A study conducted by researchers from Loma Linda University in California indicated that the risk of developing breast cancer increases in women who drink two cups of milk per day by 80 percent, according to the British "Daily Mail" website.

The study included 53,000 women who were followed over the course of 8 years, and found that consumption of a small amount of milk also was associated with breast cancer injuries.

And linked to eating a third of a cup of milk, equivalent to a small cup of latte, increases the risk of maintenance by 30 percent, while eating a full glass of milk a day equivalent to "250" ml raise the risk of infection by 50 percent.

As for those who drink two to three cups a day, this percentage has increased to between 70 and 80 per cent, and this percentage increases with the increase in the amount to reach a high probability of its occurrence with the increase in the amount of milk to two cups per day.

Although the study is observational and cannot be proven, scientists believe that a hormone present in cow's milk may be the cause.
