, often stays up late for supper, or even in the streets breathing automobile exhaust inhalation of cooking at home, the fumes released when fog, etc., there is a possibility of cancer. All in all, the basic needs of human unhealthy may have caused cancer, this cancer is the "way of life cancer."
Lifestyle changes can indeed alter the probability of cancer, which is to prevent "lifestyle cancers" the greatest force. Female malignancies, for example, liberation of women in Shanghai in order first cervical cancer has now dropped to eighth in the School of Medicine conducting clinical teaching has been difficult to find living examples of advanced cervical cancer, information only to the students pictures of breast cancer over the past few see now routed to the first impact of lifestyle change which is sort of female cancers most vivid example. Because cervical cancer and many children, early marriage, etc., whereas the incidence of breast cancer is and nutrition, breast-feeding too little about.

 
Killer cancer may be two: the external environment pollution
Experts point out that the vast majority of cancers are not caused only by internal or external causes, but by a variety of factors, internal and external due to interaction, interaction results. The external factors are mainly environmental factors. Cancer Epidemiology studies show that 90% of the cancer and the environment. Environmental factors include our daily lives come into contact with almost all substances, such as food, water, air, drugs, chemicals, radiation and micro-organisms (eg bacteria, viruses) and so on. Environment can be divided into biological, chemical and social environment of three parts, mainly chemicals. Therefore, some experts pointed out that the current increase in the incidence of cancer is a major cause of the result of a large number of chemical substances.
Since the acceleration of urbanization, population density, pollution is serious, living conditions and lifestyle changes makes it the spirit of high tension, the pace of life accelerated, adding to the mental burden. At the same time there are many cancer-causing human factor in the environment, resulting in some cancer, and most people are for life not cancerous. This shows that the body's own internal factors on the incidence of cancer or not play an important role. In layman's terms, mutant cells as "seed", the body's internal environment as "soil." With the seed of cancer, but also the soil for the growth of cancer cells, coupled with the external environment as a fertilizer, such neoplasms were able to grow.

 
Killer cancer may be three: the proliferation of chemical substances
Cancer expert Professor Hu Chaosu Hospital pointed out that studies have found that some foods contain a chemical can cause cancer. Such as consumption of pickled and moldy food, etc., which, dimethylnitrosamine, diethylnitrosamine and methyl benzyl nitrosamine can be in the curing of meat and fish, rough fish sauce found. In addition, radish Chen, Chen cornmeal, sauerkraut and some moldy foods are also more or less exist. Moldy food in addition to nitrosamines but also have a fungal toxin, the toxin itself can cause cancer, but also a synergistic carcinogenic nitrosamines. Experts also found high incidence of gastric cancer fungal contamination of food and food seriously, even in patients with gastric cancer, also detected fungi and their toxins.
According to international epidemiological studies, the incidence of gastric cancer may also be delicious BBQ meal. BBQ food in the process because it will produce a large number of polycyclic aromatic hydrocarbons, which contain strong carcinogen benzopyrene, etc., it permeable to the whole food. BBQ, the protein at high temperatures, especially in the decomposition of carcinogenic when burned components.

 
Cancer killer of four may be: diet nutrition
Cause of death of every 5 patients, there is one case died of cancer. 4 cases the cause of death for each city in one case died of cancer, many patients with this intermediate nutrition related.
Epidemiological surveys show that high-fat will affect the intestinal flora and some of the bile acid and cholesterol levels, and these can become a catalyst for colon cancer. Dietary fat intake and a positive correlation between the prevalence of colorectal cancer, people with higher fat intake was significantly higher colorectal cancer incidence. Vice president of Shanghai Institute of Nutrition Professor Jiang Jiakun point out that eating a single, flour, rice, very little food grains, making the body heat increases, the incidence of cancer is one of the incentives. As early as 40 years in the last century, some people have done in animals some interesting tests. They found that feed intake restriction in mice, a reduction of sugar intake (to reduce heat supply), can significantly reduce the incidence of cancer. In some cancer patients had similar findings. Overweight people are also prone to certain cancers, such as gallbladder cancer, uterine cancer more often than other people greatly increased.
Excessive alcohol consumption is an important factor in inducing cancer. Excessive alcohol consumption and oral cancer, pharyngeal cancer, laryngeal cancer, esophageal cancer, liver cancer, rectal cancer, breast cancer, are closely related. For the mouth, throat, the cancer, the incidence of excessive drinkers than non-excessive drinkers more than 2 times higher. Esophageal cancer and alcohol are more closely related.

 
Cancer killer of five possible: Psychological factors may also become an incentive
Scientists have discovered that a large number of environmental factors and the pathogenesis of cancer. At the same time, scientists study also showed that psychological factors can also be the incentive of cancer.

 
There experiments confirmed: in a good mood, the brain's emotional center will secrete a kind of healthy "brain endorphin" substance that can pain, but also anti-aging, and can activate the immune system, inhibit the growth of cancer cells and harmful microorganisms. In contrast, in a bad mood when the adrenaline will increase the secretion of corticosterone, the hormone into the blood, can damage immune function, trigger normal cell cancerous. American scholars have conducted surveys of 8,000 cancer patients, the majority of clinical manifestations of malignant tumors have occurred in disappointment, loneliness, and other heavy combat during the frequent occurrence of mental stress. Our survey data also show that many of the first half of cancer patients have a greater incidence of mental stimulation, the rate of more than 50%.
