Study Ties Pollution, Risk Of Lung Cancer

Bad Credit Credit Creditres Researchers for the first time have linked long-term exposure to fine particles of air pollution from coal-fired power plants, factories and diesel trucks to an increased risk of dying from lung cancer.

Flavonoids have also been associated with a reduced risk of lung cancer and one case control study reported a 50% reduction in lung cancer risk when consuming 1 cup of black tea a day. However, another study that investigated the relationship between catechin intake (a type of flavonoid that is abundant in tea) and lung cancer, found no such association34. Other studies investigating the relationship between tea drinking and lung cancer also reported no association.

Bad Consolidation Credit Debt A study published in today's issue of the Journal of the American Medical Association concludes that people living in the most heavily polluted metropolitan areas have a 12 percent increased risk of dying of lung cancer than people in the least polluted areas. The study's authors said that exposure to the tiny particles of industrial emissions and sulfate pollutants is comparable to inhaling second-hand smoke from a cigarette.

Cancer of the lung is the leading cause of death from cancer in both men and women in the United States. Cigarette smoking is by far the most important risk factor for the development of lung cancer. Air pollution is another risk factor. A previous diagnosis of tuberculosis increases the risk of lung cancer by 5 to 10%. Top.

Bad Company Credit Repair The latest findings come as the Bush administration is considering proposals for scaling back tough government legal action against dozens of aging coal-fired power plants and refineries that violated the law by expanding without installing state of the art anti-pollution equipment. Power plants built before 1980 generate about half the nation's electricity but nearly all of the utility industry's unhealthy sulfur dioxide, nitrogen oxide and soot, experts said. Environmental groups seized on the new findings as support for their position that tough enforcement was still needed.

Incidence of lung cancer correlates with dietary fat intake from country to country.11 Some, 12 but not all, 13 preliminary studies report consumption of saturated fat in both meat and dairy fat correlates with the risk of lung cancer, even among nonsmokers.14 Lung cancer risk appears directly related to consumption of foods containing saturated fat–– cooked meat.15 In one trial that was unable to find an association between lung cancer risk and total saturated fat intake, people consuming skim milk nonetheless had a 50% fat milk.16.

Bad Card Credit Credit Air pollution levels have declined significantly during the past 20 years because of stepped-up enforcement of clean air laws, yet levels of fine particle emissions in New York, Los Angeles, Chicago and Washington are at or exceed limits set by the Environmental Protection Agency.

Untreated, women with lung cancer live longer than men Women with lung cancer are living longer than men, even when the disease is untreated. A new study presented at CHEST 2005, the 71st annual international scientific assembly of the American College of Chest Physicians (ACCP), found that in patients receiving treatment for lung cancer, women had significantly better survival rates than men. However, in untreated patients, women also had a 21 percent decreased risk of death as compared with men, leading researchers to believe lung cancer in women has a different biologic behavior and natural history than in men.

Bad Car Credit Loan Fine particles are compounds and pollutants produced through combustion in power plants, refineries, diesel trucks and buses. They are so tiny smaller than 2.5 microns or a fraction of the thickness of a human hair that they evade the human lung's natural defenses and are inhaled deeply.

Avoidance of meat and saturated fat done red meat was associated with an elevated risk of lung cancer in one report.8 Consumption of red meat in general, as well as fried meat, correlated with a high risk of lung cancer in another study.9 People who cook with fat taken from meat (such as bacon fat and lard) have also been reported to be at high risk of lung cancer according to preliminary research.10.

Bad Credit Loan Mortgage Previous research by Harvard University and the American Cancer Society strongly linked these fine particles to high mortality rates from cardiopulmonary diseases such as heart attacks, strokes and asthma. Until now, however, scientists lacked sufficient statistical evidence to directly link those emissions to elevated lung cancer death rates.

Auto Bad Credit Loan By gathering air pollution data and 16 years of personal health records of 500,000 of the people who had participated in the earlier American Cancer Society study, scientists amassed the "statistical fire power" to finally make that connection, said Bringham Young University epidemiologist Arden Pope, a chief author of the study.

Bad Credit Mortgage Refinance Allen Dearry, a scientist at the National Institute of Environmental Health Sciences, which partly funded the study, called it "the best epidemiologic evidence that we have so far that that type of exposure is associated with lung cancer death."

Bad Credit Refinance Environmentalists, public health advocates and citizens groups contend that power plant emissions are among the worst contributors to the lung and heart disease problems highlighted by the new study. Brian P. Urbaszewski, director of environmental health programs for the American Lung Association of Metropolitan Chicago, said the study "is another nail in the coffin for these old coal-fired power plants."

Bad Credit Mortgage Second However, industry officials contend that the link between power plant emissions and the elevated mortality rates is not all that clear, and that there are limits to how much utilities can spend on anti-pollution measures and remain competitive.

Bad Credit Loan Student "We as an industry have dramatically reduced emissions, and more reductions will be made because they are required under existing regulations," said Jayne Brady, a spokesperson for the Edison Electric Institute, a utility group. Brady added that the new cancer study is just "one of many studies."

Bad Card Credit An EPA spokesman said the agency was "interested" in the new findings but that officials have not fully assessed it yet.

Bad Credit Financing The scientific and legal controversy over the health effects of fine particle emissions has raged for years, culminating in the EPA's decision in 1997 to issue tough new standards limiting the annual average level of fine particles in the air to 15 micrograms per cubic meter. The Supreme Court upheld the standards in February 2001, but then remanded them to a lower court for further consideration.

Bad Credit Home Loan Mortgage The landmark studies published by Harvard researchers in 1993 and the American Cancer Society in 1995 documented a high incidence of premature deaths among people chronically exposed to fine particle emissions.

Bad Credit Loan People Nationwide, as many as 30,100 deaths a year are related to power plant emissions, according to a study by Abt Associates, a private research organization that does work for the EPA. By comparison, 16,000 Americans are killed each year in drunken driving accidents, and more than 17,000 are victims of homicides.

Bad Card Credit Credit People Industry officials and some scientists have disputed these findings and argued that the past research failed to account for many variables, such as regional disparities and an individual's occupation and diet.

Bad Credit Guaranteed Loan The newly released study conducted by Pope, George Thurston, professor of environmental medicine at New York University's School of Medicine, and Daniel Krewski of the University of Ottawa sought to address the criticism in doing follow-up studies of a half-million people living in 100 cities throughout the country.

Bad Credit Refinancing The researchers first took into account other risk factors for heart and lung disease such as cigarettes, diet, weight and occupation.

Bad Credit Equity Home Loan Lung cancer death rates were compared with average pollution levels, as measured in micrograms per cubic meter of air. The researchers found that the number of lung cancer deaths increased 8 percent for every increase of 10 micrograms. Other heart- and lung-related causes of death increased 6 percent for every 10 microgram increase.

Bad Credit Loan Payday At the study's inception in 1982, the most polluted cities had fine particulate pollution levels about 20 micrograms per cubic meter higher than the least polluted cities. As a result, residents in the most polluted cities had an approximately 16 percent excess risk of dying from lung cancer due to fine particulate air pollution, the study shows. By the end of the study in 1998, the air had become somewhat cleaner, reducing that risk, but it remained 12 percent higher in the worst polluted areas, the authors found.
