Two components of red meat – dietary protein and dietary iron – may combine to form powerful carcinogens, N-nitroso compounds, which increase risk for bladder cancer. Moreover, individuals with reduced ability to reverse the effects of N-nitroso compounds because of a genetic variation in their RAD52 gene could be at particularly high risk. Chelsea Catsburg, a doctoral student at the Keck School of Medicine of the University of Southern California, Los Angeles, presented these...

Lee Rannals for redOrbit.com - Your Universe Online Scientists reported in Philadelphia at the 244th National Meeting & Exposition of the American Chemical Society today that they have identified the first oral carcinogen in smokeless tobacco. Researchers said this is the first identification of a strong oral cavity carcinogen found in smokeless tobacco products. "Our results are very important in regard to the growing use of smokeless tobacco in the world, especially among...

The addition of ascorbate (vitamin C) or its close relative, erythorbate, and the reduced amount of nitrite added in hot dogs, mandated in 1978, have been accompanied by a steep drop in the death rate from colon cancer, according to data presented at the 10th AACR International Conference on Frontiers in Cancer Prevention Research, held Oct. 22-25, 2011. However, the incidence rate for colon cancer has apparently not changed much since 1978, according to 2011 data from the SEER Cancer...

CO2 capture by means of amines is considered to be the most appropriate method to quickly begin with CO2 removal. During this capture process, some of the amines escaping the recycling process will be emitted into the air and will also form other compounds such as nitrosamines and nitramines. The Norwegian Institute of Public Health (NIPH) was commissioned by the Climate and Pollution Agency (Klif) to assess whether these new emissions are harmful to health - particularly in terms of the...

Since being linked to an increased risk of cardiovascular disease and cancer of the pancreas, red meat has been found by a team of US researchers to be a possible cause of bladder cancer. There is some good news however; scientists found no links between beef, bacon, hamburger, sausage or steak and bladder cancer. The bad news: the team did observe a "positive nonlinear association for red meat cold cuts" and bladder cancer. The culprits are nitrates and nitrites which are added to meat...

A new study suggests that consuming specific compounds in meat related to processing methods may be associated with an increased risk of developing bladder cancer. Published early online in CANCER, a peer-reviewed journal of the American Cancer Society, the findings may be relevant for understanding the role of dietary exposures in cancer risk. Eating red and processed meats has been linked to an increased risk of developing several different types of cancer. Animal studies have identified a...

Scientists are reporting evidence that certain ingredients in shampoo, detergents and other household cleaning agents may be a source of precursor materials for formation of a suspected cancer-causing contaminant in water supplies that receive water from sewage treatment plants. The study sheds new light on possible environmental sources of this poorly understood water contaminant, called NDMA, which is of ongoing concern to health officials. Their study is in ACS' Environmental Science &...

PETERSBURG, Va., Sept. 22 /PRNewswire-FirstCall/ -- Star Scientific, Inc. (Nasdaq: STSI) makers of low-nitrosamine smokeless tobacco products, announced today that the company will utilize a novel, patented method for cultivation, curing and preparation of tobacco to formulate dissolvable smokeless tobacco products. This new curing process was the subject of a patent application filed in December, 2008. Its use has resulted in tobacco leaf with significantly lower levels of tobacco-specific...

Attention all smokeless tobacco users! It's time to banish the comforting notion that snuff and chewing tobacco are safe because they don't burn and produce inhalable smoke like cigarettes. A study that looked beyond the well-researched tobacco hazards, nitrosamines and nicotine, has discovered a single pinch "“"“ the amount in a portion "“"“ of smokeless tobacco exposes the user to the same amount of another group of dangerous chemicals as the smoke of five...

A new study by researchers at Rhode Island Hospital found a substantial link between increased death rate from certain age-related diseases and increased exposure to nitrates, nitrites and nitrosamines in processed foods and in the environment. The researchers note that the role of nitrosamines has been well-studied, and their role as a carcinogen has been fully documented. The investigators propose that the cellular alterations that occur as a result of nitrosamine exposure are fundamentally...
