Colon cancer rates are dropping... as are deaths from the disease.
The good news is attributed to increased cancer screening.
The American Cancer Society reports a 30-percent drop in colon cancer incidence in the past decade for people over age 50.
And fewer people are dying of colon cancer.
From 2001 to 2010, mortality rates decreased by about 3-percent per year.
Colonoscopy screening tripled among older adults from 19-percent in 2000 to 55-percent in 2010.
Colonoscopy and other colon cancer screening tools are effective because doctors can find polyps and remove them before they become cancerous.
The American Cancer Society's chief medical officer says there's no doubt about the benefits of colorectal screening.
The American Cancer Society and similar organizations recommend most people start colon cancer screening at age 50.
That can be a colonoscopy every 10 years, a sigmoidoscopy every 3 to 5 years, or stool blood testing three times a year.
Those with a family history or other risk factors may need to start screening earlier.
