Breast Cancer Risk Reduced by Consuming Caffeinated
Caffeinated Coffee may reduce the risk of breast cancer in women,
according to a new Canadian study. The researchers examined women with
a particular type of cancer associated with a specific gene mutation.
The research is especially important for women with a family history of

with the BRCA1 and BRCA2 gene mutations the researchers found that women
that drank more coffee had less of a risk of developing breast cancer.
According to the CTV Canadian website, Professor Steven A. Narod at the
University of Toronto said “"Those women who drank six or more cups of
coffee a day on average had about a 75 per cent reduction in the risk of
breast cancer." The women who drank 4 to 5 cups of coffee per day were
able to reduce their risk 25% according to Reuters. Reuters also claims
the risk reduction for 6 or more cups per day was 69%.
Even three cups of coffee a day lowered the risk 10 percent. The
patients with the BRCA1 gene mutation benefited from coffee consumption
while the patients with BRCA2 gene mutation had negligible benefits.
This is according to the research published in the January edition of
the International Journal of Cancer.
The published study said "These results suggest that among women with
BRCA gene mutation, coffee consumption is unlikely to be harmful and
that high levels of consumption may in fact be related to reduced breast
The study included 1,690 women participants from four countries. The
women were questioned about their lifetime coffee consumption through
questionnaires. They found that decaffeinated coffee consumption had no
effect on breast cancer rates. The reduced cancer risk may be due to
phtoestrogens found in the coffee.
Narod also said "If we can understand how it is that coffee exactly went
about preventing breast cancer that may give us a clue to other
preventative treatments we can do without the side effects of drinking
that much coffee."
"The mechanism by which phytoestrogens may beneficially influence the
risk of breast cancer has predominantly been attributed to their
structural similarity to endogenous estrogens and their ability to bind
to estrogen receptors," Narod said as reported by Reuters.
