Women who eat a lot of meat, particularly red or processed meats, may be more likely to develop breast cancer, according to a large study of British women.
Researchers found that among 35,372 women, between the ages of 35 and 69 years old, who were followed for 8 years, those who ate the largest amount of meat were more likely than non-meat eaters to develop breast cancer before or after menopause.
The link was stronger among postmenopausal women, with red and processed meat seeming to particularly raise their risk of breast cancer. Women who ate the most red meat (2 or more ounces per day) were 56 percent more likely to develop breast cancer than the women who ate no red meat.
Meanwhile, those who ate the most processed meat (more than three quarters of an ounce per day) showed a 64-percent increase in their risk of the disease.
