Ten newly identified cancer-causing substances

The experts in determining the hazard of tamoxifen quite nerve-racking. Because this is to prevent the high incidence of female breast cancer, an effective drug, but also to prevent the recurrence of the disease. Previously found that the drug than many chemotherapy drugs much more secure, however, the drug also increases the risk of uterine cancer risk. U.S. Food and Drug Inspection Bureau has never been clear the drug more advantages than disadvantages, but the U.S. Department of Health and Human Services, scientists are worried that the substance will make some use of tamoxifen for women uneasy.

Solar radiation and solar lights
Excessive UV-induced skin cancer is the devil.

2 oxy-biphenyl dyes
This crystal and paper products for the textile dyeing dye is harmless, but the inhaled or enter the mouth, there will be harm. Once the substance is the human body, it will break down into free two oxy-biphenyl, leading to bladder cancer.

The voices of people smoking has always been very strong. Now, is well known, in smokers, passive smoking atmosphere in the environment, that is, non-smokers can lead to lung cancer.

Cigarettes and cigars
There is no doubt that cigarettes and cigars are well-known carcinogen. Particularly in developing countries, tobacco is often a malignant lung, throat and esophageal disease, the main factors.

Alcohol will not only result in cirrhosis of the liver, but also lead to the mouth, throat and esophageal cancer. The list of the report points out that alcohol is also related with liver cancer and breast cancer.

Phenol is an important industrial production of organic solvents in many industrial products are used in it. Example Decoration in the paint, and even criminals using scrap CD production of "poison" bottle and other plastic products all contain it. It represents to human liver, kidney and other organs damage is considerable.

Ethylene oxide
Ethylene oxide is generally used to disinfect hospital equipment, the substance will increase the non-Hodgkin's lymphoma and leukemia. Patients in hospitals will not necessarily be in under the threat of it, because volatile chemicals will not leave marks, but is at risk is the use of the substance of nurses and doctors.

  1. The people most at risk of exposure to ethylene oxide (EtO) in hospitals are the workers in central services or sterile processing departments, who use the sterilizers. The odor threshold for EtO is around 400 to 700 ppm, and the OSHA permissible exposure limit for EtO is only 1 ppm, calculated as a time weighted average, so any EtO leaks are imperceptible to smell until the concentration is many times the dangerous level. Hospitals can help ensure the safety of their employees by installing continuous monitors that sound an alarm if there is a leak and also track cumulative exposure to make sure the PEL is not exceeded as well. Continuous monitors are available from several supplies, see for example
