3 cups of coffee a day to reduce breast cancer concerns

Compared to people who do not drink coffee, the risk of developing breast cancer in people who drink this bitter sweet substance often can be reduced by two-thirds. However, this is only true for some people with special gene mutations.

The anti-breast cancer effect of coffee comes from the abundance of phytoestrogen (a group of natural protective substances), said Dr. Steven A. Narod, University of Toronto (Canada). Narod and colleagues investigated the relationship between coffee and the risk of breast cancer in about 1,700 people at high risk for carrying mutations of BRCA1 and BRCA2 genes. These people come from 40 medical centers in 4 countries.

The results showed that, compared with the non-drinkers, the risk of developing breast cancer among coffee drinkers decreased by 10%, 25% and 69% in groups drinking the same 1-3 cups, 4-5 or 6 cups of coffee. coffee every day or more. The reason is that "coffee phytoestrogens have a structure similar to endogenous estrogen, but are able to neutralize estrogen receptors," Narod explained.

When assessing the effect of coffee on mutant subgroups, the team found that this charming sweet drink effectively protects the BRCA1 mutant group, but does not favor the BRCA2 group.
