Olivia RovegnoThesis Statement: Second hand smoke is a cause of cancer. Data: Newspapers 1. 'When these new data for cervical cancer are considered in light of similar results from previously published studies, our findings suggest that passive smoking may be firmly linked with cervical cancer,' wrote lead author Anthony J. Albert. 'Our study of two large cohorts found that women who lived with smokers had a percent or greater risk of developing cervical.' excerpt from Second hand smoke, cervical cancer linked. UPI News Track, Jan 5, 20052.

The CDC said secondhand smoke exposure is on the decline across the United States but that it remains a public health hazard. It contributes to approximately 3, 000 lung cancer deaths and more than 35, 000 coronary heart disease deaths annually among people who have never smoked, the agency said. excerpt from Laws reduce second hand smoke UPI News Track, November 10, 2004 3. Jamrozik's calculations said about 700 people die from lung cancer, heart disease or stroke because of passive smoking at work. Another 3, 600 people die as a result of second-hand smoke at home. 'In the absence of a direct observational study, I feel this research is the best evidence we have in this country to show the effects of passive smoking in the workplace,' Jamrozik's told the BBC.

excerpt from Study: Second Hand Smoke Kills Thousands UPI News track, May 16, 2004 4. A comprehensive review of medical studies by researchers at the International Agency for Research on Cancer showed second-hand smoke causes cancer, and that chemicals and gases in tobacco contributed to cancer of the stomach, liver, kidney, uterine cervix, and also to myeloid leukaemia. excerpt from Step Up Anti-Smoking Campaign, State Urged Africa News Service, September 13, 2002 Journals/ Magazines 1. In 1986 the National Research Council of the National Academy of Sciences produced a groundbreaking report on the health effects of environmental tobacco smoke. After reviewing the evidence, the Council concluded that secondhand smoke was responsible for 3, 000 deaths from lung cancer each year in the United States.

Since then, the connection between secondhand smoke and lung cancer has grown steadily. One study found that 'passive smoking' raises a nonsmoker's chance of getting lung cancer by 26 percent. In 1992, the United States Environmental Protection Agency classified secondhand smoke as a Group A carcinogen, the category reserved for the most dangerous cancer-causing substances. Secondhand smoke contains more than 4, 000 chemicals, at least 40 of which are suspected to cause cancer. excerpt from Why Second Hand Smoke is a First Hand Hazard Current Health 2, a Weekly Reader publication.

Nonsmoking adults chronically exposed to pollutants emitted by the cigarettes of a spouse or coworkers face a roughly 20 percent increased risk of lung cancer, according to a new study conducted jointly at centers throughout Europe. That i n crease disappears, however, if exposures occurred only during childhood or ceased at least 15 years ago, the authors report in the Oct. 7 JOURNAL OF THE NATIONAL CANCER INSTITUTE. Paolo Boffetta of the International Agency for Research on Cancer in Lyon, France, and his coworkers studied the smoke- exposure history of 650 people with lung cancer and 1, 542 others who were free of all diseases linked to cigarettes. None of the participants had ever smoked. This 'eagerly awaited's tudy 'is among the largest and most exhaustive examinations of passive smoking's effects on lung cancer,' comment William J, Blot and Joseph K.

McLaughlin of the International Epidemiology Institute in Rockville, Md. , in an editorial accompanying the new report. The new European data reinforce a host of earlier, weaker studies. When all are considered together, Blot and McLaughlin argue, 'the inescapable scientific conclusion is that environmental tobacco smoke is a low-level lung carcinogen' and that investments in antismoking campaigns stand to benefit both smokers and others.
