From the article: "Until the late 1930s, stomach cancer was the No. 1 cause of cancer deaths in the United States. Now just 1.8 percent of American cancer deaths are the result of it. No one really knows why the disease has faded — perhaps it is because people stopped eating so much food that was preserved by smoking or salting. Or maybe it was because so many people took antibiotics that H. pylori, the bacteria that can cause stomach cancer, have been squelched."
