Mortality rates for most cancers are declining globally, reports a study by the American Cancer Society and Brookdale University Hospital Medical Center. Researchers looked at eight major cancers—female breast, lung, colon and rectum, prostate, stomach, liver, cervix and esophagus—in 47 countries. Mortality rates decreased in most cases, except for lung cancer in women (mostly in Europe) and liver cancer in men. Liver cancer deaths were linked to hepatitis C, obesity and other factors. To reduce cancer risk, researchers suggest vaccinations, tobacco control, regular screenings and healthful lifestyles.
