The decline in deaths from all cancers combined continued in the USA from 2004-2008, but a major government report highlights a worrisome rise in cases linked to obesity and inactivity. Although the overall rate of new cancer cases is declining, the report confirms research showing that excess weight and a sedentary lifestyle are risk factors for one-quarter to one-third of common cancers in the USA.
