FNED 195-061 Assignment Topic: Occupation and Cancer Occupation and Cancer Occupational exposure to carcinogens is thought to account for about 4% of all cancers in the United State. Although occupational exposure to carcinogens has been reduced in recent decades, current statistics may reflect occupational exposures that occurred long in the past and are just now being identified. It is known that certain chemicals (e.g. benzene, nickel compounds, vinyl chloride), dusts (e.g. leather or wood dusts, silica, asbestos), radiation (e.g. sunlight, radon gas, industrial, medical, or other exposure to ionizing radiation), and industrial processes (e.g. aluminum production, iron and steel founding, underground mining with exposure to uranium or radon) are occupational exposures that can cause cancer. In the United States, nearly all of these exposures are regulated, but potential exposure can occur through accidents, breaches in regulation, or unrecognized hazards. So, which kind of chemical compounds can cause cancer and further what kinds of cancers? Why do scientists think they can cause cancer? We should know what they are, and what will happen if we are exposured to them. What kind of job will have to be exposured to that kind of carcinogens? Employees or employers use all kinds of chemical compounds in some workplace and some compounds are a kind of carcinogens, both of which are bad for workers ‘health. So which kind of compounds can exposure and which kind of compounds can’t exposure. I get some information about Occupation and Cancer from internet. These information will answer the entire question mentioned above. Which kind of chemical compounds can cause cancer and what kind of cancers? We can get it from the table below. This table presents information on occupation and cancer risk. The table shows a summary of what we know about occupational exposure to carcinogens and the cancers they are related to. Occupational exposures classified as human carcinogens by
