4 cups of coffee a day may cut cancer risk
Drinking four or more cups of coffee a day may reduce risk of developing endometrial cancer by almost 25 per cent, a new study has suggested.
Originating in the lining of the uterus, endometrial cancer is one of the most widespread invasive gynaecological cancers.
High levels of oestrogen and insulin are associated with an increased risk of the disease but researchers involved in the Nurses` Health Study from the Department of Nutrition at the Harvard School of Public Health have discovered that high-coffee-consuming women have lower levels of these hormones, compared with those who drink little or no coffee, Stuff.co.nz reported.
`This is an observational study – coffee intake is self-selected, not randomised – so our study cannot prove causal relationship between coffee and endometrial cancer risk, but we found an inverse association between coffee and endometrial cancer risk,` said study author Youjin Je, doctoral student at the Harvard School of Public Health.
`Four or more cups of coffee may contribute to lower risk of endometrial cancer by lowering levels of oestrogen and insulin which are related to endometrial carcinogenesis due to increased cell proliferation and reduced cell death,` Je noted.
