People whose colonoscopies find adenomas – polyps that can become cancer -- are routinely asked to come back for another colonoscopy in three years, but a surprisingly high percentage fail to get the follow-up, a new study reports.

Women aged 20 to 49 who were overweight or obese had up to twice the risk for colon cancer before age 50, compared with normal-weight women, in a new study.

People in a recent study who drank one or more 12-ounce servings of artificially sweetened soft drinks a day had a 46 percent lower risk of cancer recurrence or death over the study period than those who didn't drink such beverages.

The chances of developing colon cancer decline about 19 percent in women and 7 percent in men for every incremental increase in blood vitamin D levels, the researchers found.

Researchers report that the rate of infections following these procedures at outpatient ambulatory surgery centers could be 100 times higher than previously believed, a new study finds.

Just last year, an ACS study found that since the mid-1990s, colon cancer rates among Americans aged 20 to 54 have been steadily inching up -- by between 0.5 percent and 2 percent each year.

Spotting polyps during a colonoscopy can be tricky, particularly when they're flat or small (under 5 millimeters), one expert in the United States said.

Their study of almost 16,000 patients who underwent colonoscopy found that the long-term risk for colon cancer was 2.5 times greater for those with advanced polyps, compared to people without such growths.

Heather Blackburn-Beel was 38 years old when she died from colon cancer, an example of a troubling rise of the cancer's incidence in young adults.

Flexible sigmoidoscopy looks at about a third of the colon, as compared to the whole colon as is seen in colonoscopy. But unlike colonoscopy, sigmoidoscopy does not typically require sedation.

In the new study, researchers tracked data on more than 32,000 women in the United Kingdom who were followed for an average of 17 years.

The study looked at roughly 25,000 patients in the Veterans Affairs (VA) health system, where colonoscopy is widely used. The VA views it as the main screening test for patients aged 50 and older who have average odds for developing colon or rectal cancer.

Polyps are not cancerous, but some can eventually turn into cancer if they're not removed.

Though the appendicitis risk is small, it's at least four times higher the week after a colonoscopy than in the 51 weeks that follow, the study found. And by some measures, the increase is 12 times higher.

These foods all increase inflammation in your body, and the inflammation they cause is associated with a higher chance of developing colon cancer, according to pooled data from two major health studies.

The test detects so-called "circulating tumor cells" (CTCs). Researchers tested it on 620 people in Taiwan who were scheduled for a routine colonoscopy at a local hospital.

Among people treated for non-metastatic colon cancer, every 5 grams of fiber added to their diet reduced their odds of dying by nearly 25 percent, said lead researcher Dr. Andrew Chan. He is an associate professor in the department of medicine at Harvard Medical School.

Currently, people at average risk of colon cancer are told to start screening for the disease at age 50. But a new study raises the question of whether earlier screening could be better.
