40% of cancers are linked to being overweight

The rate of new cancer cases has decreased in the United States since the 1990s. But increases in overweight- and obesity-related cancers—which now account for 40% of all U.S. cancers—are likely slowing that progress, according to a new report from the Centers for Disease Control and Prevention (CDC).

In 2014, about 630,000 Americans were diagnosed with a cancer associated with excess body weight.
