[Recommendation] Watch the meat [Why] 
Some studies have shown that eating meat is linked to increased breast cancer risk, although the association may depend on whether the meat is well-done, which introduces more carcinogens. Most,118 , 119 but not all,120 studies show that consumption of meat is associated with an increased risk of breast cancer. This association probably depends in part on how well the meat is cooked. Well-done meat contains more carcinogenic material than does lightly cooked meat.121 Evidence from preliminary studies shows that women who eat well-done meat have a high risk of breast cancer.122 Genetic factors may determine which women increase their risk of breast cancer by eating well-done meat.123
