Screening Age
It’s Colorectal Cancer Awareness Month, a good time to remind you that experts now recommend routine screening for colorectal cancer beginning at age 45.
The screening age was lowered in 2021, as the number of young adults being diagnosed with colorectal cancer continued to rise, with many cases diagnosed at more advanced stages than in older adults eligible for screening.
Benefits of Earlier Screening
Earlier screening can help identify and remove growths in the colon or rectum called polyps before they develop into cancer — or catch cancer when it’s easier to treat.
Even if you’re younger than 45, you should see your doctor and ask about screening if you have a family history of colorectal cancer or are experiencing symptoms.
