Colorectal Cancer Increases with Weight

Posted on February 26 2014

In a recent study funded by the U.S. Cancer Institute, a correlation was found between increased weight and the incidence of colon polyps. This information can help to identify risks and prevention techniques to help lower the incidence of colorectal cancer.


Research performed at the MichiganStateUniversity documented the weight, BMI, waist measurements, and leptin levels for all participants between the ages of 48-65. What the study found was that the incidence of colon polyps was lowest for lean men, but increased for overweight and obese men.


The study results were as follows:

- 30% of overweight or obese men had at least one colon polyp - Obese men were 8 times more likely than lean men to have one colon polyp - Obese men were 6.5 times more likely to have 3 colon polyps than lean men


Thus far researchers have declined to conclusively state a cause and effect relationship; however, there certainly does appear to be a correlation. Interestingly, it was also found that there was an incremental increase in colon polyps between lean to overweight men, and overweight to obese men.


Colon cancer has been noted as a significant cause of cancer related deaths in the United States. Studies such as these can help identify risk factors for the development of potentially harmful colon polyps. Screening for colon cancer is recommended for individuals over the age of 50 and can be performed by a physician, or even using an at-home test kit.
