It’s common knowledge that as a country, we’ve been getting fatter for decades. In some states the prevalence of obesity is over 35 percent, as it is in adults over all, as shown in the graphic below.

Probably it’s less widely known that there are at least 13 different types of cancer that are associated with overweight (BMI = 25-29.9) and obesity (BMI = or > 30), according to Dr. C. Brooke Steele of the CDC, and colleagues. These include: adenocarcinoma of the esophagus; cancers of the breast [in postmenopausal women], colon and rectum, endometrium, gallbladder, gastric cardia, kidney, liver, ovary, pancreas, and thyroid; meningioma; and multiple myeloma.

These investigators used data from the US Cancer Statistics database for 2014 to determine new cases of such cancers, as well as assessing trends between 2005 and 2014. They reported that approximately 40 percent of cancers diagnosed in 2014 were among those associated with overweight and obesity and affected about 631,000 persons.

These data indicate that during the period when many of the risks of overweight and obesity became widely known, both the occurrence of excess body fat as well as associated kinds of cancers were increasing. Clearly, more must be done to target populations at the greatest risk of overweight and obesity; if there is truly a causal link between overweight, obesity and these cancers, then reducing the prevalence of excess avoirdupois could also reduce the incidence of such cancers.
