Early detection of precancerous adenomas by colonoscopy can prevent the development of cancer.
A study of over 224,000 patients and more than 314,000 colonoscopies found that adenoma detection rates closely tracked the future risk of colorectal cancer. The study was published in The New England Journal of Medicine.
Colonoscopies screen for colorectal cancer by detecting early, curable cancers. Precancerous adenomas — a type of colon polyp — can also be detected and removed, thereby preventing cancers from developing.
“We found that higher levels of detection were associated with a decreased subsequent risk of cancer,” said Douglas A. Corley, MD, PhD, a gastroenterologist and research scientist with the Kaiser Permanente Division of Research. “Taking out adenomas prevents cancers, and early detection likely prevents many cancers.”
The study is the largest ever conducted and the first in the United States to examine the relationship between detecting adenomas and the future risk of colorectal cancers.
