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 drinking alcohol is associated with risk of endometrial cancer.

Results from studies of alcohol intake and risk of endometrial cancer are not consistent. Most studies have found no association between drinking alcohol and endometrial cancer risk.

A few studies have reported either an increased risk or a decreased risk of endometrial cancer in women who drink alcohol. Where a lower risk was seen, this was in women who drank small amounts of alcohol. However, it is not clear whether the lower risk was due to alcohol or other factors.

It is possible that drinking alcohol affects different hormonal pathways which can increase and decrease the growth of endometrial cells and therefore risk of endometrial cancer.

It is important to note that drinking alcohol is associated with an increased risk of several other cancers, including cancers of the mouth and throat, digestive system (oesophagus, colon and rectum), liver, and breast.
