Quick to light up despite the potential risks? Take note: there may be a way to rapidly predict your chances of developing lung cancer – and provide yet more incentive to kick the habit. Researchers have discovered that smokers who excrete high levels of two tobacco metabolites (chemicals produced when the body breaks down tobacco) in their urine are up to 8.5 times more likely than those who excrete low levels to develop lung cancer.
"If we can identify a smoker with a high level of metabolites, and down the road they have a higher risk of lung cancer, public health workers can get them motivated to quit smoking,” lead researcher Jian-Min Yuan, a cancer epidemiologist at the University of Minnesota in Minneapolis, told Bloomberg News.

Foods containing a widely used additive may increase the growth of lung cancers or cause new tumors to develop, new research suggests.
Tumors were more plentiful in mice with lung cancer fed a diet containing 0.5 to 1 percent inorganic phosphates (equivalent to the 40 mg. that humans on average consume daily) for a month according to a study in next month's American Journal of Respiratory and Critical Care Medicine. The tumors' mass increased by 14 percent in the mice fed the most phosphates.
Inorganic phosphates are chemicals added to a variety of processed foods including cheese, meat, beverages and bakery products to increase water retention and improve their texture. The additives may disrupt the regulation of cell growth in the lungs, causing tumors to develop, says Myung-Haing Cho, a veterinarian at Seoul National University who co-authored the study.
