WASHINGTON: Death rates from cancer in the United States dropped again between 2014 and 2015, continuing a downward trend that began in 1991 and has meant 2.4 million fewer deaths, a study said Thursday. Advances in early detection and treatment, along with a drop in smoking, are believed to be responsible for much of the 26 percent drop since 1991, said the findings in the American Cancer Society´s comprehensive annual report. ?This new report reiterates where cancer control efforts have worked, particularly the impact of tobacco control,? said Otis W. Brawley, chief medical officer of the American Cancer Society. ?A decline in consumption of cigarettes is credited with being the most important factor in the drop in cancer death rates.? However, he noted that ?tobacco remains by far the leading cause of cancer deaths today, responsible for nearly three in 10 cancer deaths.?
