General practitioner measuring waist of obese patient
From "Obesity: 'Like the New Smoking,'" in the LA Times Health section today:
"[The American Institute for Cancer Research] estimated about 100,000 Americans get a cancer they wouldn't have gotten if they had kept their weight in check. And researchers have estimated that about 14 percent of cancer deaths in men and 20 percent in women could be avoided by this same restraint."
Not only is there strong evidence that if you're overweight, you're more likely to die of cancer. It's also been shown that the more overweight you are, the more deadly the trend gets, according to a landmark study published in the New England Journal of Medicine in 2003.
