Job-related cancer

Increasingly higher incidence of cancer so that modern people can not avoid the heavy topic, but for some occupations, the cancer risk is clear.  Ministry of Health issued the "Chinese Journal of Cancer Prevention and Control Plan" (2004 -2010 years), occupational hazards have been ranked in smoking, hepatitis B virus infection and dietary unreasonable, serves as one of the most important factor in cancer.

Occupational cancer is not a small problem

Cancer Hospital, Peking University, Institute of Epidemiology, Nutrition and Cancer Laboratory Professor Zhang Lian told the "Life Times" reporter, occupational cancer, refers to industry-related factors from the tumor. And the risk of cancer than the general population, there is no difference between a so-called standards, but "when a certain industry, the incidence of certain cancers was significantly higher than other groups when" we can say that cancer is the industry, "Occupational Cancer."

"It is estimated that malignant tumors in China, occupational cancers account for about 5%." Director Zhang said, according to the proportion in China is currently around 200 million annual new cancers patients, about 10 million are "occupational cancer" . Two years ago, a study in France has attracted worldwide attention: 10% of cancer cases in France and career related. Among them, over the age of 55 lung cancer patients, 12% of people have been exposed to asbestos. There are data, and the proportion of work-related respiratory tract cancer and 13% -29%; 5% of the European leukemia cases and the work environment, the United States was 10%.

Director Zhang said that the main environmental factors of cancer is a disease. World Health Organization will be divided into four carcinogenic substances, the first level is clearly related to human cancers, such as arsenic, asbestos, benzene and coal tar, etc.; The second level may be associated with human cancers, such as aflatoxin , cadmium, carbon tetrachloride and strong herbicide. The information presented in the Director Zhang, the reporter saw 18 species level of 15 carcinogenic substances mainly from the professional environment, are also 18 species of secondary material up to 13!

What are the career most of the attention of cancer

Professional relationship between environment and cancer is so close, then, what occupations the most serious threats to it? Director Zhang introduction, asbestos production, leather, paper, chemical fiber, chemical and metal smelting industry workers face the greatest risk of cancer. At the same time, he told several reporters about the closer relationship with the working environment "Occupational Cancer":

Lung Cancer: Asbestos, arsenic processing, cadmium, coal tar and other related industries; bladder cancer : leather, aluminum, magenta manufacturing and other industries; NPC : exposure to formaldehyde, isopropyl alcohol, asbestos powder, mustard gas and other industries as well as leather industry; lymphoma and leukemia: benzene exposure (such as printing), vinyl chloride, X-ray and other industries; liver cancer : exposure to arsenic, vinyl chloride workers.

Director Zhang said that these carcinogens mainly through inhalation, oral, skin contact with other ways into the human body. Often related to a long latency of cancer, such as lung cancer, bladder cancer, and so may take up to a dozen two decades, it should be noted that daily protection.

We must actively fight against occupational cancer

Now, prevention of occupational diseases has been great concern in all levels of government, introduced the "Occupational Disease Prevention Law." Specific to occupational cancer, Director Zhang believes that we should do the following tasks:

First, to reduce exposure to practitioners and carcinogens. Such as improving the level of production automation, and choose safer alternatives. Second, improve the working environment, strict implementation of occupational health standards, especially small and medium enterprises, but be careful not to give up because of profit-oriented work environment improved. Third, to strengthen the personal protection of workers, improve health awareness. Such as washing hands, bathing, changing clothes frequently, work wear masks and other protective equipment. At the same time, but also pay attention to exercise, proper diet, to improve their resistance. Finally, regular physical examination. The key to early detection examination, annual physical examination is very important. "If the usual old cough, nasal bleeding , intestinal upset stomach to doctor immediately. "

"All cancers are preventable, the key is to reduce the chance of its onset." For occupational cancer, improve the working environment, strengthen the protection of the most effective way. In addition, more human and material resources, some new technologies to study cancer risk, but also very necessary.
