There is no conclusive evidence that eating foods containing high levels of fat* or cholesterol is associated with increased risk of endometrial cancer. Results from studies are not consistent, and these studies are of poor quality.

*Studies have looked at diets containing high levels of total fat, animal fat, cholesterol and saturated fats.
