The relationship between cancer and occupation is a professional production environment in the long-term exposure to specific carcinogens caused cancer. Career-related cancers account for about 4% of all cancer. In China, the largest proportion of lung cancer, accounting for about 90%
And occupational causes of cancer related to relatively clear, divided into the following two situations:
First of all, are known to cause cancer and occupational factors are mainly related to chemical factors. Recognized occupational carcinogens are: groan, asbestos, benzene, biphenyl plastic, nitroso clothing, chlorine tea stare much, dichloromethyl and chloromethyl a cool tunnel, coal compounds, coal tar pitch, coal tar Class, raw or lightly processed mineral oil, 2 a tea gum, shale oil, soot, asbestos-like fibers in talc, vinyl chloride.
Secondly, the frequent contact with staff of radioisotopes, such as uranium miners, etc., may also be due to the radiation dose received over cancer. Specific cancer-causing factors in the production process is not clear, but the workers engaged in the production; cancer incidence was significantly higher than other types of work. Such production processes currently known are: aluminum production, the production of shoes and boots, furniture production, coke production, hematite mining, steel casting, rubber production, isopropyl alcohol manufacturing process (acid method), magenta production.
What is the relationship with the occupational cancer, occupational-related cancers often occur in the skin, urinary tract and respiratory tract, because these areas often associated with carcinogen exposure (eg skin), or the absorption of carcinogens and their metabolites (such as skin, respiratory tract ) and excretion (such as urinary tract) when the contact.
