Fat in the diet

Inconclusive: The evidence is too limited to determine the likelihood of an association with increased or decreased risk of endometrial cancer.

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.

A high-fat diet has been shown to increase levels of the female hormone oestrogen and other hormones that are known to increase the risk of endometrial cancer. This has led researchers to look at whether a high-fat diet affects the risk of endometrial cancer.

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