This provocative study demonstrates that biological age, which can be evaluated by a blood test, is associated with a higher incidence of precancerous colon polyps.” — Anton Bilchik, MD, PhD ...
The figure in this section includes a photo of a freshly resected and lengthwise-opened segment of the colon showing a colon cancer and four polyps.
