Colon and rectal cancers rates rising sharply among Gen X and millennials

Rates of colon and rectal cancer, which overall have been declining for decades in the United States, are instead rising sharply among Americans under 55, according to a new study led by American Cancer Society. Lead researcher Rebecca Siegel, suggested that prime suspects for the cause include obesity, inactivity and poor diets. Because routine screening is generally not recommended for most people under 50, these cancers are often found in more advanced stages, too.
