What career with the occurrence of cancer-related
[an error occurred while processing this directive]

In the course of labor and labor households in the cancer-causing environmental factors may lead to the occurrence of workers of various types of cancer, known as the occupational cancer. Industrialized countries, occupational cancer, the incidence of cancer of the total of 2% to 8%; developing countries the incidence of occupational cancer cases are aware of very little. Occupational cancer is a major factor in cancer-causing chemical carcinogens and ionizing radiation. From the workers came into contact with cancer-causing factors to the occurrence of cancer is a long process, and in some cases contact is not continuous, change jobs or retire cancer patients often ignored in the past in professional contact with cancer-causing factors.

     Occupational cancer most often occurs in the skin, lung and bladder, it is because they are easy to access parts of carcinogens have been absorbed (such as lung and skin) or discharge (such as the bladder).

                            
     Occupational skin cancer often of arsenic exposure in the mine, arsenic pesticides and chemical workers; contact with coal tar and soot of industrial furnaces, industrial resins and asphalt work; contact with X-ray radiation and the medical staff and scientists.

                            
     Occupational bladder cancer often filthy place in the production of dyes and pigments workers; contact with the rubber tire and rubber producers workers; contact with coal tar polycyclic aromatic hydrocarbons and gas workers, aluminum workers.

                            
     Occupational lung and bronchial cancer often occurs in contact with arsenic and coal tar types of work; also occurred in contact with chemical solvents and organic chemicals producers and Painter; chromium and nickel compounds producers and welder; asbestos mine Mining and processing of the miners and workers exposed to asbestos pleural mesothelioma occurred in people who are not much higher than the contacts.

     Benzene exposure or radiation-prone members of leukemia, vinyl chloride producers prone to liver cancer and liver angiosarcoma.

                            
     Occupational cancer-causing factors do exist in certain occupations, but the risk of cancer to a large extent depend on the productive sectors of health care prevention and control measures are effective.

                            
     First of all, to strengthen health care is necessary to strengthen health education to enable employees to understand the characteristics of carcinogens, into the way the human body and protective measures. To the rational use of protective equipment, the establishment of safe production system on a regular basis to monitor the concentration of carcinogens in the environment, periodic inspection of health workers.

                            
     In the production process should be to control and eliminate the production of carcinogens. If using non-toxic or low toxic material to replace toxic carcinogens; can not be avoided, such as the use or production of cancer-causing effects of the material should be restricted in the raw materials of toxic substances, to minimize the production of cancer-causing substances to the environment, emissions, ventilation, Reduce dust emissions; the reform process, as far as possible the use of automation and mechanization of production and sealed to reduce the cancer-causing substances in direct contact with human body
