Obesity shortens colon cancer survival

11th April 2014

The study included more than 6,700 colon cancer patients. They all calculated their body mass index (BMI) based on self-reports, two years before diagnosis. The patients were followed for an average of five years.


BMI is a measurement of body fat based on weight and height. A BMI of 30 or more is considered obese.

A higher BMI before diagnosis was associated with increased risk of death from colon cancer and all other causes. The association does not prove a cause-and-effect relationship.

It was found that, for every 5-point increase in BMI, there was a seven percent higher risk of death from colon cancer and ten-percent higher risk of death from all causes.

The study was scheduled for presentation at the annual meeting of the American Association for Cancer Research in San Diego.
