The authors of new guidelines for colorectal cancer screening tweaked
existing recommendations while stressing the importance of initial screenings
for people aged 50 years or older.
The initial screen is especially important because it detects the largest,
most dangerous polyps, which can be removed through a polypectomy, according
to the American Gastroenterological Association. It also helps get patients
in the habit of screening, thus improving the chances of early detection of
colorectal cancer—a key factor in surviving this malignancy.
