Overweight and obesity have reached pandemic levels on a worldwide basis and are associated with increased risk and worse prognosis for many but not all malignancies. Pathophysiologic processes that affect this association are reviewed, with a focus on the relation of type 2 diabetes mellitus with cancer, lessons learned from the use of murine models to study the association, the impact of obesity on pancreatic cancer, the effect of dietary fats and cholesterol as cancer promoters, and the mechanisms by which the intestinal microbiome affects obesity and cancer.
