The AP (2/3) reported, "About 40 percent of cancers could be prevented if people stopped smoking and overeating, limited their alcohol, exercised regularly, and got vaccines targeting cancer-causing infections," according to a report by officials at the International Union Against Cancer. In the paper, "experts said about 21 percent of all cancers are due to infections like the human papillomavirus, or HPV, which causes cervical cancer, and hepatitis infections that cause stomach and liver cancer." The report also noted that "nearly 80 percent of the world's cervical cancer deaths are in poor countries."
