Eating fruits and vegetables was not strongly associated with decreased colon cancer risk, according to a study published online in the September 25 Journal of the National Cancer Institute.
Several studies have examined the relationship between colon cancer and fruit and vegetable intake, but the results have been inconsistent. A team of researchers led by Anita Koushik, Ph.D., formerly of the Harvard School of Public Health in Boston, analyzed the association between fruit and vegetable intake and colon cancer risk by pooling the results of 14 studies that included 756,217 men and women who were followed for 6 to 20 years.
Their analysis showed that while fruit and vegetable intake was not strongly associated with overall colon cancer risk, there may be a lower risk of cancer of the distal colon—the left-hand side of the colon—among those who consumed the largest amounts of fruits and vegetables. However, the difference in the associations for cancers on the left and right sides was not statistically significant.
“Results for each fruit and vegetable group were generally consistent between men and women,” the authors write.

Increased glucose level is a strong risk factor for colorectal cancer
Diabetes is a very common illness that affects more than 20 million people in the U.S. and it is estimated an additional 54 million Americans have pre-diabetes, a condition that occurs when a person's blood glucose levels are higher than normal but not high enough for a diagnosis of type 2 diabetes. Therefore, it is important to determine whether glucose and insulin levels are associated with a higher risk of colon polyps, the precursor lesions to colon cancer.

Study confirms colonoscopy associated with reduced colorectal cancer incidence
Patients who undergo a complete negative colonoscopy have a reduced incidence of colorectal cancer, confirms a study published in Clinical Gastroenterology and Hepatology. However, in the proximal colon, the incidence reduction of colorectal cancer following complete negative colonoscopy differs in magnitude and timing.
