Coffee and cancer of the prostate (Thursday 19 may) :
An American study by the Harvard School of Public Health (HSPH) demonstrates that men who eat a lot of coffee have less risk of developing cancer of the prostate.
"Few studies have specifically investigated the association of coffee consumption and the risk of fatal prostate cancer., the most critical form of the disease. Our study is the largest to date to consider whether coffee may reduce this risk"said Lorelei Mucci, the lead author of the study. Indeed, the study was conducted on 47 911 U.S. 1986 to 2008. Among these men, 5 035 prostate cancers have been reported, whose 642 mortals.
The study concluded that a man drinking six cafes or more per day, has decreased almost by 20% risk of contracting prostate cancer. This man has also decreased from 60% risk of developing a fatal cancer of the prostate. One to three cups of coffee per day would be sufficient to reduce this rate to 30%.
Caffeine in coffee is not at the origin of this observation because even with a decaffeinated coffee the same results were observed. As for breast cancer, researchers believe that antioxidant and anti-inflammatory beverage properties would be at the origin of these benefits.
It should be remembered that 40 000 cases of prostate cancer are discovered each year and that 10 000 of them are fatal. Furthermore, "25% of new cases of cancer found in men are prostate cancers." .
Coffee and breast cancer (Sunday 15 may) :
A recent study, published in Breast Cancer Research the 11 may, shows that a high consumption of coffee can reduce the risk of developing breast cancer.

The decrease in the risk of cancer of the breast in general, but this time without taking into account all these factors apart from age, with the same consumption of coffee was reduced by 20%.
These results are however conflicted with other studies published a few years ago. Scientists are not yet able to fully determine the reason for these beneficial effects. Indeed, There are in the Café more of 800 different compounds. Further studies should be made to clarify the situation.
