By Genevra Pittman NEW YORK (Reuters Health) – Women who eat a lot of fat, particularly saturated fat, may be at higher risk of certain types of breast cancer, new research suggests. Past studies have come to differing conclusions on a possible association between dietary fat and breast cancer. Still, it cannot prove that a high-fat diet is the reason any of the women got cancer. “In our study we confirm that saturated fat intake was positively associated with breast cancer risk,” lead author Sabina Sieri, from the Fondazione IRCCS National Cancer Institute in Milan, Italy, told Reuters Health in an email.
