Using data from meta-analyses or pooled analyses, the researchers concluded the following: For cancers of the colon, stomach, liver, gallbladder, pancreas and kidney; they found increased relative risks of 1.2 to 1.5 for those overweight (BMI 25-29.9) and 1.5 to 1.8 for those with obesity (BMI over 30).
For those with extreme obesity (BMI of 40 or more), the relative risk for esophageal adenoarcinoma was 4.8. The evidence for the various types of cancers was not always strong, but there were some for which the working group found sufficient evidence….
The authors commented, “On the basis of the available data, we concluded that the absence of excess body fatness lowers the risk of most cancers.”
Although many of these increases in relative risk are small, the fact that…over 600 million adults are obese worldwide means that even a small increase in risk could have a substantial impact on cancer rate.
