MedicalResearch.com: What are the main findings of the study?
Answer: In our study, postmenopausal women who reported higher consumption of sugar-sweetened beverages were more likely to develop estrogen-dependent type I endometrial cancer, the most common type of this cancer.
MedicalResearch.com: Were any of the findings unexpected?
Answer: Although we are the first to show this association, it is not surprising that women who drank more sugar-sweetened beverages had higher risk of type I endometrial cancer but not estrogen-independent type II endometrial cancer. Other studies have shown that the increasing consumption of sugar-sweetened beverages has paralleled the increase in obesity. Obese women are likely to have higher circulating levels of estrogens and insulin, which are known risk factors for type I endometrial cancer.
MedicalResearch.com: What should clinicians and patients take away from your report?
Answer: Although our study findings are interesting, we are the first to show the association between sugar-sweetened beverage consumption and the risk of endometrial cancer. Because ours is an observational study, it is not possible to establish a causal link between sugar-sweetened beverages and endometrial cancer. Therefore, our findings need to be replicated. Individuals should follow current dietary guidelines to avoid sugar-sweetened beverages. Too much added sugar from any source can elevate person’s overall calorie intake and may increase the risk of a number of health conditions such as obesity, diabetes, heart disease as well as cancer.
MedicalResearch.com: What recommendations do you have for future research as a result of this study?
Answer: Because this study is the first to show the association between high sugar-sweetened beverage consumption and endometrial cancer, such findings may be due to chance and need replication in other studies.
