The American Cancer Society updates colorectal cancer guidelines
If you're in your mid-40's and haven't had your colon checked, it might be time.
The American Cancer Society now says colorectal cancer screening should start at age 45 instead of 50.
The new recommended age is for people at average risk.
Those at high risk, including African-Americans and Alaska natives, should get screened even earlier.
The updated guidelines come in response to rising colorectal cancer rates and deaths in younger adults.
