Obesity linked to increased risk of esophageal cancer

Writing in the aptly named online journal Gut, Australian researchers have discovered a disproportionate incidence of increased esophageal cancers in overweight individuals.

According to the researchers, those with a "body mass index (BMI) of 40 or more, were six times as likely than those with a BMI of between 18.25 and 25."

Gastric reflux increased the incidence of this cancer 5X, and combined with obesity, the risk increased 15X.

Men 50 years old and younger were particularly vulnerable.
